I need help with a REGEX that needs to extract just fourth field in a line and nothing else.
The event looks like this:
Switch : 800471-00-04 1215G-04161 xxxxx xxxxx xxxx ........

Al I need is the "1215G-04161" portion of that line Can someone give me a quick regex for that?

Thanks!

if you want the field for all events which start with the word Switch

EXTRACT-field4= (?i)Switch\s+:\s+\S+\s+(?P<4field>\S+-\S+)

Assuming each field is a block of non-spaces, and assuming each field is separated by spaces, you can do this:

^(\S+\s+){3}(?<field4>\S+)
