udp://514 input exclusion

[joeybroesky]

We have logs coming in udp port 514 and want to exclude indexing events with the field "action" equaling "accept". We have tried inserting the following into the inputs.conf but does not work.

blacklist = action = "accept"

Please assist.

Hi @joeybroesky 

There seems no blacklist setting exist as per inputs conf - inputs.conf - Splunk Documentation

You can send the events to nullQueue to avoid indexing apply the following conf on HF/indexer. 

#props.conf
[your_udp_sourcetype/source::<source>/host::<hostname>]
TRANSFORMS-null= setnull
 
#transforms.conf
[setnull]
REGEX = action\s+=\s+\"accept\"
DEST_KEY = queue
FORMAT = nullQueue

An upvote would be appreciated and accept solution if it helps!
