Transforms: why is nullQueue not working?

[amiftah]

Hello,

I want to discard events that contain a string "Content", the following doesnt work, because I still see events with Content after I restarted and re-indexed:

transforms.conf
[allNullQueue]
REGEX = Content
DEST_KEY = queue
FORMAT = nullQueue

props.conf
[mysrctype]
TRANSFORMS-setnull = allNullQueue

I tried this in a standalone env, version 7.0.3 and 7.1.2
I can't find out where the problem is coming from.

Any clue?
Thanks

I was missing a Lookahead, because my Content is positioned beyond the 4096 characters which is the default value for lookahead.
Thank you for your answers!

1. must be Splunk Enterprise (not Universal Forwarder)
2. props.conf should reference source not sourcetype

3. props.conf TRANSFORMS class and stanza name should be unique across deployment, not just specific config file

   props.conf
   [source::/mysource/example/*.csv]
   TRANSFORMS-setnull = allNullQueue

   transforms.conf
   [allNullQueue]
   REGEX = Content
   DEST_KEY = queue
   FORMAT = nullQueue

[marycordova]

this is Splunk Enterprise and not a universal forwarder correct?

Hi, do you have the same TRANSFORMS-setnull class defined elsewhere apart from the props.conf in question? You can check this by running a btool on your props splunk btool props list --debug | grep 'TRANSFORMS'.
