Hi Guys, In Splunk a field by name “event_sub_type” has multiple values. We don’t want to ingest any logs into splunk whose field “event_sub_type” value is either “WAN Firewall” or “TLS” (as marked in attached screen shot) as these are huge unwanted logs. Our search query is : index=cato sourcetype=cato_source We tried multiple ways by editing the props.conf and transforms.conf to exclude these logs as below but none of them are successful to exclude those logs; props.conf [sourcetype::cato_source] TRANSFORMS-filter_logs = cloudparsing transforms.conf [cloudparsing] REGEX = \"event_sub_type\":\"(WAN Firewall|TLS)\" DEST_KEY = queue FORMAT = nullQueue Can someone please guide how to exclude these events whose “event_sub_type” value contains either “WAN Firewall” or “TLS” by editing props.conf and transforms.conf?
