Regex : how to combine lookahead for following purpose?

I am trying to clean log files to categorize them in Splunk, so my question is:

(?i)^(?:[^ ]* ){8} ((?P.+) ((?=\d{8}\d{8}\d{10}.)|(?=\d{8}.?))

bold area needs to be combined like if/else,[it selects good before bold lines]

I want it to STOP just before just-8 digits and dot (dddddddd.) OR 8digit_8digit_10digits (8xd_8xd_10xd.)

my task is to get rid of all unique numbers on log file that i can categorize it better.

please help,

(?=\d{8}(?:_\d{8}_\d{10})?\.?) 

this satisfies my conditions above. I just need little more to add this personally.

My client needs to index MQ messages that have a variable payload from 1000 to 450k characters 😉

Does the transforms´ lookahead supports an unlimited value, like 0 or -1 ?

(?=\d{8}(?:\d{8}\d{10})?.) this satisfies my conditions above. I just need little more to add this personally.

Okay, something like this?

(?i)Message:\s*(?<message>.*?)\s*[0-9_.]{8,}

Are you possibly looking for something like this?

(?i)Message:\s*(?<message>.*?)\s*[0-9_.]*$

input of first two lines , would be those two line outputs. Like I said, I m trying to generalize log messages via Regex to have something to monitor overall at the end.

It is not clear what you're trying to do.

The fieldname will not be variable. You might be better off with sed.
Can you post some actual examples?
