Filtering input data from a udp syslog port

rhuss — Fri, 08 Oct 2010 22:52:30 GMT

I need some help filtering data from a udp (port 514) syslog input.

I know the source IP and I assume I will need a regex to exclude the records that I want to exclude, but I am confused as to what needs to be added to the config files.

Inputs.conf, props.conf and transforms.conf.

Any help you could offer this new user would be apreciated.

First, is Splunk listening on port 514, or are you having syslogd write a file for Splunk to index?

syslog-ng and some other syslog daemons can filter for you, but assuming you want Splunk to do the filtering, what you want is nullQueue.

Take a look here: http://www.splunk.com/base/Documentation/4.1.5/Admin/Routeandfilterdata#Discard_specific_events_and_keep_the_rest
