sending alerts to scripts

http://wiki.splunk.com/Community:Use_Splunk_alerts_with_scripts_to_create_a_ticket_in_your_ticketing_system

To do this, set up your saved search, put it on a schedule, and set the action to trigger a shell script you've written whenever the number of events you're interested in is> 0.

Put your script (not the Remedy script) in /opt/splunk/bin/scripts.

This script should call the Java program that Remedy uses to generate tickets and pass it data from the Splunk alert. Splunk alerts support the following variables:

• $1 = number of events returned
• $2 = search terms
• $3 = fully qualified search string
• $4 = name of the saved search
• $5 = the reason the action/script was triggered (for example, the number of events returned was >1)
• $6 = a link to the saved search in Splunk +
• $7 = a list of the tags belonging to this saved search (this option was removed starting in Splunk 3.6)
• $8 = path to a file where raw results of this search are located (as opposed to passing the actual results into the ticket--this could be a lot of data).

The following example script passes the reason the script was triggered, a link to the saved search, and the path to the search results file into the ticket that the generateRemedyTicket Remedy script creates when it's run.
