=head1 NAME

rt_ticket_loadtime - Plugin to monitor the RT ticket loadtime

=head1 CONFIGURATION

The following environment variables are used by this plugin:

=over 4

=item web_url

The RT WebURL configuration parameter

=item username

The RT username

=item password

The RT password

=item ticket_id

The RT ticket id to test

=back

This configuration section shows the defaults of the plugin:

 [rt_ticket_loadtime]
     env.web_url https://localhost/
     env.username root
     env.password password
     env.ticket 1

To test the plungin run:
 munin-run --debug rt_ticket_loadtime

An appropriate test ticket should have 30 transactions or more
of type Create, Correspond or Comment and should load in about
1-10 seconds in the WebUI to have reproducible results.

If the test ticket needs more than 10 seconds to load (both WebUI
and REST values together), you have to add an appropriate timeout
value to your plugin configuration to override the munin default
timeout value of 10 seconds.
