Hi Scott,
You can download a Splunk application from splunkbase.
http://www.splunkbase.com/apps/All/Availability/app:Splunk+for+Change+Management#
If you install the application in /opt/splunk/etc/bundles/change_management it will include two scripts, rlog.sh and readlog.py. Readlog.py reads a log file and manages previous reads and logrotate. rlog.sh pipes the log output through ausearch and into Splunk. The rest of the files set up inputs, example saved searches and a dashboard.
This application is preliminary and will be improved and updated over the next few months. If you have trouble with it, post here and I'll assist. You can also join the support maillist at Splunk, support@xxxxxxxxxx, which will also get to me.
Cheers,
Harper
