Heavy Forwarder, Syslog filter

benedetto
Engager

Hi all,

How can I create a filter that sends just Syslog login and logout events? I have a Syslog on different machines that send syslog events to each their own forwarders and then come to indexer. How can I create a filter that has as sourcetype syslog?

thanks in advance,
Best regards.

here is your answer : Keep specific events and discard the rest

http://docs.splunk.com/Documentation/Splunk/4.3.4/Deploy/Routeandfilterdatad#Keep_specific_events_an...

Here is an example, please time the regex to your events.
In props.conf, set the TRANSFORMS rule for any syslog soucretype

[syslog]
TRANSFORMS-filtersyslog= setnull,keeponlyloginlogout

Create a corresponding stanza in transforms.conf.
`
[setnull]
REGEX = .
DEST_KEY = queue
FORMAT = nullQueue

[keeponlyloginlogout]
REGEX = (login|logout)
DEST_KEY = queue
FORMAT = indexQueue
`
