Line breaker for multiline communigate logs

robgreen — Tue, 10 Apr 2012 02:10:12 GMT

Hello,
I have onbox Communigate logs i am trying to get imported into splunk for the PBXApp application. It logs multiline data where the "sender" is unique until it changes. for example

00:00:00.423 5 SIP [a.b.c.d]:5060 <- [a.b.c.d]:5060 inp(527): BYE sip:signode-35888-1B5CE480@a.b.c.d SIP/2.0\r\nVia: SIP/2.0/UDP a.b.c.d.

would be

time loglevel sender message

Maybe i am over thinking this or maybe splunk can't do this, but i want all logs with "sender" being the same until it changes to be one event. I have the data below (and extra line breaks to show where i want the event data split).

00:00:00.423 5 SIP [a.b.c.d]:5060 <- [a.b.c.d]:5060 inp(527): BYE sip:signode-35888-1B5CE480@a.b.c.d SIP/2.0\r\nVia: SIP/2.0/UDP a.b.c.d

Once the "sender" changes then there is no going back.. Said another way, the log lines are not interspersed.

Is this possible? A side question but of lesser importance is that the "date" of the log line is in the filename, is there a way to extract it from it? i.e. the above contents would be a in a file called 2012-04-09.log.

thanks,
rob

No you can not do this at index time. You would have to index each line separately, and then you could use the transaction command at search time to assemble the events, something like | transaction sender maxspan=2

Try adding this to your props.conf:

SHOULD_LINEMERGE = 1 BREAK_ONLY_BEFORE = /d+/:/d+/:/d+/./d+/s/d/sSIP/s+/[/w/./w/./w/./w/]/:/d+

The regular expression matches:

00:00:00.423 5 SIP [a.b.c.d]:5060

/d+ means 1 or more digits, /: means the character ":" is literal, /w+ means 1 or more alphabetical characters and finally, I have used a.b.c.d literally as four alphabetical chars with periods between them, if it needs to be changed to an IP address, replace "/w+" by "/d+".

This config will allow each SIP call as 1 event with multiple lines.

NOTE: Setting SHOULD_LINEMERGE = 1 does come with a slightly greater load on Splunk, so please test the load before applying to PROD.
