We are planning to display every single running Autosys job status on Splunk dashboard, for that we would like to know exact location and logfile name that display the job status ( failed/success/suspend) for at least a week .
Release : 11.3.6
Component : WORKLOAD CONTROL CENTER
You should be looking to leverage the $AUTOUSER/out/event_demon.$AUTOSERV.* files on the scheduler host.
That shows the events the scheduler handled.
Additionally you might try posting your plan or request on the communities to see if some other customer may have already implemented things similar to what you are looking to do and is willing to share their findings.
