Splunk Search

Using transforms.conf to create a new field

I have events which include:

.... relevant=False ....

and I'd like to transform those at search time into a field that doesn't yet exist:

.... compliant=True ....

I thought that this transforms entry, along with the associated props REPORT would do it, but I'm missing something:

# Flip the relevant result to a compliant field
[rtc_comp]
SOURCE_KEY = relevant
DEST_KEY = compliant
REGEX = False
FORMAT = True

Thanks in advance!

The problem here is probably that regex-based field extractions take place before automatic field=value extractions. Your best bet here isn't to use field extractions to map relevant to compliant, but rather to use a csv lookup table to create the new field. It will be higher performance especially if you want to refer to "compliant" in the search itself.

Thank you, sir! That was my next destination. Incidentally, is there data regarding the performance of various actions, or some sort of performance priority chart?
