Configuring Nullqueue on Splunk for Windows

I'm needing to filter certain syslog events before indexing to stay below our license limit. These syslog events are from a Cisco ASA and I know the source subnet to be filtered. Routing to the nullqueue sounds like the option I need to use but I just don't see how to do it on Splunk for Windows.

Sorry for the newby question but can anyone assist?

Thanks!!!!

Can you try placing the transforms.conf and props.conf in the app directory is where sourcetype=cisco_asa is configured.

I am guessing this will be $SPLUNK_HOME/etc/apps/Splunk_CiscoFirewalls/local

All should be well

Steelwool, did you find a solution for your issue?

I followed the guide mentioned by ziegfried and created the files:

C:\Program Files\Splunk\etc\system\local\props.conf

[cisco_asa]
TRANSFORMS-null= setnull

I also tried :

[source::udp:2000]
TRANSFORMS-null= setnull

I use the Cisco Security Suite App, thus the syslog port moved to 2000 for coexistence with the standard syslog service.

C:\Program Files\Splunk\etc\system\local\ransforms.conf

[setnull]
REGEX = (ASA-6-302014|ASA-6-302013|ASA-6-302016|ASA-6-302015)
DEST_KEY = queue
FORMAT = nullQueue

I have no idea what I should try next 😕 Please help!

You just have to create those files (props.conf and transforms.conf) in $SPLUNK_HOME/etc/system/local. Follow this guide: http://www.splunk.com/base/Documentation/4.1.6/Admin/Routeandfilterdata

Sorry, meant to add that I expected to find the profs and transforms config files in the HOME/etc/system/local directory to edit them but they were not there.
