F5 BIG-IP linebreaking

m_zandinia — Sat, 18 Sep 2021 18:25:29 GMT

Hi Splunkers!

I have a problem with line breaking in Splunk add-on F5-bigip. I've tried some regex to break the line correctly but I'm not successful.

First of all for simplicity I changed my outputs.conf in Heavy Forwarder.

outputs.conf

[indexAndForward] index = true

In fact the indexing is false on this node and this HF forward data to my indexer cluster and I also have search head cluster. But as I mentioned just for simplicity I turned mu indexing to true in this HF.

Then I used these regexes to break the lines

props.conf

[f5:bigip:syslog] # LINE_BREAKER = ^()\w{3}\s\d{2}\s\d{2}:\d{2}:\d{2} # LINE_BREAKER = ^\w{3}\s\d*\s\d{2}\W\d{2}\W\d{2} LINE_BREAKER = ([\r\n]+)\w{3}\s\d+\s\d{2}\W\d{2}\W\d{2} # LINE_BREAKER = ([\r\n]+) # LINE_BREAKER = \n MAX_TIMESTAMP_LOOKAHEAD = 16 # ADD_EXTRA_TIME_FIELDS = subseconds NO_BINARY_CHECK = true # EVENT_BREAKER_ENABLE = false # TIME_FORMAT = %b %d %H:%M:%S TIME_PREFIX = SHOULD_LINEMERGE = false TRUNCATE = 1000000

This is some of my data that I can't break the line correctly.

First, make sure the inputs.conf file specifies the right sourcetype. Also, be sure to restart Splunk after changing a config file.

Try these props.conf settings:

[f5:bigip:syslog] LINE_BREAKER = ([\r\n]+)\w{3}\s+\d+\s\d{2}:\d{2}:\d{2} MAX_TIMESTAMP_LOOAKAHEAD = 16 TIME_FORMAT = %b %d %H:%M:%S TIME_PREFIX = ^ SHOULD_LINEMERGE = false TRUNCATE = 1000000

Thanks for your time. It's worked perfectly. Just I have a misspelling in my post. I've corrected it so you do.

MAX_TIMESTAMP_LOOAKAHEAD = 16

MAX_TIMESTAMP_LOOKAHEAD = 16
