RT::Config

DESCRIPTION

RT has dozens of configuration options to customize how RT behaves for different situations. The available options and valid values are described below.

Server Configuration Files

This file, etc/RT_Config.pm, defines the available configuration options and sets the defaults for RT. You should never edit this file directly. If you do, your changes will be lost when you upgrade and RT installs the newest version of this file on your system.

The correct place to set site-specific options is in etc/RT_SiteConfig.pm. If you have many customizations to manage, you can break your configuration into multiple files and put them in a directory etc/RT_SiteConfig.d/. More information about this option is available in the RT::Config documentation.

Web Configuration

RT also allows you to set configuration via the RT web interface at Admin > Tools > System Configuration. Any configuration options set there take precedence over values set in etc/RT_SiteConfig.pm. If you provide a custom setting in both places, RT will issue a warning in the log as a reminder to consider removing the setting from etc/RT_SiteConfig.pm to avoid confusion.

Some settings that are core to RT cannot be changed via the web interface. This prevents changes that could make your RT inoperable, leaving you unable to restore the system via the web UI.

System

Base configuration

$rtname

$rtname is the string that RT will look for in mail messages to figure out what ticket a new piece of mail belongs to.

Your domain name is recommended, so as not to pollute the namespace. Once you start using a given tag, you should probably never change it; otherwise, mail for existing tickets won't get put in the right place.

$Organization

You should set this to your organization's DNS domain. For example, fsck.com or asylum.arkham.ma.us. It is used by the linking interface to guarantee that ticket URIs are unique and easy to construct. Changing it after you have created tickets in the system will break all existing ticket links!

$CorrespondAddress, $CommentAddress

RT is designed such that any mail which already has a ticket-id associated with it will get to the right place automatically.

$CorrespondAddress and $CommentAddress are the default addresses that will be listed in From: and Reply-To: headers of correspondence and comment mail tracked by RT, unless overridden by a queue-specific address. They should be set to email addresses which have been configured as aliases for rt-mailgate.

$WebDomain

Domain name of the RT server, e.g. 'www.example.com'. It should not contain anything except the server name.

$WebPort

If we're running as a superuser, run on port 80. Otherwise, pick a high port for this user.

443 is default port for https protocol.

$WebPath

If you're putting the web UI somewhere other than at the root of your server, you should set $WebPath to the path you'll be serving RT at.

$WebPath requires a leading / but no trailing /, or it can be blank.

In most cases, you should leave $WebPath set to "" (an empty value).

$Timezone

$Timezone is the default timezone, used to convert times entered by users into GMT, as they are stored in the database, and back again; users can override this. It should be set to a timezone recognized by your server.

@Plugins

Once a plugin has been downloaded and installed, use Plugin() to add to the enabled @Plugins list:

    Plugin( "RT::Extension::JSGantt" );

RT will also accept the distribution name (i.e. RT-Extension-JSGantt) instead of the package name (RT::Extension::JSGantt).

@StaticRoots

Set @StaticRoots to serve extra paths with a static handler. The contents of each hashref should be the the same arguments as Plack::Middleware::Static takes. These paths will be checked before any plugin or core static paths.

Example:

    Set( @StaticRoots,
        {
            path => qr{^/static/},
            root => '/local/path/to/static/parent',
        },
    );

Database connection

$DatabaseType

Database driver being used; case matters. Valid types are "mysql", "Oracle", and "Pg". "SQLite" is also available for non-production use.

$DatabaseHost, $DatabaseRTHost

The domain name of your database server. If you're running MySQL and on localhost, leave it blank for enhanced performance.

DatabaseRTHost is the fully-qualified hostname of your RT server, for use in granting ACL rights on MySQL.

$DatabasePort

The port that your database server is running on. Ignored unless it's a positive integer. It's usually safe to leave this blank; RT will choose the correct default.

$DatabaseUser

The name of the user to connect to the database as.

$DatabasePassword

The password the $DatabaseUser should use to access the database.

$DatabaseName

The name of the RT database on your database server. For Oracle, the SID and database objects are created in $DatabaseUser's schema.

%DatabaseExtraDSN

Allows additional properties to be passed to the database connection step. Possible properties are specific to the database-type; see https://metacpan.org/pod/DBI#connect

For PostgreSQL, for instance, the following enables SSL (but does no certificate checking, providing data hiding but no MITM protection):

   # See https://metacpan.org/pod/DBD::Pg#connect
   # and http://www.postgresql.org/docs/8.4/static/libpq-ssl.html
   Set( %DatabaseExtraDSN, sslmode => 'require' );

For MySQL, the following acts similarly if the server has enabled SSL. Otherwise, it provides no protection; MySQL provides no way to force SSL connections:

   # See https://metacpan.org/pod/DBD::mysql#connect
   # and http://dev.mysql.com/doc/refman/5.1/en/ssl-options.html
   Set( %DatabaseExtraDSN, mysql_ssl => 1 );

$DatabaseAdmin

The name of the database administrator to connect to the database as during upgrades.

Logging

The default is to log anything except debugging information to syslog. Check the Log::Dispatch POD for information about how to get things by syslog, mail or anything else, get debugging info in the log, etc.

It might generally make sense to send error and higher by email to some administrator. If you do this, be careful that this email isn't sent to this RT instance. Mail loops will generate a critical log message.

$LogToSyslog, $LogToSTDERR

The minimum level error that will be logged to the specific device. From lowest to highest priority, the levels are:

    debug info notice warning error critical alert emergency

Many syslogds are configured to discard or file debug messages away, so if you're attempting to debug RT you may need to reconfigure your syslogd or use one of the other logging options.

Logging to your screen affects scripts run from the command line as well as the STDERR sent to your webserver (so these logs will usually show up in your web server's error logs).

$LogToFile, $LogDir, $LogToFileNamed

Logging to a standalone file is also possible. The file needs to both exist and be writable by all direct users of the RT API. This generally includes the web server and whoever rt-crontool runs as. Note that rt-mailgate and the RT CLI go through the webserver, so their users do not need to have write permissions to this file. If you expect to have multiple users of the direct API, Best Practical recommends using syslog instead of direct file logging.

You should set $LogToFile to one of the levels documented above.

$LogStackTraces

If set to a log level then logging will include stack traces for messages with level equal to or greater than specified.

NOTICE: Stack traces include parameters supplied to functions or methods. It is possible for stack trace logging to reveal sensitive information such as passwords or ticket content in your logs.

@LogToSyslogConf

Additional options to pass to Log::Dispatch::Syslog; the most interesting flags include facility, logopt, and possibly ident. See the Log::Dispatch::Syslog documentation for more information.

Incoming mail gateway

$EmailSubjectTagRegex

This regexp controls what subject tags RT recognizes as its own. If you're not dealing with historical $rtname values, or historical queue-specific subject tags, you'll likely never have to change this configuration.

Be very careful with it. Note that it overrides $rtname for subject token matching.

The setting below would make RT behave exactly as it does without the setting enabled.

$OwnerEmail

$OwnerEmail is the address of a human who manages RT. RT will send errors generated by the mail gateway to this address. Because RT sends errors to this address, it should not be an address that's managed by your RT instance, to avoid mail loops.

$LoopsToRTOwner

If $LoopsToRTOwner is defined, RT will send mail that it believes might be a loop to $OwnerEmail.

$StoreLoops

If $StoreLoops is defined, RT will record messages that it believes to be part of mail loops. As it does this, it will try to be careful not to send mail to the sender of these messages.

$MaxAttachmentSize

$MaxAttachmentSize sets the maximum size (in bytes) of attachments stored in the database. This setting is irrelevant unless one of $TruncateLongAttachments or $DropLongAttachments (below) are set, OR the database is stored in Oracle. On Oracle, attachments larger than this can be fully stored, but will be truncated to this length when read.

$TruncateLongAttachments

If this is set to a non-undef value, RT will truncate attachments longer than $MaxAttachmentSize.

$DropLongAttachments

If this is set to a non-undef value, RT will silently drop attachments longer than MaxAttachmentSize. $TruncateLongAttachments, above, takes priority over this.

$RTAddressRegexp

$RTAddressRegexp is used to make sure RT doesn't add itself as a ticket CC if $ParseNewMessageForTicketCcs, above, is enabled. It is important that you set this to a regular expression that matches all addresses used by your RT. This lets RT avoid sending mail to itself. It will also hide RT addresses from the list of "One-time Cc" and Bcc lists on ticket reply.

If you have a number of addresses configured in your RT database already, you can generate a naive first pass regexp by using:

    perl etc/upgrade/generate-rtaddressregexp

If left blank, RT will compare each address to your configured $CorrespondAddress and $CommentAddress before searching for a Queue configured with a matching "Reply Address" or "Comment Address" on the Queue Admin page.

$CanonicalizeEmailAddressMatch, $CanonicalizeEmailAddressReplace

RT provides functionality which allows the system to rewrite incoming email addresses, using "CanonicalizeEmailAddress" in RT::User. The default implementation replaces all occurrences of the regular expression in CanonicalizeEmailAddressMatch with CanonicalizeEmailAddressReplace, via s/$Match/$Replace/gi. The most common use of this is to replace @something.example.com with @example.com. If more complex noramlization is required, "CanonicalizeEmailAddress" in RT::User can be overridden to provide it.

$ValidateUserEmailAddresses

By default $ValidateUserEmailAddresses is 1, and RT will refuse to create users with an invalid email address (as specified in RFC 2822) or with an email address made of multiple email addresses.

Set this to 0 to skip any email address validation. Doing so may open up vulnerabilities.

@MailPlugins

@MailPlugins is a list of authentication plugins for RT::Interface::Email to use; see rt-mailgate

$ExtractSubjectTagMatch, $ExtractSubjectTagNoMatch

The default "extract remote tracking tags" scrip settings; these detect when your RT is talking to another RT, and adjust the subject accordingly.

$CheckMoreMSMailHeaders

Some email clients create a plain text version of HTML-formatted email to help other clients that read only plain text. Unfortunately, the plain text parts sometimes end up with doubled newlines and these can then end up in RT. This is most often seen in MS Outlook.

Enable this option to have RT check for additional mail headers and attempt to identify email from MS Outlook. When detected, RT will then clean up double newlines. Note that it may clean up intentional double newlines as well.

$TreatAttachedEmailAsFiles

Email coming into RT can sometimes have another email attached, when an email is forwarded as an attachment, for example. By default, RT recognizes that the attached content is an email and does some processing, including some parsing the headers of the attached email. You can see this in suggested email addresses on the People page and One-time Cc on reply.

If you want RT to treat attached email files as regular file attachments, set this option to true (1). With this option enabled, attached email will show up in the "Attachments" section like other types of file attachments and content like headers will not be processed.

Outgoing mail

$MailCommand

$MailCommand defines which method RT will use to try to send mail. We know that 'sendmailpipe' works fairly well. If 'sendmailpipe' doesn't work well for you, try 'sendmail'. 'qmail' is also a supported value.

For testing purposes, or to simply disable sending mail out into the world, you can set $MailCommand to 'mbox' which logs all mail, in mbox format, to files in /opt/rt5/var/ based in the process start time. The 'testfile' option is similar, but the files that it creates (under /tmp) are temporary, and removed upon process completion; the format is also not mbox-compatable.

$SetOutgoingMailFrom

$SetOutgoingMailFrom tells RT to set the sender envelope to the Correspond mail address of the ticket's queue.

Warning: If you use this setting, bounced mails will appear to be incoming mail to the system, thus creating new tickets.

If the value contains an @, it is assumed to be an email address and used as a global envelope sender. Expected usage in this case is to simply set the same envelope sender on all mail from RT, without defining $OverrideOutgoingMailFrom. If you do define $OverrideOutgoingMailFrom, anything specified there overrides the global value (including Default).

This option only works if $MailCommand is set to 'sendmailpipe'.

$OverrideOutgoingMailFrom

$OverrideOutgoingMailFrom is used for overwriting the Correspond address of the queue as it is handed to sendmail -f. This helps force the From_ header away from www-data or other email addresses that show up in the "Sent by" line in Outlook.

The option is a hash reference of queue id/name to email address. If there is no ticket involved, then the value of the Default key will be used.

This option only works if $SetOutgoingMailFrom is enabled and $MailCommand is set to 'sendmailpipe'.

$DefaultMailPrecedence

$DefaultMailPrecedence is used to control the default Precedence level of outgoing mail where none is specified. By default it is bulk, but if you only send mail to your staff, you may wish to change it.

Note that you can set the precedence of individual templates by including an explicit Precedence header.

If you set this value to undef then we do not set a default Precedence header to outgoing mail. However, if there already is a Precedence header, it will be preserved.

$OverrideMailPrecedence

$OverrideMailPrecedence is used for overwriting the $DefaultMailPrecedence value for a queue.

The option is a hash reference of queue id/name to precedence. If you set the precedence to undef, a Precedence header will not be added to the mail.

This option only works if $DefaultMailPrecedence is enabled.

$DefaultErrorMailPrecedence

$DefaultErrorMailPrecedence is used to control the default Precedence level of outgoing mail that indicates some kind of error condition. By default it is bulk, but if you only send mail to your staff, you may wish to change it.

If you set this value to undef then we do not add a Precedence header to error mail.

$UseOriginatorHeader

$UseOriginatorHeader is used to control the insertion of an RT-Originator Header in every outgoing mail, containing the mail address of the transaction creator.

$UseFriendlyFromLine

By default, RT sets the outgoing mail's "From:" header to "SenderName via RT". Setting $UseFriendlyFromLine to 0 disables it.

$FriendlyFromLineFormat

sprintf() format of the friendly 'From:' header; its arguments are SenderName and SenderEmailAddress.

$UseFriendlyToLine

RT can optionally set a "Friendly" 'To:' header when sending messages to Ccs or AdminCcs (rather than having a blank 'To:' header.

This feature DOES NOT WORK WITH SENDMAIL[tm] BRAND SENDMAIL. If you are using sendmail, rather than postfix, qmail, exim or some other MTA, you _must_ disable this option.

$FriendlyToLineFormat

sprintf() format of the friendly 'To:' header; its arguments are WatcherType and TicketId.

$NotifyActor

By default, RT doesn't notify the person who performs an update, as they already know what they've done. If you'd like to change this behavior, Set $NotifyActor to 1

$RecordOutgoingEmail

By default, RT records each message it sends out to its own internal database. To change this behavior, set $RecordOutgoingEmail to 0

If this is disabled, users' digest mail delivery preferences (i.e. EmailFrequency) will also be ignored.

$VERPPrefix, $VERPDomain

Setting these options enables VERP support http://cr.yp.to/proto/verp.txt.

Uncomment the following two directives to generate envelope senders of the form ${VERPPrefix}${originaladdress}@${VERPDomain} (i.e. rt-jesse=fsck.com@rt.example.com ).

This currently only works with sendmail and sendmailpipe.

$ForwardFromUser

By default, RT forwards a message using queue's address and adds RT's tag into subject of the outgoing message, so recipients' replies go into RT as correspondents.

To change this behavior, set $ForwardFromUser to 1 and RT will use the address of the current user and remove RT's subject tag.

$HTMLFormatter

RT's default pure-perl formatter may fail to successfully convert even on some relatively simple HTML; this will result in blank text/plain parts, which is particuarly unfortunate if HTML templates are not in use.

If the optional dependency HTML::FormatExternal is installed, RT will use external programs to render HTML to plain text. The default is to try, in order, w3m, elinks, html2text, links, lynx, and then fall back to the core pure-perl formatter if none are installed.

Set $HTMLFormatter to one of the above programs (or the full path to such) to use a different program than the above would choose by default. Setting this requires that HTML::FormatExternal be installed.

If the chosen formatter is not in the webserver's $PATH, you may set this option the full path to one of the aforementioned executables.

Email dashboards

$DashboardAddress

The email address from which RT will send dashboards. If none is set, then $OwnerEmail will be used.

$DashboardSubject

Lets you set the subject of dashboards. Arguments are the frequency (Daily, Weekly, Monthly) of the dashboard and the dashboard's name.

@EmailDashboardRemove

A list of regular expressions that will be used to remove content from mailed dashboards.

@EmailDashboardLanguageOrder

A list that specifies which language to use for dashboard subscription email. There are several special keys:

* _subscription: the language chosen on the dashboard subscription page * _recipient: the recipient's language, as chosen on their "About Me" page * _subscriber: the subscriber's language, as chosen on their "About Me" page

The first key that produces a value is used for the email. Be aware that users may not actually have a language set on their "About Me" page, since RT falls back to the language their web browser specifies (and of course in a scheduled email dashboard, there is no web browser).

You may also include a specific language as a fallback when there is no language specified otherwise. Using a specific language never fails to produce a value, so subsequent values in the list will never be considered.

By default, RT examines the subscription, then the recipient, then subscriber, then finally falls back to English.

Sendmail configuration

These options only take effect if $MailCommand is 'sendmail' or 'sendmailpipe'

$SendmailArguments

$SendmailArguments defines what flags to pass to $SendmailPath These options are good for most sendmail wrappers and work-a-likes.

These arguments are good for sendmail brand sendmail 8 and newer: Set($SendmailArguments,"-oi -ODeliveryMode=b -OErrorMode=m");

$SendmailBounceArguments

$SendmailBounceArguments defines what flags to pass to $Sendmail assuming RT needs to send an error (i.e. bounce).

$SendmailPath

If you selected 'sendmailpipe' above, you MUST specify the path to your sendmail binary in $SendmailPath.

Other mailers

@MailParams: @MailParams defines a list of options passed to $MailCommand if it is not 'sendmailpipe' or 'sendmail';

Application logic

$ParseNewMessageForTicketCcs

If $ParseNewMessageForTicketCcs is set to 1, RT will attempt to divine Ticket 'Cc' watchers from the To and Cc lines of incoming messages that create new tickets. This option does not apply to replies or comments on existing tickets. Be forewarned that if you have any addresses which forward mail to RT automatically and you enable this option without modifying $RTAddressRegexp below, you will get yourself into a heap of trouble.

See also the RT::Action::AutoAddWatchers extension which adds watchers from ticket replies on existing tickets.

$UseTransactionBatch

Set $UseTransactionBatch to 1 to execute transactions in batches, such that a resolve and comment (for example) would happen simultaneously, instead of as two transactions, unaware of each others' existence.

$StrictLinkACL

When this feature is enabled a user needs ModifyTicket rights on both tickets to link them together; otherwise, ModifyTicket rights on either of them is sufficient.

$RedistributeAutoGeneratedMessages

Should RT redistribute correspondence that it identifies as machine generated? A 1 will do so; setting this to 0 will cause no such messages to be redistributed. You can also use 'privileged' (the default), which will redistribute only to privileged users. This helps to protect against malformed bounces and loops caused by auto-created requestors with bogus addresses.

$ApprovalRejectionNotes

Should rejection notes from approvals be sent to the requestors?

$ForceApprovalsView

Should approval tickets only be viewed and modified through the standard approval interface? With this setting enabled (by default), any attempt to use the normal ticket display and modify page for approval tickets will be redirected.

For example, with this option set to 1 and an approval ticket #123:

    /Ticket/Display.html?id=123

is redirected to

    /Approval/Display.html?id=123

With this option set to 0, the redirect won't happen.

Extra security

This is a list of extra security measures to enable that help keep your RT safe. If you don't know what these mean, you should almost certainly leave the defaults alone.

$DisallowExecuteCode

If set to 1, the ExecuteCode right will be removed from all users, including the superuser. This is intended for when RT is installed into a shared environment where even the superuser should not be allowed to run arbitrary Perl code on the server via scrips.

$Framebusting

If set to 0, framekiller javascript will be disabled and the X-Frame-Options: DENY header will be suppressed from all responses. This disables RT's clickjacking protection.

$RestrictReferrer

If set to 0, the HTTP Referer (sic) header will not be checked to ensure that requests come from RT's own domain. As RT allows for GET requests to alter state, disabling this opens RT up to cross-site request forgery (CSRF) attacks.

$RestrictLoginReferrer

If set to 0, RT will allow the user to log in from any link or request, merely by passing in user and pass parameters; setting it to 1 forces all logins to come from the login box, so the user is aware that they are being logged in. The default is off, for backwards compatability.

@ReferrerWhitelist

This is a list of hostname:port combinations that RT will treat as being part of RT's domain. This is particularly useful if you access RT as multiple hostnames or have an external auth system that needs to redirect back to RT once authentication is complete.

 Set(@ReferrerWhitelist, qw(www.example.com:443  www3.example.com:80));

If the "RT has detected a possible cross-site request forgery" error is triggered by a host:port sent by your browser that you believe should be valid, you can copy the host:port from the error message into this list.

Simple wildcards, similar to SSL certificates, are allowed. For example:

    *.example.com:80    # matches foo.example.com
                        # but not example.com
                        #      or foo.bar.example.com

    www*.example.com:80 # matches www3.example.com
                        #     and www-test.example.com
                        #     and www.example.com

%ReferrerComponents

%ReferrerComponents is the hash to customize referrer checking behavior when $RestrictReferrer is enabled, where you can whitelist or blacklist the components along with their query args. e.g.

    Set( %ReferrerComponents,
        ( '/Foo.html' => 1, '/Bar.html' => 0, '/Baz.html' => [ 'id', 'results' ] )
    );

With this, '/Foo.html' will be whitelisted, and '/Bar.html' will be blacklisted. '/Baz.html' with id/results query arguments will be whitelisted but blacklisted if there are other query arguments.

$StrictContentTypes

If set to 0, the X-Content-Type-Options: nosniff header will be omitted on attachments. Because RT does not filter HTML content in unknown content types, disabling this opens RT up to cross-site scripting (XSS) attacks by allowing the execution of arbitrary Javascript when the browser detects HTML-looking data in an attachment with an unknown content type.

$BcryptCost

This sets the default cost parameter used for the bcrypt key derivation function. Valid values range from 4 to 31, inclusive, with higher numbers denoting greater effort.

Internationalization

@LexiconLanguages

An array that contains languages supported by RT's internationalization interface. Defaults to all *.po lexicons; setting it to qw(en ja) will make RT bilingual instead of multilingual, but will save some memory.

@EmailInputEncodings

An array that contains default encodings used to guess which charset an attachment uses, if it does not specify one explicitly. All options must be recognized by Encode::Guess.

The first element may also be *, which attempts encoding detection using Encode::Detect::Detector. This uses Mozilla's character detection library to examine the bytes, and use frequency metrics to rank the options. This detection may fail (and fall back to other options in the @EmailInputEncodings list) if no decoding has high enough confidence metrics. As of Encode::Detect::Detector version 1.01, it knows the following encodings:

    big5-eten
    cp1250
    cp1251
    cp1253
    cp1255
    cp855
    cp866
    euc-jp
    euc-kr
    euc-tw
    gb18030
    iso-8859-2
    iso-8859-5
    iso-8859-7
    iso-8859-11
    koi8-r
    MacCyrillic
    shiftjis
    utf-8

$EmailOutputEncoding

The charset for localized email. Must be recognized by Encode.

Date and time handling

$DateTimeFormat

You can choose date and time format. See the "Output formatters" section in perldoc lib/RT/Date.pm for more options. This option can be overridden by users in their preferences.

Some examples:

Set($DateTimeFormat, "LocalizedDateTime"); Set($DateTimeFormat, { Format = "ISO", Seconds => 0 });> Set($DateTimeFormat, "RFC2822"); Set($DateTimeFormat, { Format = "RFC2822", Seconds => 0, DayOfWeek => 0 });>

$DateDayBeforeMonth

Set this to 1 if your local date convention looks like "dd/mm/yy" instead of "mm/dd/yy". Used only for parsing, not for displaying dates.

$AmbiguousDayInPast, $AmbiguousDayInFuture

Should an unspecified day or year in a date refer to a future or a past value? For example, should a date of "Tuesday" default to mean the date for next Tuesday or last Tuesday? Should the date "March 1" default to the date for next March or last March?

Set $AmbiguousDayInPast for the last date, or $AmbiguousDayInFuture for the next date; the default is usually correct. If both are set, $AmbiguousDayInPast takes precedence.

$DefaultTimeUnitsToHours

Use this to set the default units for time entry to hours instead of minutes. Note that this only effects entry, not display.

$TimeInICal

By default, events in the iCal feed on the ticket search page contain only dates, making them all day calendar events. Set $TimeInICal if you have start or due dates on tickets that have significant time values and you want those times to be included in the events in the iCal feed.

This option can also be set as an individual user preference.

$PreferDateTimeFormatNatural

By default, RT parses an unknown date first with Time::ParseDate, and if this fails with DateTime::Format::Natural. $PreferDateTimeFormatNatural changes this behavior to first parse with DateTime::Format::Natural, and if this fails with Time::ParseDate. This gives you the possibility to use the more advanced features of DateTime::Format::Natural. For example with Time::ParseDate it isn't possible to get the 'first day of the last month', where DateTime::Format::Natural supports this with 'last month'.

Be aware that Time::ParseDate and DateTime::Format::Natural have different definitions for the relative date and time syntax. Time::ParseDate returns for 'last month' this DayOfMonth from the last month. DateTime::Format::Natural returns for 'last month' the first day of the last month. So changing this config option maybe changes the results of your saved searches.

Authorization and user configuration

$WebRemoteUserAuth

If $WebRemoteUserAuth is defined, RT will defer to the environment's REMOTE_USER variable, which should be set by the webserver's authentication layer.

$WebRemoteUserContinuous

If $WebRemoteUserContinuous is defined, RT will check for the REMOTE_USER on each access. If you would prefer this to only happen once (at initial login) set this to 0. The default setting will help ensure that if your webserver's authentication layer deauthenticates a user, RT notices as soon as possible.

$WebFallbackToRTLogin

If $WebFallbackToRTLogin is defined, the user is allowed a chance of fallback to the login screen, even if REMOTE_USER failed.

$LogoutURL

By default, $LogoutURL is set to RT's logout page. When an external service is used to log into RT, $LogoutURL can be set to the identity provider's logout URL. Include the full path to the logout endpoint, for example: 'https://www.example.com/logout'.

$WebRemoteUserGecos

$WebRemoteUserGecos means to match 'gecos' field as the user identity; useful with mod_auth_external.

$WebRemoteUserAutocreate

$WebRemoteUserAutocreate will create users under the same name as REMOTE_USER upon login, if they are missing from the Users table.

$UserAutocreateDefaultsOnLogin

If $WebRemoteUserAutocreate is set to 1, $UserAutocreateDefaultsOnLogin will be passed to "Create" in RT::User when the user is created. Use it to set default settings for the new user account, such as creating users as unprivileged with:

    Set($UserAutocreateDefaultsOnLogin, { Privileged => 0 });

or privileged:

    Set($UserAutocreateDefaultsOnLogin, { Privileged => 1 });

The settings must be in a hashref as shown.

This option is also used if you have External Auth configured. See "External Authentication and Authorization" for details.

$WebSessionClass

$WebSessionClass is the class you wish to use for storing sessions. On MySQL, Pg, and Oracle it defaults to using your database, in other cases sessions are stored in files using Apache::Session::File. Other installed Apache::Session::* modules can be used to store sessions.

    Set($WebSessionClass, "Apache::Session::File");

%WebSessionProperties

%WebSessionProperties is the hash to configure class "$WebSessionClass" in case custom class is used. By default it's empty and values are picked depending on the class. Make sure that it's empty if you're using DB as session backend.

$AutoLogoff

By default, RT's user sessions persist until a user closes his or her browser. With the $AutoLogoff option you can setup session lifetime in minutes. A user will be logged out if he or she doesn't send any requests to RT for the defined time.

$LogoutRefresh

The number of seconds to wait after logout before sending the user to the login page. By default, 1 second, though you may want to increase this if you display additional information on the logout page.

$WebSecureCookies

By default, RT's session cookie isn't marked as "secure". Some web browsers will treat secure cookies more carefully than non-secure ones, being careful not to write them to disk, only sending them over an SSL secured connection, and so on. To enable this behavior, set $WebSecureCookies to 1. NOTE: You probably don't want to turn this on unless users are only connecting via SSL encrypted HTTPS connections.

$WebHttpOnlyCookies

Default RT's session cookie to not being directly accessible to javascript. The content is still sent during regular and AJAX requests, and other cookies are unaffected, but the session-id is less programmatically accessible to javascript. Turning this off should only be necessary in situations with odd client-side authentication requirements.

$MinimumPasswordLength

$MinimumPasswordLength defines the minimum length for user passwords. Setting it to 0 disables this check.

External Authentication and Authorization

RT has a built-in module for integrating with a directory service like LDAP or Active Directory for authentication (login) and authorization (enabling/disabling users and setting user attributes). The core configuration settings for the service are listed here. Additional details are available in the RT::Authen::ExternalAuth module documentation.

See also "$UserAutocreateDefaultsOnLogin" for configuring defaults for autocreated users.

$ExternalSettings: This option, along with the following options, activate and configure authentication via a resource external to RT. All of the configuration for your external authentication service, like LDAP or Active Directory, are defined in a data structure in this option. You can find full details on the configuration options in the RT::Authen::ExternalAuth documentation.
$ExternalAuthPriority: Sets the priority of authentication resources if you have multiple configured. RT will attempt authorization with each resource, in order, until one succeeds or no more remain. See RT::Authen::ExternalAuth for details.
$ExternalInfoPriority: Sets the order of resources for querying user information if you have multiple configured. RT will query each resource, in order, until one succeeds or no more remain. See RT::Authen::ExternalAuth for details.
$UserAutocreateDefaultsOnLogin: A hashref of options to set for users who are autocreated on login via ExternalAuth. For example, you can automatically make "Privileged" users who were authenticated and created from LDAP or Active Directory. See RT::Authen::ExternalAuth for details.
$AutoCreateNonExternalUsers: Users should still be autocreated by RT as internal users if they fail to exist in an external service; this is so requestors who are not in LDAP can still be created when they email in. See RT::Authen::ExternalAuth for details.
$DisablePasswordForAuthToken: If you have a mix of RT and federated authentication, RT can't directly verify a user's password against the federated IdP. You can explicitly disable the password prompt when creating a token by setting this option to true (1).

Initialdata Formats

RT supports pluggable data format parsers for initialdata files.

If you add format handlers, note that you can remove the perl entry if you don't want it available. Removing the default perl entry may cause problems installing plugins and RT updates. If so, re-enable it temporarily.

$InitialdataFormatHandlers

Set the $InitialdataFormatHandlers to an arrayref containing a list of format handler modules. The 'perl' entry is the system default, and handles perl-style intialdata files.

The JSON format handler is also available in RT, but it is not loaded by default. Add it to your configuration as shown below to enable it.

    Set( $InitialdataFormatHandlers,
         [
            'perl',
            'RT::Initialdata::JSON',
            'RT::Extension::Initialdata::Foo',
            ...
         ]
       );

Development options

$DevelMode

RT comes with a "Development mode" setting. This setting, as a convenience for developers, turns on several of development options that you most likely don't want in production:

Disables CSS and JS minification and concatenation. Both CSS and JS will be instead be served as a number of individual smaller files, unchanged from how they are stored on disk.
Uses Module::Refresh to reload changed Perl modules on each request.
Turns off Mason's static_source directive; this causes Mason to reload template files which have been modified on disk.
Turns on Mason's HTML error_format; this renders compilation errors to the browser, along with a full stack trace. It is possible for stack traces to reveal sensitive information such as passwords or ticket content.
Turns off caching of callbacks; this enables additional callbacks to be added while the server is running.

$RecordBaseClass

What abstract base class should RT use for its records. You should probably never change this.

Valid values are DBIx::SearchBuilder::Record or DBIx::SearchBuilder::Record::Cachable

@MasonParameters

@MasonParameters is the list of parameters for the constructor of HTML::Mason's Apache or CGI Handler. This is normally only useful for debugging, e.g. profiling individual components with:

    use MasonX::Profiler; # available on CPAN
    Set(@MasonParameters, (preamble => 'my $p = MasonX::Profiler->new($m, $r);'));

$StatementLog

RT has rudimentary SQL statement logging support; simply set $StatementLog to be the level that you wish SQL statements to be logged at.

Enabling this option will also expose the SQL Queries page in the Admin -> Tools menu for SuperUsers.

SQL bind parameters

RT enables SQL bind parameters for all searches by default, which improves performance especially for Oracle. If you need to disable this for some reason, add this to config:

    $ENV{SB_PREFER_BIND} = 0;

Web interface

Base configuration

$WebDefaultStylesheet

This determines the default stylesheet the RT web interface will use. RT ships with several themes by default:

  elevator-light  The default light theme for RT 5
  elevator-dark   The dark theme for RT 5

This value actually specifies a directory in share/static/css/ from which RT will try to load the file main.css (which should @import any other files the stylesheet needs). This allows you to easily and cleanly create your own stylesheets to apply to RT. This option can be overridden by users in their preferences.

$RTSupportEmail

This is the email address of the person who administers and provides support for RT itself. If set, it is displayed on the RT login page and as such is likely to receive email from users who are unable to log in.

$ShowMobileSite

Starting with RT 5.0, RT's web interface is fully responsive and will render correctly on most mobile devices. However, RT also has a mobile-optimized mode that shows a limited feature set focused on ticket updates. To default to this site when RT is accessed from a mobile device, enable this option (set to 1).

$DefaultQueue

Use this to select the default queue name that will be used for creating new tickets. You may use either the queue's name or its ID. This only affects the queue selection boxes on the web interface.

$RememberDefaultQueue

When a queue is selected in the new ticket dropdown, make it the new default for the new ticket dropdown.

$EnableReminders

Hide all links and portlets related to Reminders by setting this to 0

@CustomFieldValuesSources

Set @CustomFieldValuesSources to a list of class names which extend RT::CustomFieldValues::External. This can be used to pull lists of custom field values from external sources at runtime.

@CustomFieldValuesCanonicalizers

Set @CustomFieldValuesCanonicalizers to a list of class names which extend RT::CustomFieldValues::Canonicalizer. This can be used to rewrite (canonicalize) values entered by users to fit some defined format.

See the documentation in RT::CustomFieldValues::Canonicalizer for adding your own canonicalizers.

%CustomFieldGroupings

This option affects the display of ticket, user, group, and asset custom fields in the web interface. It does not address the sorting of custom fields within the groupings; that ordering is controlled by the Ticket Custom Fields tab in Queue configuration in the Admin UI. Asset custom field ordering is found in the Asset Custom Fields tab in Catalog configuration.

A nested data structure defines how to group together custom fields under a mix of built-in and arbitrary headings ("groupings").

Set %CustomFieldGroupings to a nested structure similar to the following:

    Set(%CustomFieldGroupings,
        'RT::Ticket' => [
            'Grouping Name'     => ['CF Name', 'Another CF'],
            'Another Grouping'  => ['Some CF'],
            'Dates'             => ['Shipped date'],
        ],
        'RT::User' => [
            'Phones' => ['Fax number'],
        ],
        'RT::Asset' => [
            'Asset Details' => ['Serial Number', 'Manufacturer', 'Type', 'Tracking Number'],
            'Dates'         => ['Support Expiration', 'Issue Date'],
        ],
        'RT::Group' => [
            'Basics' => ['Department'],
        ],
    );

The first level keys are record types for which CFs may be used, and the values are either hashrefs or arrayrefs -- if arrayrefs, then the order of grouping entries is preserved during display, otherwise groupings are displayed alphabetically. The second level keys are the grouping names and the values are array refs containing a list of CF names.

For RT::Ticket and RT::Asset, you can specify global, and queue or catalog level groupings. For example, if you wanted to diplay some groupings only on tickets in the General queue, you can create an entry for 'General'. Global configurations then go in 'Default' as shown below.

    'RT::Ticket' => {
        'Default' => [
            'Grouping Name'    => [ 'CF Name' ],
        ],
        'General' => [
            'Grouping Name'    => [ 'CF Name', 'Another CF' ],
            'Another Grouping' => ['Some CF'],
            'Dates'            => ['Shipped date'],
        ],
    },

There are several special built-in groupings which RT displays in specific places (usually the collapsible box of the same title). The ordering of these standard groupings cannot be modified. You may also only append Custom Fields to the list in these boxes, not reorder or remove core fields.

For RT::Ticket, these groupings are: Basics, Dates, Links, People

For RT::User: Identity, Access control, Location, Phones

For RT::Group: Basics

For RT::Asset: Basics, Dates, People, Links

Extensions may also add their own built-in groupings, refer to the individual extension documentation for those.

$CanonicalizeRedirectURLs

Set $CanonicalizeRedirectURLs to 1 to use $WebURL when redirecting rather than the one we get from %ENV.

Apache's UseCanonicalName directive changes the hostname that RT finds in %ENV. You can read more about what turning it On or Off means in the documentation for your version of Apache.

If you use RT behind a reverse proxy, you almost certainly want to enable this option.

$CanonicalizeURLsInFeeds

Set $CanonicalizeURLsInFeeds to 1 to use $WebURL in feeds rather than the one we get from request.

If you use RT behind a reverse proxy, you almost certainly want to enable this option.

@JSFiles

A list of additional JavaScript files to be included in head.

@CSSFiles

A list of additional CSS files to be included in head.

If you're a plugin author, refer to RT->AddStyleSheets.

$UsernameFormat

This determines how user info is displayed. 'concise' will show the first of RealName, Name or EmailAddress that has a value. 'verbose' will show EmailAddress, and the first of RealName or Name which is defined. The default, 'role', uses 'verbose' for unprivileged users, and the Name followed by the RealName for privileged users.

$UserSearchResultFormat

This controls the display of lists of users returned from the User Summary Search. The display of users in the Admin interface is controlled by %AdminSearchResultFormat.

@UserSummaryPortlets

A list of portlets to be displayed on the User Summary page. By default, we show all of the available portlets. Extensions may provide their own portlets for this page.

$UserSummaryExtraInfo

This controls what information is displayed on the User Summary portal. By default the user's Real Name, Email Address and Username are displayed. You can remove these or add more as needed. This expects a Format string of user attributes. Please note that not all the attributes are supported in this display because we're not building a table.

$UserSummaryTicketListFormat

Control the appearance of the Active and Inactive ticket lists in the User Summary.

$WebBaseURL, $WebURL

Usually you don't want to set these options. The only obvious reason is if RT is accessible via https protocol on a non standard port, e.g. 'https://rt.example.com:9999'. In all other cases these options are computed using $WebDomain, $WebPort and $WebPath.

$WebBaseURL is the scheme, server and port (e.g. 'http://rt.example.com') for constructing URLs to the web UI. $WebBaseURL doesn't need a trailing /.

$WebURL is the $WebBaseURL, $WebPath and trailing /, for example: 'http://www.example.com/rt/'.

$WebImagesURL

$WebImagesURL points to the base URL where RT can find its images. Define the directory name to be used for images in RT web documents.

$LogoURL

$LogoURL points to the URL of the RT logo displayed in the web UI. This can also be configured via the web UI.

$LogoLinkURL

$LogoLinkURL is the URL that the RT logo hyperlinks to.

$LogoAltText

$LogoAltText is a string of text for the alt-text of the logo. It will be passed through loc for localization.

$WebNoAuthRegex

What portion of RT's URL space should not require authentication. The default is almost certainly correct, and should only be changed if you are extending RT.

$WebFlushDbCacheEveryRequest

By default, RT clears its database cache after every page view. This ensures that you've always got the most current information when working in a multi-process (mod_perl or FastCGI) Environment. Setting $WebFlushDbCacheEveryRequest to 0 will turn this off, which will speed RT up a bit, at the expense of a tiny bit of data accuracy.

%ChartFont

The GD module (which RT uses for graphs) ships with a built-in font that doesn't have full Unicode support. You can use a given TrueType font for a specific language by setting %ChartFont to (language => the absolute path of a font) pairs. Your GD library must have support for TrueType fonts to use this option. If there is no entry for a language in the hash then font with 'others' key is used.

RT comes with two TrueType fonts covering most available languages.

$ChartsTimezonesInDB

RT stores dates using the UTC timezone in the DB, so charts grouped by dates and time are not representative. Set $ChartsTimezonesInDB to 1 to enable timezone conversions using your DB's capabilities. You may need to do some work on the DB side to use this feature, read more in docs/customizing/timezones_in_charts.pod.

At this time, this feature only applies to MySQL and PostgreSQL.

@ChartColors

An array of 6-digit hexadecimal RGB color values used for chart series. By default there are 12 distinct colors.

$EnableJSChart

Set this to 0 to disable Chart in JavaScript.

$JSChartColorScheme

The color scheme to use for Chart in Javascript. By default it's brewer.Paired12. The full list is: https://nagix.github.io/chartjs-plugin-colorschemes/colorchart.html

Home page

$DefaultSummaryRows

$DefaultSummaryRows is default number of rows displayed in for search results on the front page.

@RefreshIntervals

This setting defines the possible homepage and search result refresh options. Each value is a number of seconds. You should not include a value of 0, as that is always provided as an option.

$HomePageRefreshInterval

$HomePageRefreshInterval is default number of seconds to refresh the RT home page. Choose from any value in "@RefreshIntervals", or the default of 0 for no automatic refresh.

$HomepageComponents

$HomepageComponents is an arrayref of allowed components on a user's customized homepage ("RT at a glance").

Ticket search

$UseSQLForACLChecks

Historically, ACLs were checked on display, which could lead to empty search pages and wrong ticket counts. Set $UseSQLForACLChecks to 0 to go back to this method; this will reduce the complexity of the generated SQL statements, at the cost of the aforementioned bugs.

$TicketsItemMapSize, $ShowSearchNavigation

On the display page of a ticket from search results, RT provides links to the first, next, previous and last ticket from the results. In order to build these links, RT needs to re-run the original search and fetch the full result set from the database. If the original search was resource-intensive, this will then slow down diplay of the ticket page.

Set $TicketsItemMapSize to the number of tickets you want RT to examine to build these links. If the full result set is larger than this number, RT will omit the "last" link in the menu. Set this to zero to always examine all results. This can improve performance for searches with large result sets.

Set $ShowSearchNavigation to 0 to not build these links at all and completely avoid re-running the original search query.

$SearchResultsRefreshInterval

$SearchResultsRefreshInterval is default number of seconds to refresh search results in RT. Choose from any value in "@RefreshIntervals", or the default of 0 for no automatic refresh.

$DefaultSearchResultFormat

$DefaultSearchResultFormat is the default format for RT search results

$UserTicketDataResultFormat

This is the format of ticket search result for "Download User Tickets" links. It defaults to DefaultSearchResultFormat for privileged users and DefaultSelfServiceSearchResultFormat for unprivileged users if it's not set.

$UserDataResultFormat

This is the format of the user search result for "Download User Data" links.

$UserTransactionDataResultFormat

This is the format of the user transaction search result for "Download User Transaction Data" links.

$DefaultSearchResultOrderBy

What Tickets column should we order by for RT Ticket search results.

$DefaultSearchResultOrder

When ordering RT Ticket search results by $DefaultSearchResultOrderBy, should the sort be ascending (ASC) or descending (DESC).

$ShowSearchResultCount

Display search result count on ticket lists. Defaults to 1 (show them).

%FullTextSearch

Full text search (FTS) without database indexing is a very slow operation, and is thus disabled by default.

Before setting Indexed to 1, read docs/full_text_indexing.pod for the full details of FTS on your particular database.

It is possible to enable FTS without database indexing support, simply by setting the Enable key to 1, while leaving Indexed set to 0. This is not generally suggested, as unindexed full-text searching can cause severe performance problems.

$MaxFulltextAttachmentSize

On some systems, very large attachments can cause memory and other performance issues for the indexer making it unable to complete indexing. Adding resources like memory and CPU will solve this issue, but in cases where that isn't possible, this option sets a maximum size in bytes on attachments to index. Attachments larger than this limit are skipped and will not be available to full text searches.

$DontSearchFileAttachments

If $DontSearchFileAttachments is set to 1, then uploaded files (attachments with file names) are not searched during content search.

Note that if you use indexed FTS then named attachments are still indexed by default regardless of this option.

$OnlySearchActiveTicketsInSimpleSearch

When query in simple search doesn't have status info, use this to only search active ones.

$SearchResultsAutoRedirect

When only one ticket is found in search, use this to redirect to the ticket display page automatically.

$InlineEdit

Allows users to update tickets directly on search results and ticket display pages.

%InlineEditPanelBehavior

This setting allows you to control which panels on display pages participate in inline edit, as well as fine-tuning their specific behavior.

Much like "%CustomFieldGroupings", you first specify a record type you want to configure (though since currently only ticket display supports inline edit, keys besides RT::Ticket are ignored). Then, for each panel, you specify its behavior. The valid behaviors are:

link (the default)

The panel will have an "Edit" link in the top right, which when clicked immediately activates inline edit. The "Edit" link will change to "Cancel" to restore the readonly display.
click

Much like link, except you may click anywhere inside the panel to activate inline edit.
hide

Turns off inline edit entirely for this panel.
always

Turns off the readonly display for this panel, providing only inline edit capabilities.

You may also provide the special key _default inside a record type to specify a default behavior for all panels.

This sample configuration will provide a default inline edit behavior of click, but also specifies different behaviors for several other panels. Note that the non-standard panel names "Grouping Name" and "Another Grouping" are created by the "%CustomFieldGroupings" setting.

    Set(%InlineEditPanelBehavior,
        'RT::Ticket' => {
            '_default'          => 'click',

            'Grouping Name'     => 'link',
            'Another Grouping'  => 'click',
            'Dates'             => 'always',
            'Links'             => 'hide',
            'People'            => 'link',
        },
    );

Ticket options

$DisplayTotalTimeWorked

Set to 1 to display Total Time Worked in the Basics section.

Total Time Worked is a dynamic value containing a sum of Time Worked for the parent and all child tickets. This value is generated when displaying the ticket and automatically updates when a child ticket is added or removed. Total Time Worked follows only parent/child link relationships. Tickets linked with depends-on or refers-to links are not included.

Total Time Worked is also available as a column for reports generated with the Query Builder.

$ShowMoreAboutPrivilegedUsers

This determines if the 'More about requestor' box on Ticket/Display.html is shown for Privileged Users.

$MoreAboutRequestorTicketList

This can be set to Active, Inactive, All or None. It controls what ticket list will be displayed in the 'More about requestor' box on Ticket/Display.html. This option can be controlled by users also.

$MoreAboutRequestorTicketListFormat

Control the appearance of the ticket lists in the 'More About Requestors' box.

$MoreAboutRequestorExtraInfo

By default, the 'More about requestor' box on Ticket/Display.html shows the Requestor's name and ticket list. If you would like to see extra information about the user, this expects a Format string of user attributes. Please note that not all the attributes are supported in this display because we're not building a table.

Example: Set($MoreAboutRequestorExtraInfo,"Organization, Address1")

$MoreAboutRequestorGroupsLimit

By default, the 'More about requestor' box on Ticket/Display.html shows all the groups of the Requestor. Use this to limit the number of groups; a value of undef removes the group display entirely.

$UseSideBySideLayout

Should the ticket create and update forms use a more space efficient two column layout. This layout may not work in narrow browsers if you set a MessageBoxWidth (below).

$EditCustomFieldsSingleColumn

When displaying a list of Ticket Custom Fields for editing, RT defaults to a 2 column list. If you set this to 1, it will instead display the Custom Fields in a single column.

$ShowUnreadMessageNotifications

If set to 1, RT will prompt users when there are new, unread messages on tickets they are viewing.

$AutocompleteOwners

If set to 1, the owner drop-downs for ticket update/modify and the query builder are replaced by text fields that autocomplete. This can alleviate the sometimes huge owner list for installations where many users have the OwnTicket right.

The Owner entry is automatically converted to an autocomplete box if the list of owners exceeds $DropdownMenuLimit items. However, the query to generate the list of owners is still run and this can increase page load times. If your owner lists exceed the limit and you are using the autocomplete box, you can improve performance by explicitly setting $AutocompleteOwners.

Drop down doesn't show unprivileged users. If your setup allows unprivileged to own ticket then you have to enable autocompleting.

$DropdownMenuLimit

The Owner dropdown menu, used in various places in RT including the Query Builder and ticket edit pages, automatically changes from a dropdown menu to an autocomplete field once the menu holds more than the $DropdownMenuLimit owners. Dropdown menus become more difficult to use when they contain a large number of values and the autocomplete textbox can be more usable.

If you have very large numbers of users who can be owners, this can cause slow page loads on pages with an Owner selection. See "$AutocompleteOwners" for a way to potentially speed up page loads.

$AutocompleteOwnersForSearch

If set to 1, the owner drop-downs for the query builder are always replaced by text field that autocomplete and $AutocompleteOwners is ignored. Helpful when owners list is huge in the query builder.

$AutocompleteQueues

If set to 1, any queue drop-downs are replaced by text fields that autocomplete. This can alleviate the sometimes huge queue list for installations with many queues, and can also increase page load times in some cases. A user can override this setting as a personal preference.

$ArticleSearchFields

Used when searching for an Article to Include.

Specifies which fields of RT::Article to match against and how to match each field when autocompleting articles. Valid match methods are LIKE, STARTSWITH, ENDSWITH, =, and !=. Valid search fields are the core Article fields, as well as custom fields, including Content, which are specified as "CF.1234" or "CF.Name"

$UserSearchFields

Used by the User Autocompleter as well as the User Search.

Specifies which fields of RT::User to match against and how to match each field when autocompleting users. Valid match methods are LIKE, STARTSWITH, ENDSWITH, =, and !=. Valid search fields are the core User fields, as well as custom fields, which are specified as "CF.1234" or "CF.Name"

$TicketAutocompleteFields

Specifies which fields of RT::Ticket to match against and how to match each field when autocompleting users. Valid match methods are LIKE, STARTSWITH, ENDSWITH, =, and !=.

Not all Ticket fields are publically accessible and hence won't work for autocomplete unless you override their accessibility using a local overlay or a plugin. Out of the box the following fields are public: id, Subject.

$DisplayTicketAfterQuickCreate

Enable this to redirect to the created ticket display page automatically when using QuickCreate.

$WikiImplicitLinks

Support implicit links in WikiText custom fields? Setting this to 1 causes InterCapped or ALLCAPS words in WikiText fields to automatically become links to searches for those words. If used on Articles, it links to the Article with that name.

%LinkedQueuePortlets

%LinkedQueuePortlets allows you to display links to tickets in another queue in a stand-alone portlet on the ticket display page. This makes it easier to highlight specific ticket links separate from the standard Links portlet.

For example, you might have a Sales queue that tracks incoming product requests, and for each ticket you create a linked ticket in the Shipping queue for each outgoing shipment. You could add the configuration below to create a stand-alone Shipping portlet on tickets in the Sales queue, making it easier to see those linked tickets. You might have a Returns queue to show as well.

    Set( %LinkedQueuePortlets, (
        'Sales' => [
            { 'Shipping'   => [ 'All' ] },
            { 'Returns'   => [ 'RefersTo' ] },
        ],
        'Shipping'   => [
            { 'Postage' => [ 'DependsOn', 'HasMember' ] },
        ],
    ));

You can include multiple linked queues in each ticket and they are displayed in the order you define them in the configuration. The values are RT link types: 'DependsOn', 'DependedOnBy', 'HasMember' (children), 'MemberOf' (parents), 'RefersTo', and 'ReferredToBy'. 'All' lists all linked tickets. You can include multiple link types for each as shown above.

%LinkedQueuePortletFormats

%LinkedQueuePortletFormats defines the format for displaying linked tickets in each linked queue portlet defined by %LinkedQueuePortlets.

To change just the General list you would do:

    Set(%LinkedQueuePortletFormats, General => 'modified configuration');

$PreviewScripMessages

Set $PreviewScripMessages to 1 if the scrips preview on the ticket reply page should include the content of the messages to be sent.

$SimplifiedRecipients

If $SimplifiedRecipients is set, a simple list of who will receive any kind of mail will be shown on the ticket reply page, instead of a detailed breakdown by scrip.

$SquelchedRecipients

If $SquelchedRecipients is set, the checkbox list of who will receive any kind of mail on the ticket reply page are displayed initially as unchecked - which means nobody in that list would get any mail. It does not affect correspondence done via email yet.

$HideResolveActionsWithDependencies

If set to 1, this option will skip ticket menu actions which can't be completed successfully because of outstanding active Depends On tickets.

By default, all ticket actions are displayed in the menu even if some of them can't be successful until all Depends On links are resolved or transitioned to another inactive status.

$HideUnsetFieldsOnDisplay

This determines if we should hide unset fields on ticket display page. Set this to 1 to hide unset fields.

$HideOneTimeSuggestions

On ticket comment and correspond there are "One-time Cc" and "One-time Bcc" fields. As part of this section, RT includes a list of suggested email addresses based on the correspondence history for that ticket. This list may grow quite large over time.

Enabling this option will hide the list behind a "(show suggestions)" link to cut down on page clutter. Once this option is clicked the link will change to "(hide suggestions)" and the full list of email addresses will be shown.

$EnablePriorityAsString

Priority is stored as a number internally. This determines whether Priority is displayed to users as a number or using configured labels like Low, Medium, High. See %PriorityAsString for details on this configuration.

The default is enabled, so strings are shown. Set to 0 to display numbers, which was the previous default for RT.

%PriorityAsString

This setting allows you to define labels for priority values available on tickets. RT stores these values internally as a number, but this number will be hidden if $EnablePriorityAsString is true. For the configuration, link the labels to numbers as shown below. If you have more or less priority settings, you can adjust the numbers, giving a unique number to each.

    Set(%PriorityAsString,
        Default => { Low => 0, Medium => 50, High => 100 },
        General => [ Medium => 50, Low => 0, High => 80, 'On Fire' => 100],
        Support => 0,
    );

The key is queue name or "Default", which is the fallback for unspecified queues. Values can be an ArrayRef, HashRef, or 0.

ArrayRef: This is the ordered String => Number map list. Pririty options will be rendered in the order they are listed in the list.
HashRef: This is the unordered String => Number map list. Priority options will be rendered in numerical ascending order.
0: Priority is rendered as a number.

Group Summary Configuration

Below are configuration options for the Group Summary page.

$GroupSearchResultFormat: This controls the display of lists of groups returned from the Group Summary Search. The display of groups in the Admin interface is controlled by %AdminSearchResultFormat.
@GroupSummaryPortlets: A list of portlets to be displayed on the Group Summary page. By default, we show all of the available portlets. Extensions may provide their own portlets for this page.
$GroupSummaryExtraInfo: This controls what information is displayed on the Group Summary portal. By default the group Name and Description are displayed.
$GroupSummaryTicketListFormat: Control the appearance of the Active and Inactive ticket lists in the Group Summary.
$GroupSearchFields: Specifies which fields of RT::Group to match against and how to match each field when performing a quick search on groups. Valid match methods are LIKE, STARTSWITH, ENDSWITH, =, and !=. Valid search fields are id, Name, Description, or custom fields, which are specified as "CF.1234" or "CF.Name"
$AllowGroupAutocompleteForUnprivileged: Defines whether unprivileged users (users of SelfService) are allowed to autocomplete groups when searching. Setting this option to 1 means unprivileged users will be able to search all your user created group names. Users will also need the SeeGroup privilege to use this feature.

Self Service Interface

The Self Service Interface is a view automatically presented to Unprivileged users who have a password and log into the web UI. The following options modify the default behavior of the Self Service pages.

$SelfServiceCorrespondenceOnly

On the ticket display page, show only correspondence transactions in the ticket history. This hides all ticket update transactions like status changes, custom field updates, updates to watchers, etc.

$HideTimeFieldsFromUnprivilegedUsers

This determines if we should hide Time Worked, Time Estimated, and Time Left for unprivileged users. Set this to 1 to hide those fields.

$AllowUserAutocompleteForUnprivileged

Should unprivileged users (users of SelfService) be allowed to autocomplete users. Setting this option to 1 means unprivileged users will be able to search all your users.

$DefaultSelfServiceSearchResultFormat

$DefaultSelfServiceSearchResultFormat is the default format of searches displayed in the SelfService interface.

$SelfServiceRegex

What portion of RT's URLspace should be accessible to Unprivileged users This does not override the redirect from /Ticket/Display.html to /SelfService/Display.html when Unprivileged users attempt to access ticked displays.

$SelfServiceUserPrefs

This option controls how the SelfService user preferences page is displayed. It accepts a string from one of the four possible modes below.

edit-prefs (the default): When set to edit-prefs, self service users will be able to update their Timezone and Language preference and update their password. This is the default behavior of RT.
view-info: When set to view-info, users will have full access to all their user information stored in RT on a read-only page.
edit-prefs-view-info: When set to edit-prefs-view-info, users will have full access as in the view-info option, but also will be able to update their Locale and password as in the default edit-prefs option.
full-edit: When set to full-edit, users will be able to fully view and update all of their stored RT user information.

$SelfServiceRequestUpdateQueue

Set this to the name of the queue to use for tickets requesting updates to user infomation from Self Service users. Once it's set, a quick ticket create portlet will show up on Preferences page for self service users. This option is only available when $SelfServiceUserPrefs is set to 'view-info' or 'edit-prefs-view-info'.

Self service users need the CreateTicket right on this queue to create a ticket.

$SelfServiceDownloadUserData

Allow Self Service users to download their user information, ticket data, and transaction data as a .tsv file. When enabled, these options will appear in the self service interface at Logged in as > Preferences. Users also need the ModifySelf right to have access to this page.

$SelfServiceShowGroupTickets

Set this option to true to show a section with group tickets on self service pages.

$SelfServiceUseDashboard

$SelfServiceUseDashboard is a flag indicating whether or not to use a dashboard for the Self Service home page. If it is set to false, then the normal Open Tickets / Closed Tickets menu is shown rather than a dashboard.

$SelfServicePageComponents

$SelfServicePageComponents is an arrayref of allowed components on the SelfService page, if you have set $SelfServiceUseDashboard to true.

$SelfServiceShowArticleSearch

If enabled, $SelfServiceShowArticleSearch displays a "Search Articles" box in the menu bar in the self service interface. This option controls only showing or hiding the search box. Users still need appropriate rights to see article search results and view articles.

Articles

$ArticleOnTicketCreate: Set this to 1 to display the Articles interface on the Ticket Create page in addition to the Reply/Comment page.
$HideArticleSearchOnReplyCreate: Set this to 1 to hide "Include Article" box on the ticket update page.
$LinkArticlesOnInclude: Set this to 0 to suppress the default behavior of automatically linking to Articles when they are included in a message.

Assets

@AssetQueues

This should be a list of names of queues whose tickets should always display the "Assets" box. This is useful for queues which deal primarily with assets, as it provides a ready box to link an asset to the ticket, even when the ticket has no related assets yet.

$DefaultCatalog

This provides the default catalog after a user initially logs in. However, the default catalog is "sticky," and so will remember the last-selected catalog thereafter.

$AssetSearchFields

Specifies which fields of RT::Asset to match against and how to match each field when performing a quick search on assets. Valid match methods are LIKE, STARTSWITH, ENDSWITH, =, and !=. Valid search fields are id, Name, Description, or custom fields, which are specified as "CF.1234" or "CF.Name"

$AssetDefaultSearchResultFormat

The format that results of the asset search are displayed with.

$AssetDefaultSearchResultOrderBy

What column should we order by for RT asset search results.

$AssetDefaultSearchResultOrder

When ordering asset search results by $AssetDefaultSearchResultOrderBy, should the sort be ascending (ASC) or descending (DESC).

$AssetShowSearchResultCount

Display search result count on asset lists. Defaults to 1 (show them).

$AssetSimpleSearchFormat

The format that results of the asset simple search are displayed with. This is either a string, which will be used for all catalogs, or a hash reference, keyed by catalog's name/id. If a hashref and neither name or id is found therein, falls back to the key ''.

If you wish to use the multiple catalog format, your configuration would look something like:

    Set($AssetSimpleSearchFormat, {
        'General assets' => q[Format String for the General Assets Catalog],
        8                => q[Format String for Catalog 8],
        ''               => q[Format String for any catalogs not listed explicitly],
    });

$AssetSummaryFormat

The information that is displayed on ticket display pages about assets related to the ticket. This is displayed in a table beneath the asset name.

$AssetSummaryRelatedTicketsFormat

The information that is displayed on ticket display pages about tickets related to assets related to the ticket. This is displayed as a list of tickets underneath the asset properties.

$AssetBasicCustomFieldsOnCreate

Specify a list of Asset custom fields to show in "Basics" widget on create.

e.g.

Set( $AssetBasicCustomFieldsOnCreate, [ 'foo', 'bar' ] );

$AssetHideSimpleSearch

Set to a true value to hide the legacy Asset Simple Search in favor of AssetSQL added in RT 5.0.

When hidden, the Asset search menu shows the Current Search menu like tickets, giving quick access back to a search after clicking on an asset.

$AssetMultipleOwner

By default an asset is limited to a single user as an owner. By setting this to a true value, you can allow multiple users and groups as owner. If you change this back to a false value while having multiple owners set on any assets, RT's behavior may be inconsistent.

$UserAssetExtraInfo

By default the People portlet on the asset display page shows the Name field for each user. Set this value with additional fields from the user record to show more information about the users. The value is a Format string of user attributes or custom fields. For example, to show the user's email, city, state, zip, and the user custom field Primary Office:

    Set($UserAssetExtraInfo, 'EmailAddress, City, State, Zip, "CF.{Primary Office}"');

Message box properties

$MessageBoxWidth, $MessageBoxHeight

For message boxes, set the entry box width, height and what type of wrapping to use. These options can be overridden by users in their preferences.

When the width is set to undef, no column count is specified and the message box will take up 100% of the available width. Combining this with HARD messagebox wrapping (below) is not recommended, as it will lead to inconsistent width in transactions between browsers.

These settings only apply to the non-RichText message box. See below for Rich Text settings.

$MessageBoxRichText

Should "rich text" editing be enabled? This option lets your users send HTML email messages from the web interface.

$MessageBoxRichTextHeight

Height of rich text JavaScript enabled editing boxes (in pixels)

$MessageBoxIncludeSignature

Should your users' signatures (from their Preferences page) be included in Comments and Replies.

$MessageBoxIncludeSignatureOnComment

Should your users' signatures (from their Preferences page) be included in Comments. Setting this to 0 overrides $MessageBoxIncludeSignature.

$SignatureAboveQuote

By default RT places the signature at the bottom of the quoted text in the message box for ticket replies. Set this to 1 to place the signature above the quoted text.

Attach Files

$PreferDropzone: By default, RT uses Dropzone to attach files if possible. If $PreferDropzone is set to 0, RT will always use plain file inputs.

Transaction search

%TransactionDefaultSearchResultFormat

%TransactionDefaultSearchResultFormat is the default format for RT transaction search results for various object types. Keys are object types like RT::Ticket, values are the format string.

%TransactionDefaultSearchResultOrderBy

What Transactions column should we order by for RT Transaction search results for various object types. Keys are object types like RT::Ticket, values are the column names.

Defaults to id.

%TransactionDefaultSearchResultOrder

When ordering RT Transaction search results by %TransactionDefaultSearchResultOrderBy, should the sort be ascending (ASC) or descending (DESC). Keys are object types like RT::Ticket, values are either "ASC" or "DESC".

Defaults to ASC.

%TransactionShowSearchResultCount

Display search result count on transaction lists. Keys are object types like RT::Ticket, values are either 1 or 0.

Defaults to 1 (show them).

Transaction display

$OldestTransactionsFirst

By default, RT shows newest transactions at the bottom of the ticket history page, if you want see them at the top set this to 0. This option can be overridden by users in their preferences.

$ShowHistory

This option controls how history is shown on the ticket display page. It accepts one of three possible modes and is overrideable on a per-user preference level. If you regularly deal with long tickets and don't care much about the history, you may wish to change this option to click.

delay (the default): When set to delay, history is loaded via javascript after the rest of the page has been loaded. This speeds up apparent page load times and generally provides a smoother experience. You may notice slight delays before the ticket history appears on very long tickets.
click: When set to click, history is loaded on demand when a placeholder link is clicked. This speeds up ticket display page loads and history is never loaded if not requested.
always: When set to always, history is loaded before showing the page. This ensures history is always available immediately, but at the expense of longer page load times. This behaviour was the default in RT 4.0.
scroll: When set to scroll, history is loaded via javascript after the rest of the page has been loaded, as you scroll down the page. Ten transactions are loaded initially, and then more are loaded ten at a time. This can dramatically speed up initial page load times on very long tickets.

$ShowBccHeader

By default, RT hides from the web UI information about blind copies user sent on reply or comment.

$TrustHTMLAttachments

If TrustHTMLAttachments is not defined, we will display them as text. This prevents malicious HTML and JavaScript from being sent in a request (although there is probably more to it than that)

$AlwaysDownloadAttachments

Always download attachments, regardless of content type. If set, this overrides TrustHTMLAttachments.

$AttachmentListCount

Sets the number of attachments to display on ticket display and ticket update pages (default is 5). Attachments beyond this number are displayed only after the user clicks the "Show all" link. Set to undef to always show all attachments. A value of 0 means show no attachments by default.

$PreferRichText

By default, RT shows rich text (HTML) messages if possible. If $PreferRichText is set to 0, RT will show plain text messages in preference to any rich text alternatives.

As a security precaution, RT limits the HTML that is displayed to a known-good subset -- as allowing arbitrary HTML to be displayed exposes multiple vectors for XSS and phishing attacks. If "$TrustHTMLAttachments" is enabled, the original HTML is available for viewing via the "Download" link.

$MaxInlineBody

$MaxInlineBody is the maximum textual attachment size that we want to see inline when viewing a transaction. RT will inline any text if the value is undefined or 0. This option can be overridden by users in their preferences. The default is 25k.

$ShowTransactionImages

By default, RT shows images attached to incoming (and outgoing) ticket updates inline. Set this variable to 0 if you'd like to disable that behavior.

$ShowRemoteImages

By default, RT doesn't show remote images attached to incoming (and outgoing) ticket updates inline. Set this variable to 1 if you'd like to enable remote image display. Showing remote images may allow spammers and other senders to track when messages are viewed and see referer information.

Note that this setting is independent of "$ShowTransactionImages" above.

$PlainTextMono

Normally plaintext attachments are displayed as HTML with line breaks preserved. This causes space- and tab-based formatting not to be displayed correctly. Set $PlainTextMono to 1 to use a monospaced font and preserve formatting.

$SuppressInlineTextFiles

If $SuppressInlineTextFiles is set to 1, then uploaded text files (text-type attachments with file names) are prevented from being displayed in-line when viewing a ticket's history.

@Active_MakeClicky

MakeClicky detects various formats of data in headers and email messages, and extends them with supporting links. By default, RT provides two formats:

* 'httpurl': detects http:// and https:// URLs and adds '[Open URL]' link after the URL.

* 'httpurl_overwrite': also detects URLs as 'httpurl' format, but replaces the URL with a link. Enabled by default.

See share/html/Elements/MakeClicky for documentation on how to add your own styles of link detection.

$QuoteFolding

Quote folding is the hiding of old replies in transaction history. It defaults to on. Set this to 0 to disable it.

$QuoteWrapWidth

$QuoteWrapWidth controls the number of columns to use when wrapping quoted text within transactions.

Administrative interface

$ShowRTPortal

RT can show administrators a feed of recent RT releases and other related announcements and information from Best Practical on the top level Admin page. This feature helps you stay up to date on RT security announcements and version updates.

RT provides this feature using an "iframe" on /Admin/index.html which asks the administrator's browser to show an inline page from Best Practical's website.

If you'd rather not make this feature available to your administrators, set $ShowRTPortal to 0.

%AdminSearchResultFormat

In the admin interface, format strings similar to tickets result formats are used. Use %AdminSearchResultFormat to define the format strings used in the admin interface on a per-RT-class basis.

%AdminSearchResultRows

Use %AdminSearchResultRows to define the search result rows in the admin interface on a per-RT-class basis.

$ShowEditSystemConfig

Starting in RT 5.0, SuperUsers can edit RT system configuration via the web UI. Options set in the web UI take precedence over those set in configuration files.

If you prefer to set configuration only via files, set $ShowEditSystemConfig to 0 to disable the web UI editing interface.

$ShowEditLifecycleConfig

Starting in RT 5.0, SuperUsers can edit lifecycle configuration via the web UI. Options set in the web UI take precedence over those set in configuration files.

Set $ShowEditLifecycleConfig to 0 to disable the web UI editing interface.

Features

Syncing Users and Groups with LDAP or AD

In addition to the authentication services described above, RT also has a utility you can schedule to periodicially sync from your directory service additional user attributes, new users, disabled users, and group membership. Options for the LDAPImport tool are listed here. Additional information is available in the RT::LDAPImport documentation.

$LDAPHost

Your LDAP server hostname.

$LDAPUser

The LDAP user to log in with.

$LDAPOptions

LDAP options that are supported by the Net::LDAP new method.

Example:

    Set($LDAPOptions, [ port => 636 ]);

$LDAPPassword

Password for LDAPUser.

$LDAPBase

The LDAP search base.

Example:

    Set($LDAPBase, 'ou=Organisational Unit,dc=domain,dc=TLD');

$LDAPFilter

The filter to use when querying LDAP for the set of users to sync.

$LDAPMapping

Mapping to apply between LDAP attributes retrieved and RT user record attributes. See the RT::LDAPImport documentation for details.

$LDAPGroupBase

The base for the LDAP group search.

$LDAPGroupFilter

The filter to use when querying LDAP for groups to sync.

$LDAPGroupMapping

Mapping to apply between LDAP group member attributes retrieved and RT groups. See the RT::LDAPImport documentation for details.

Cryptography

A complete description of RT's cryptography capabilities can be found in RT::Crypt. At this moment, GnuPG (PGP) and SMIME security protocols are supported.

%Crypt

The following options apply to all cryptography protocols.

By default, all enabled security protocols will analyze each incoming email. You may set Incoming to a subset of this list, if some enabled protocols do not apply to incoming mail; however, this is usually unnecessary.

For outgoing emails, the first security protocol from the above list is used. Use the Outgoing option to set a security protocol that should be used in outgoing emails. At this moment, only one protocol can be used to protect outgoing emails.

Set RejectOnMissingPrivateKey to 0 if you don't want to reject emails encrypted for key RT doesn't have and can not decrypt.

Set RejectOnBadData to 0 if you don't want to reject letters with incorrect data.

If you want to allow people to encrypt attachments inside the DB then set AllowEncryptDataInDB to 1.

Set Dashboards to a hash with Encrypt and Sign keys to control whether dashboards should be encrypted and/or signed correspondingly. By default they are not encrypted or signed.

Similarly, set DigestEmail to a hash with Encrypt and Sign keys to control whether digest email should be encrypted and/or signed. By default they are not encrypted or signed.

SMIME configuration

A full description of the SMIME integration can be found in RT::Crypt::SMIME.

%SMIME

Set Enable to 0 or 1 to disable or enable SMIME for encrypting and signing messages.

Set OpenSSL to path to openssl executable.

Set Keyring to directory with key files. Key and certificates should be stored in a PEM file in this directory named named, e.g., email.address@example.com.pem.

Set CAPath to either a PEM-formatted certificate of a single signing certificate authority, or a directory of such (including hash symlinks as created by the openssl tool c_rehash). Only SMIME certificates signed by these certificate authorities will be treated as valid signatures. If left unset (and AcceptUntrustedCAs is unset, as it is by default), no signatures will be marked as valid!

Set AcceptUntrustedCAs to allow arbitrary SMIME certificates, no matter their signing entities. Such mails will be marked as untrusted, but signed; CAPath will be used to mark which mails are signed by trusted certificate authorities. This configuration is generally insecure, as it allows the possibility of accepting forged mail signed by an untrusted certificate authority.

Setting AcceptUntrustedCAs also allows encryption to users with certificates created by untrusted CAs.

Set Passphrase to a scalar (to use for all keys), an anonymous function, or a hash (to look up by address). If the hash is used, the '' key is used as a default.

Set OtherCertificatesToSend to path to a PEM-formatted certificate file. Certificates in the file will be include in outgoing signed emails.

Set CheckCRL to a true value to have RT check for revoked certificates by downloading a CRL. By default, CheckCRL is disabled.

Set CheckOCSP to a true value to have RT check for revoked certificates against an OCSP server if possible. By default, CheckOCSP is disabled.

Set CheckRevocationDownloadTimeout to the timeout in seconds for downloading a CRL or an issuer certificate (the latter is used when checking against OCSP). The default timeout is 30 seconds.

See RT::Crypt::SMIME for details.

GnuPG configuration

A full description of the (somewhat extensive) GnuPG integration can be found by running the command `perldoc RT::Crypt::GnuPG` (or `perldoc lib/RT/Crypt/GnuPG.pm` from your RT install directory).

%GnuPG

Set Enable to 0 or 1 to disable or enable GnuPG interfaces for encrypting and signing outgoing messages.

Set GnuPG to the name or path of the gpg binary to use.

Set Passphrase to a scalar (to use for all keys), an anonymous function, or a hash (to look up by address). If the hash is used, the '' key is used as a default.

Set OutgoingMessagesFormat to 'inline' to use inline encryption and signatures instead of 'RFC' (GPG/MIME: RFC3156 and RFC1847) format.

Plain (not encrypted) email sent to RT can have attached files that are encrypted. Set FileExtensions to any file extensions on attachments that RT should treat as encrypted and attempt to decrypt with gpg.

%GnuPGOptions

Options to pass to the GnuPG program.

If you override this in your RT_SiteConfig, you should be sure to include a homedir setting.

Note that options with '-' character MUST be quoted.

External storage

By default, RT stores attachments in the database. ExternalStorage moves all attachments that RT does not need efficient access to (which include textual content and images) to outside of the database. This may either be on local disk, or to a cloud storage solution. This decreases the size of RT's database, in turn decreasing the burden of backing up RT's database, at the cost of adding additional locations which must be configured or backed up. Attachment storage paths are calculated based on file contents; this provides de-duplication.

A full description of external storage can be found by running the command `perldoc RT::ExternalStorage` (or `perldoc lib/RT/ExternalStorage.pm` from your RT install directory).

Note that simply configuring RT::ExternalStorage is insufficient; there are additional steps required (including setup of a regularly-scheduled upload job) to enable RT to make use of external storage.

%ExternalStorage

This selects which storage engine is used, as well as options for configuring that specific storage engine. RT ships with the following storage engines:

RT::ExternalStorage::Disk, which stores files on directly onto disk.

RT::ExternalStorage::AmazonS3, which stores files on Amazon's S3 service.

RT::ExternalStorage::Dropbox, which stores files in Dropbox.

See each storage engine's documentation for the configuration it requires and accepts.

    Set(%ExternalStorage,
        Type => 'Disk',
        Path => '/opt/rt5/var/attachments',
    );

$ExternalStorageCutoffSize

Certain object types, like values for Binary (aka file upload) custom fields, are always put into external storage. However, for other object types, like images and text, there is a line in the sand where you want small objects in the database but large objects in external storage. By default, objects larger than 10 MiB will be put into external storage. $ExternalStorageCutoffSize adjusts that line in the sand.

Note that changing this setting does not affect existing attachments, only the new ones that sbin/rt-externalize-attachments hasn't seen yet.

$ExternalStorageDirectLink

Certain ExternalStorage backends can serve files over HTTP. For such backends, RT can link directly to those files in external storage. This cuts down download time and relieves resource pressure because RT's web server is no longer involved in retrieving and then immediately serving each attachment.

Of the storage engines that RT ships, only RT::ExternalStorage::AmazonS3 supports this feature, and you must manually configure it to allow direct linking.

Set this to 1 to link directly to files in external storage.

Lifecycles

Lifecycle definitions

Each lifecycle is a list of possible statuses split into three logic sets: initial, active and inactive. Each status in a lifecycle must be unique. (Statuses may not be repeated across sets.) Each set may have any number of statuses.

For example:

    default => {
        initial  => ['new'],
        active   => ['open', 'stalled'],
        inactive => ['resolved', 'rejected', 'deleted'],
        ...
    },

Status names can be from 1 to 64 ASCII characters. Statuses are localized using RT's standard internationalization and localization system.

initial

You can define multiple initial statuses for tickets in a given lifecycle.

RT will automatically set its Started date when you change a ticket's status from an initial state to an active or inactive status.

active

Active tickets are "currently in play" - they're things that are being worked on and not yet complete.

inactive

Inactive tickets are typically in their "final resting state".

While you're free to implement a workflow that ignores that description, typically once a ticket enters an inactive state, it will never again enter an active state.

RT will automatically set the Resolved date when a ticket's status is changed from an Initial or Active status to an Inactive status.

deleted is still a special status and protected by the DeleteTicket right, unless you re-defined rights (read below). If you don't want to allow ticket deletion at any time simply don't include it in your lifecycle.

Statuses in each set are ordered and listed in the UI in the defined order.

Changes between statuses are constrained by transition rules, as described below.

Default values

In some cases a default value is used to display in UI or in API when value is not provided. You can configure defaults using the following syntax:

    default => {
        ...
        defaults => {
            on_create => 'new',
            on_resolve => 'resolved',
            ...
        },
    },

The following defaults are used.

on_create: If you (or your code) doesn't specify a status when creating a ticket, RT will use the this status. See also "Statuses available during ticket creation".
approved: When an approval is accepted, the status of depending tickets will be changed to this value.
denied: When an approval is denied, the status of depending tickets will be changed to this value.
reminder_on_open: When a reminder is opened, the status will be changed to this value.
reminder_on_resolve: When a reminder is resolved, the status will be changed to this value.

Transitions between statuses and UI actions

A Transition is a change of status from A to B. You should define all possible transitions in each lifecycle using the following format:

    default => {
        ...
        transitions => {
            ''       => [qw(new open resolved)],
            new      => [qw(open resolved rejected deleted)],
            open     => [qw(stalled resolved rejected deleted)],
            stalled  => [qw(open)],
            resolved => [qw(open)],
            rejected => [qw(open)],
            deleted  => [qw(open)],
        },
        ...
    },

The order of items in the listing for each transition line affects the order they appear in the drop-down. If you change the config for 'open' state listing to:

    open     => [qw(stalled rejected deleted resolved)],

then the 'resolved' status will appear as the last item in the drop-down.

Statuses available during ticket creation

By default users can create tickets with a status of new, open, or resolved, but cannot create tickets with a status of rejected, stalled, or deleted. If you want to change the statuses available during creation, update the transition from '' (empty string), like in the example above.

Protecting status changes with rights

A transition or group of transitions can be protected by a specific right. Additionally, you can name new right names, which will be added to the system to control that transition. For example, if you wished to create a lesser right than ModifyTicket for rejecting tickets, you could write:

    default => {
        ...
        rights => {
            '* -> deleted'  => 'DeleteTicket',
            '* -> rejected' => 'RejectTicket',
            '* -> *'        => 'ModifyTicket',
        },
        ...
    },

This would create a new RejectTicket right in the system which you could assign to whatever groups you choose.

On the left hand side you can have the following variants:

    '<from> -> <to>'
    '* -> <to>'
    '<from> -> *'
    '* -> *'

Valid transitions are listed in order of priority. If a user attempts to change a ticket's status from new to open then the lifecycle is checked for presence of an exact match, then for 'any to open', 'new to any' and finally 'any to any'.

If you don't define any rights, or there is no match for a transition, RT will use the DeleteTicket or ModifyTicket as appropriate.

Labeling and defining actions

For each transition you can define an action that will be shown in the UI; each action annotated with a label and an update type.

Each action may provide a default update type, which can be Comment, Respond, or absent. For example, you may want your staff to write a reply to the end user when they change status from new to open, and thus set the update to Respond. Neither Comment nor Respond are mandatory, and user may leave the message empty, regardless of the update type.

This configuration can be used to accomplish what $ResolveDefaultUpdateType was used for in RT 3.8.

Use the following format to define labels and actions of transitions:

    default => {
        ...
        actions => [
            'new -> open'     => { label => 'Open it', update => 'Respond' },
            'new -> resolved' => { label => 'Resolve', update => 'Comment' },
            'new -> rejected' => { label => 'Reject',  update => 'Respond' },
            'new -> deleted'  => { label => 'Delete' },

            'open -> stalled'  => { label => 'Stall',   update => 'Comment' },
            'open -> resolved' => { label => 'Resolve', update => 'Comment' },
            'open -> rejected' => { label => 'Reject',  update => 'Respond' },

            'stalled -> open'  => { label => 'Open it' },
            'resolved -> open' => { label => 'Re-open', update => 'Comment' },
            'rejected -> open' => { label => 'Re-open', update => 'Comment' },
            'deleted -> open'  => { label => 'Undelete' },
        ],
        ...
    },

In addition, you may define multiple actions for the same transition. Alternately, you may use '* -> x' to match more than one transition. For example:

    default => {
        ...
        actions => [
            ...
            'new -> rejected' => { label => 'Reject', update => 'Respond' },
            'new -> rejected' => { label => 'Quick Reject' },
            ...
            '* -> deleted' => { label => 'Delete' },
            ...
        ],
        ...
    },

Moving tickets between queues with different lifecycles

Unless there is an explicit mapping between statuses in two different lifecycles, you can not move tickets between queues with these lifecycles -- even if both use the exact same set of statuses. Such a mapping is defined as follows:

    __maps__ => {
        'from lifecycle -> to lifecycle' => {
            'status in left lifecycle' => 'status in right lifecycle',
            ...
        },
        ...
    },

SLA

%ServiceAgreements

    Set( %ServiceAgreements, (
        Default => '4h',
        QueueDefault => {
            'Incident' => '2h',
        },
        Levels => {
            '2h' => { Resolve => { RealMinutes => 60*2 } },
            '4h' => { Resolve => { RealMinutes => 60*4 } },
        },
    ));

In this example Incident is the name of the queue, and 2h is the name of the SLA which will be applied to this queue by default.

Each service level can be described using several options: Starts, Resolve, Response, KeepInLoop, OutOfHours and ServiceBusinessHours.

Starts (interval, first business minute)

By default when a ticket is created Starts date is set to first business minute after time of creation. In other words if a ticket is created during business hours then Starts will be equal to Created time, otherwise Starts will be beginning of the next business day.

However, if you provide 24/7 support then you most probably would be interested in Starts to be always equal to Created time.

Starts option can be used to adjust behaviour. Format of the option is the same as format for deadlines which described later in details. RealMinutes, BusinessMinutes options and OutOfHours modifiers can be used here like for any other deadline. For example:

    'standard' => {
        # give people 15 minutes
        Starts   => { BusinessMinutes => 15  },
    },

You can still use old option StartImmediately to set Starts date equal to Created date.

Example:

    '24/7' => {
        StartImmediately => 1,
        Response => { RealMinutes => 30 },
    },

But it's the same as:

    '24/7' => {
        Starts => { RealMinutes => 0 },
        Response => { RealMinutes => 30 },
    },

Resolve and Response (interval, no defaults)

These two options define deadlines for resolve of a ticket and reply to customer(requestors) questions accordingly.

You can define them using real time, business or both. Read more about the latter below.

The Due date field is used to store calculated deadlines.

Resolve

Defines deadline when a ticket should be resolved. This option is quite simple and straightforward when used without "Response".

Example:

    # 8 business hours
    'simple' => { Resolve => 60*8 },
    ...
    # one real week
    'hard' => { Resolve => { RealMinutes => 60*24*7 } },

Response

In many companies providing support service(s) resolve time of a ticket is less important than time of response to requestors from staff members.

You can use Response option to define such deadlines. The Due date is set when a ticket is created, unset when a worker replies, and re-set when the requestor replies again -- until the ticket is closed, when the ticket's Due date is unset.

NOTE that this behaviour changes when Resolve and Response options are combined; see "Using both Resolve and Response in the same level".

Note that by default, only the requestors on the ticket are considered "outside actors" and thus require a Response due date; all other email addresses are treated as workers of the ticket, and thus count as meeting the SLA. If you'd like to invert this logic, so that the Owner and AdminCcs are the only worker email addresses, and all others are external, see the "AssumeOutsideActor" configuration.

The owner is never treated as an outside actor; if they are also the requestor of the ticket, it will have no SLA.

If an outside actor replies multiple times, their later replies are ignored; the deadline is always calculated from the oldest correspondence from the outside actor.

Using both Resolve and Response in the same level

Resolve and Response can be combined. In such case due date is set according to the earliest of two deadlines and never is dropped to 'not set'.

If a ticket met its Resolve deadline then due date stops "flipping", is freezed and the ticket becomes overdue. Before that moment when an inside actor replies to a ticket, due date is changed to Resolve deadline instead of 'Not Set', as well this happens when a ticket is closed. So all the time due date is defined.

Example:

    'standard delivery' => {
        Response => { RealMinutes => 60*1  }, # one hour
        Resolve  => { RealMinutes => 60*24 }, # 24 real hours
    },

A client orders goods and due date of the order is set to the next one hour, you have this hour to process the order and write a reply. As soon as goods are delivered you resolve tickets and usually meet Resolve deadline, but if you don't resolve or user replies then most probably there are problems with delivery of the goods. And if after a week you keep replying to the client and always meeting one hour response deadline that doesn't mean the ticket is not over due. Due date was frozen 24 hours after creation of the order.

Using business and real time in one option

It's quite rare situation when people need it, but we've decided that business is applied first and then real time when deadline described using both types of time. For example:

    'delivery' => {
        Resolve => { BusinessMinutes => 0, RealMinutes => 60*8 },
    },
    'fast delivery' {
        StartImmediately => 1,
        Resolve => { RealMinutes => 60*8 },
    },

For delivery requests which come into the system during business hours these levels define the same deadlines, otherwise the first level set deadline to 8 real hours starting from the next business day, when tickets with the second level should be resolved in the next 8 hours after creation.

Keep in loop (interval, no defaults)

If response deadline is used then Due date is changed to repsonse deadline or to "Not Set" when staff replies to a ticket. In some cases you want to keep requestors in loop and keed them up to date every few hours. KeepInLoop option can be used to achieve this.

    'incident' => {
        Response   => { RealMinutes => 60*1  }, # one hour
        KeepInLoop => { RealMinutes => 60*2 }, # two hours
        Resolve    => { RealMinutes => 60*24 }, # 24 real hours
    },

In the above example Due is set to one hour after creation, reply of a inside actor moves Due date two hours forward, outside actors' replies move Due date to one hour and resolve deadine is 24 hours.

Modifying Agreements

OutOfHours (struct, no default)

Out of hours modifier. Adds more real or business minutes to resolve and/or reply options if event happens out of business hours, read also </"Configuring business hours"> below.

Example:

    'level x' => {
        OutOfHours => { Resolve => { RealMinutes => +60*24 } },
        Resolve    => { RealMinutes => 60*24 },
    },

If a request comes into the system during night then supporters have two hours, otherwise only one.

    'level x' => {
        OutOfHours => { Response => { BusinessMinutes => +60*2 } },
        Resolve    => { BusinessMinutes => 60 },
    },

Supporters have two additional hours in the morning to deal with bunch of requests that came into the system during the last night.

IgnoreOnStatuses (array, no default)

Allows you to ignore a deadline when ticket has certain status. Example:

    'level x' => {
        KeepInLoop => { BusinessMinutes => 60, IgnoreOnStatuses => ['stalled'] },
    },

In above example KeepInLoop deadline is ignored if ticket is stalled.

NOTE: When a ticket goes from an ignored status to a normal status, the new Due date is calculated from the last action (reply, SLA change, etc) which fits the SLA type (Response, Starts, KeepInLoop, etc). This means if a ticket in the above example flips from stalled to open without a reply, the ticket will probably be overdue. In most cases this shouldn't be a problem since moving out of stalled-like statuses is often the result of RT's auto-open on reply scrip, therefore ensuring there's a new reply to calculate Due from. The overall effect is that ignored statuses don't let the Due date drift arbitrarily, which could wreak havoc on your SLA performance. ExcludeTimeOnIgnoredStatuses option could get around the "probably be overdue" issue by excluding the time spent on ignored statuses, e.g.

    'level x' => {
        KeepInLoop => {
            BusinessMinutes => 60,
            ExcludeTimeOnIgnoredStatuses => 1,
            IgnoreOnStatuses => ['stalled'],
        },
    },

Defining service levels per queue

In the config you can set per queue defaults, using:

    Set( %ServiceAgreements, (
        Default => 'global default level of service',
        QueueDefault => {
            'queue name' => 'default value for this queue',
            ...
        },
        ...
    ));

AssumeOutsideActor

When using a Response configuration, the due date is unset when anyone who is not a requestor replies. If it is common for non-requestors to reply to tickets, and this should not satisfy the SLA, you may wish to set AssumeOutsideActor. This causes the extension to assume that the Response SLA has only been met when the owner or AdminCc reply.

    Set ( %ServiceAgreements = (
        AssumeOutsideActor => 1,
        ...
    ));

%ServiceBusinessHours

In the config you can set one or more work schedules, e.g.

    Set( %ServiceBusinessHours, (
        'Default' => {
            ... description ...
        },
        'Support' => {
            ... description ...
        },
        'Sales' => {
            ... description ...
        },
    ));

Read more about how to describe a schedule in Business::Hours.

Configuring business hours

Each level supports BusinessHours option to specify your own business hours.

    'level x' => {
        BusinessHours => 'work just in Monday',
        Resolve    => { BusinessMinutes => 60 },
    },

then %ServiceBusinessHours should have the corresponding definition:

    Set( %ServiceBusinessHours, (
        'work just in Monday' => {
            1 => { Name => 'Monday', Start => '9:00', End => '18:00' },
        },
    ));

Default Business Hours setting is in $ServiceBusinessHours{'Default'}.

Custom Date Ranges

%CustomDateRanges

This option lets you declare additional date ranges to be calculated and displayed in search results. Durations between any two core date fields, as well as date custom fields, are supported. Each custom date range is added as an additional display column in the query builder.

You can create basic date calculations via the web UI. SuperUsers can create them in the main System Configuration section. Individual users can also create date ranges in the Search options section of user preferences. More complicated configurations, such as those with custom code, can be added in your RT_SiteConfig.pm file as described below.

Business hours are also supported in calculations if you have %ServiceBusinessHours configured.

Set %CustomDateRanges to a nested structure similar to the following:

    Set(%CustomDateRanges,
        'RT::Ticket' => {
            'Resolution Time' => 'Resolved - Created',

            'Downtime' => {
                value => 'CF.Recovered - CF.{First Alert}',
                business_time => 1,
            },

            'Time To Beta' => {
                value => 'CF.Beta - now',

                format => sub {
                    my ($duration, $beta, $now, $ticket) = @_;
                    my $days = int($duration / (24*60*60));
                    if ($days < 0) {
                        $ticket->loc('[quant,_1,day,days] ago', -$days);
                    }
                    else {
                        $ticket->loc('in [quant,_1,day,days]', $days);
                    }
                },
            },
        },
    );

The first level keys are record types. Each record type's value must be a hash reference. Each pair in the second-level hash defines a new range. The key is the range's name (which is displayed to users in the UI), and its value describes the range and must be either a string or a hashref.

Values that are plain strings simply describe the calculation to be made.

Values that are hashrefs that could include:

value

A string that describes the calculation to be made.

The calculation is expected to be of the format "field - field" where each field may be:

a core field

For example, RT::Ticket supports: Created, Starts, Started, LastUpdated, Told or LastContact, Due and Resolved.
a custom field

You may use either CF.Name or CF.{Longer Name} syntax.
the word now

Custom date range calculations are defined using typical math operators with a space before and after. Subtraction (-) is currently supported.

If either field and its corresponding fallback field(see blow) are both unset, then nothing will be displayed for that record (and the format code reference will not be called). If you need additional control over how results are calculated, see docs/customizing/search_result_columns.pod.

from and to

When value is not set, from/to will be used to calculate instead. Technically, Resolved - Created" is equal to:

    { from => 'Created', to => 'Resolved' }

from_fallback and to_fallback

Fallback fields when the main fields are unset, e.g.

    {   from        => 'CF.{First Alert}',
        to          => 'CF.Recovered',
        to_fallback => 'now',
    }

When CF.Recovered is unset, "now" will be used in the calculation.

business_time

A boolean value to indicate if it's a business time or not.

When the schedule can't be deducted from corresponding object, the Default one defined in %ServiceBusinessHours will be used instead.

format

A code reference that allows customization of how the duration is displayed to users. This code reference receives four parameters: the duration (a number of seconds), the end time (an RT::Date object), the start time (another RT::Date), and the record itself (which corresponds to the first-level key; in the example config above, it would be the RT::Ticket object). The code reference should return the string to be displayed to the user.
