Field extraction using Field Extractor

gcusello — Mon, 17 Oct 2016 10:47:31 GMT

Hi at all,
I would extract a field as a part of source field and I know how to do this using rex command

| rex field=source "myregex"

but I'd like to configure this field once and not in all my searches.
I tried putting in field extractor

field=source "myregex"

but there's something wrong!

Anyone has any idea?

Bye.
Giuseppe

The field extractor looks in the entire event. It's equivalent to rex field=_raw "myregex". You'll have to adjust your 'myregex' string to extract the desired field from the whole event.

Hi,

try this. You cannot use the "Field Extractor" for this. Need to Settings --> Fields --> Field extractions --> New

"myregex" in source

looks something like this then.

(?<newfield>.*) in source

Thank you.
