NAME

       RT::Extension::Nagios - Merge and resolve Nagios tickets

DESCRIPTION

       Nagios <http://www.nagios.org> is a powerful monitoring system that enables organizations
       to identify and resolve IT infrastructure problems before they affect critical business
       processes.

       This extension allows email alerts generated by Nagios to be aggregated and resolved as it
       generates them.  It does this by examining the standard subject line that Nagios
       generates; by default, these take the form:

           PROBLEM Service Alert: localhost/Root Partition is WARNING

       There are 5 useful parts in subject; we call them "type", "category", "host",
       "problem_type" and "problem_severity".  These are parsed from the subject via a regular
       expression; in the above example, the extension would extract:

           type:             PROBLEM
           category:         Service
           host:             localhost
           problem_type:     Root Partition
           problem_severity: WARNING

       After the new ticket is created, the following is done:

       1.  Find all the other active tickets in the same queue with the same values of
           "category", "host" and "problem_type".  If the configuration setting
           "NagiosSearchAllQueues" is set (see below), all queues are searched.

       2.  If the configuration setting "NagiosMergeTickets" is set (see below), merge all
           matching tickets.

       3.  If "type" is 'RECOVERY', resolve them.

INSTALLATION

       "perl Makefile.PL"
       "make"
       "make install"
           May need root permissions

       "make initdb"
           Only run this the first time you install this module.

           If you run this twice, you may end up with duplicate data in your database.

           If you are upgrading this module, check for upgrading instructions in case changes
           need to be made to your database.

       Edit your /opt/rt4/etc/RT_SiteConfig.pm
           If you are using RT 4.2 or greater, add this line:

               Plugin('RT::Extension::Nagios');

           For RT 4.0, add this line:

               Set(@Plugins, qw(RT::Extension::Nagios));

           or add "RT::Extension::Nagios" to your existing @Plugins line.

       Restart your webserver

CONFIGURATION

       This extension has three configuration settings; setting them should be done in
       "RT_SiteConfig.pm".

       "NagiosSearchAllQueues"
           If set, this causes step 1, above, to search for matching Nagios tickets in an queue.
           In most configurations, Nagios notifications will arrive in one queue, and remain
           there.  If your workflow involves triaging Nagios notifications from there into other
           queues, you will want to set:

              Set( $NagiosSearchAllQueues, 1 );

       "NagiosMergeTickets"
           Controls if the extensions merges tickets about the same incident together.  By
           default, each "PROBLEM", "ACKNOWLEDGEMENT", "FLAPPINGSTART", "FLAPPINGSTOP" and
           "RECOVERY" notification will remain as its own ticket; when the "RECOVERY" email is
           received by RT, all will be resolved.

           Setting this configuration parameter to 1 causes the extension to merge all old
           tickets on the same topic into new tickets as they arrive; as such, the "Created" date
           will respect the most recent message.

           Setting it to "-1" causes the extension to merge new tickets into any existing tickets
           as they arrive; the "Created" date will respect the oldest message, and the ticket ID
           will remain constant:

               Set( $NagiosMergeTickets, -1 );

       "NagiosResolvedStatus"
           Since RT allows for custom lifecycles on queues, this extension's default of setting
           tickets to "Resolved" upon "RECOVERY" may be incorrect for the queue they are in.  If
           the queue your Nagios tickets reside in does not have a "Resolved" status, or you
           would like tickets to be transitioned to a different status on "RECOVERY", set
           "NagiosResolvedStatus":

               Set( $NagiosResolvedStatus, 'recovered' );
