How to exclude lines from a log --IndexQueue

IreneAsdfgk

We are trying to index only events that contain a certain structure set by a regular expression: \ S + \ s \ S + \ s \ ((\ S + | \ w + | ./ \ w +) ) : \ s (DATE | END | Running).
However, when we assign the indexQueue property in transforms.conf, it doesn't work:

[takedata]
REGEX = \ S + \ s \ S + \ s \ ((\ S + | \ w + | ./ \ w +) \) \: \ s (DATE | END | Running)
DEST_KEY = queue
FORMAT = indexQueue

If we do it with the nullQueue, we exclude the rows that correspond to that expression.

[excludedata]
REGEX = \ S + \ s \ S + \ s \ ((\ S + | \ w + | ./ \ w +) \) \: \ s (DATE | END | Running)
DEST_KEY = queue
FORMAT = nullQueue

Can any help us?

Thanks.

You need to do both and in the specific order as explained in the link below. What this does is "send everything to the nullQueue, except the events that match this regex". Like this:

[your_sourcetype]
TRANSFORMS-set= excludedata,takedata

[excludedata]
REGEX = .
DEST_KEY = queue
FORMAT = nullQueue

[takedata]
REGEX = \ S + \ s \ S + \ s \ ((\ S + | \ w + | ./ \ w +) ) : \ s (DATE | END | Running)
DEST_KEY = queue
FORMAT = indexQueue

Can you let me know if you tweaked outputs.conf too ?
I am facing same issue - I can't filter in events to include events but exclude filter works. My config is running on standalone SH .
I added in outputs.conf too - how can I make it work ?

[tcpout:setparsing]
server=localhost:8000

Props.conf
[OktaIM2:log]
TRANSFORMS-set= setnull,setparsing

transforms.conf
[setnull]
REGEX=gmail.com
DEST_KEY=queue
FORMAT=nullQueue
[setparsing]
REGEX=yahoo.com
DEST_KEY=queue
FORMAT=indexQueue
