Extracting data which is incosistent

[nateNpgh]

I need to extract a time value from log file where the time value appears with a few different variations of characters around it.  I'm struggling with handling all the variations through my regex extract.

Below are examples of each of the variations:

ChainedQuery elapsed time [90]ms

Elapsed time: 114ms

Elapsed time to get Service pool: 339

Elapsed Time: 69

,took 37ms

Is there a way to extract all the numeric values with 1 regex?

I just need to be able to handle the variations I included.

Just use an alternative within a group and you're set.

(Prefix1|prefix2|prefix3)(?<capture_field>\d+)

Hi

With those examples this should work https://regex101.com/r/jBOkh7/1

\s+[\[]?(\d+)

But this expecting that in field where you are extracting these values haven't been anything else. If those contains other text you need to modify that.

It depends how many different variants you expect to encounter and how fool-proof you want this solution to be. If you go too broadly - for example extracting every sequence of digits after a "elapsed" word (would need a separate branch for the "took" version) - you risk getting unrelated data extracted.
