Receiving timestamp parsing error

[vjsplunk]

I am trying to set timestamp for the event :

========

Sat Mar 19 16:33:08 2022 -05:00

LENGTH : '228'

ACTION :[7] 'CONNECT'

DATABASE USER:[1] '/'

=========

The rules I used are:

TIME_FORMAT = %a %b %d %H:%M:%S %Y %:z

TIME_PREFIX = ^

MAX_TIMESTAMP_LOOKAHEAD = 32

It is catching the timestamp correctly. However showing the error "could not use strptime to parse timestamp from LENGTH : '228' "

I am not sure how to resolve the error.

Thank you. These are the sample lines:

Have you set the following attributes properly? It seems an issue with the line-breaking or line-merging because Splunk is also trying to parse the timestamp on the second line as well.

• SHOULD_LINEMERGE
• LINE_BREAKER

[vjsplunk]

Yes. I have applied the below 2 rules:

LINE_BREAKER = ([\r\n]+)

SHOULD_LINEMERGE = true

Line breaking is proper. Not sure it is showing the error

[VatsalJagani]

If SHOULD_LINEMERGE=true then you have specified when to break the event.

I would suggest using SHOULD_LINEMERGE=false and updating the LINE_BREAKER accordingly. (Gives better performance and hopefully resolves your error too.)

Please provide two-three sample events as they are in the file and I can help you write the LINE_BREAKER.

[VatsalJagani]

It seems you have a single line event, use SHOULD_LINEMERGE=false then along with your current configuration.
