Deployment Architecture

Custom EventGen samples not being indexed


So I created a simple custom app called eventgen_test, created the samples directory and added a sample.txt. Then created an eventgen.conf in /local directory. Restarted splunk and then...nothing. Ran a search within the _internal index to see what happened. Responses are as follows:

Time Event

I have adjusted the timestamp regex to match but still no luck.

Additional the eventgen.log has a bunch of these errors: I have removed SA-Eventgen so I don't know why it's trying to use it still.

Here are my eventgen.conf and sample txt

How do i get this to work?

The answer was to put the eventgen.conf into the default directory. Doesn't work in the local directory for some reason.

What I've found is if you are on Windows copy eventgen.conf to locals folder and run icacls against it to change permissions. icacls C:\program files\Splunk\etc\apps\your app here\local\eventgen.conf /grant SYSTEM:F.

Took me forever to figure this out. Also every time I edit the file I have to change perms again. Became such a pain that I wrote a c# service to watch for eventgen.conf changes and change perms automatically.
