Can the Universal Forwarder overwite the source with transforms.conf?

[mkelderm]

(updated with correct solution)

Question: I want to overwite the source when the UF is sending data to the Splunk server. This is how it should be.

On the UF the config is splunkforwarder/etc/system/local:

inputs.conf

[monitor:///data/logs/UCMFON/*.access]
disabled = false
followTail = 1
host = $decideOnStartup
index = fon
sourcetype = access:web:ucm

On the Splunk Server (indexer) the config is splunk/system/local:

props.conf

[access:web:ucm]
NO_BINARY_CHECK=1
SHOULD_LINEMERGE=false
TIME_PREFIX=^
MAX_TIMESTAMP_LOOKAHEAD=50
TRANSFORMS-source=extract-filename-from-source

transforms.conf

[extract-filename-from-source]
# /a/b/c/e1_fgh2.log
# removes directory
#
DEST_KEY=MetaData:Source
SOURCE_KEY=MetaData:Source
REGEX  = (([\w|\d|-]*)\.\w*)
FORMAT = source::$1

One thing you're missing. Your regex is exactly "source:: ...." Drop the first part, source:: and it will work.

Thanks! Fixed the issue!

See here

If you want to use anything in transforms.conf, it has to be done on an indexer

So its valid to set the sourcetype on the UF, but the logic for setting the source will need to be moved up to your indexer(s)

Yes, both the props.conf and transforms.conf settings need to go on the indexer.

So I need to move my transforms.conf to the splunk-server (the indexer)? In the same directory?
