How can I configure REGEX to recognize/match on a multi-line event?

I have a REGEX configured (in transforms.conf) that works with my single line events, but appears to be failing on all multi-line events. Is there a special configuration necessary to get the REGEX to work on multi-line events?

Correct. The regex processor is unable to handle multi-line events without additional configuration. You'll need to tell it that the event is multi-line by using (?m) before the regular expression. For example:

REGEX = (?m)^(.*)(foobar)

LOL - duly noted. I've updated the response.

Suggested change: "The regex processor is unable to handle multi-line events" may be more accurate as: "The regex processor handles multi-line events one line at a time."
