How to configure the inputs.conf to only allow specific event IDs and only filter on a wildcard username?

Hi fellas,

Testing the product out.
Have 2012 DC --> UF --> Splunk test environment

I've figured out how to configure the inputs.conf to only allow specific event IDs through the whitelist
Is it possible to also only filter on a wildcard username? Let's say I have an environment where every admin starts with SUPER_ADMIN_X

Been trying to figure it out with no luck.

This is what I've been working with:

[WinEventLog://Security]
disabled = 0
# only index events with these event IDs.
whitelist = 4624,4634 
Message = Account\sName:\s+*super*

I think you are looking for this :

let me know if this helps!

Thanks - been down this road - but to no avali.

Would you happen to have an example of multi-line filtering?
Such as

All Events for 1234, 4321
and
All those events for a wildcard username "admin_*" for example?

I haven't had much luck with my googlefu.

Did this with props.conf and transforms.conf

Props.conf

[source::*:Security]
TRANSFORMS-set = setnull,seclog

transforms.conf

[seclog]
REGEX = (?msi)(^EventCode=4634|4632).*(Account\sName:\t\tSUPER.)
DEST_KEY = queue
FORMAT = indexQueue

This is all for testing and obviously needs fine tuning for more appropriate eventID's and message information. Will attempt with different logon types, etc

(?msi)(^EventCode=4634|4624).*(Logon\sType:\t\t[1-3]).*(Account\sName:\t\tSUPER.)

Hope this helps someone in the future.
Cheers!
