Split syslog input into multiple indexes

I'm trying to split messages that come into splunk via UDP:514 (single input, single sourcetype) into multiple indexes based on a regex that should be applied to the _raw message.

I've tried several suggestions i've found in splunk-base but nothing seems to work 😞

My current configuration looks like this:

inputs.conf

[tcp://8514]
connection_host = ip
sourcetype = syslog

props.conf

[syslog]
TRANSFORMS-index=route-to-index

transforms.conf

[route-to-index]
REGEX = ^<\d+>(app|pubsub|updater)(?:\[(\d+)\])?:\s
FORMAT = index::myindex
WRITE_META = true

The inputs.conf is in etc/system/local/inputs.conf, props and transforms are in a custom app.

The goal is to filter based on the process name for now. The regex definitely matches the messages, but nothing appears in myindex.

You're pretty close. In your

transforms.conf

[route-to-index]
REGEX = ^<\d+>(app|pubsub|updater)(?:\[(\d+)\])?:\s
FORMAT = myindex
DEST_KEY = _MetaData:Index

Should do the trick.

Is this sill working if in inputs.conf an index is defined?
Let's say:

index = main
