This is driving me mad - have gone through the documentation and responses to queries in here but still can't get sourcetype overrided by using a transform. I'm missing something, I'm guessing obvious, but not obvious to me!
inputs.conf
[monitor:///Users/admin/Documents/splunkDataToIndex/automation_logs/]
disabled = 0
followTail = 0
index = automationlogs
props.conf
[source::/Users/admin/Documents/splunkDataToIndex/automation_logs/...]
TRANSFORMS-set_sourcetype_for_scriptlogs = set_sourcetype_for_scriptlogs
priority = 10
transforms.conf
[set_sourcetype_for_scriptlogs]
SOURCE_KEY = MetaData:Source
DEST_KEY = MetaData:Sourcetype
REGEX = .*/(.*?)\..*
FORMAT = Sourcetype::$1
Are you trying to extract the sourcetype out of the source field value?
i.e. ---> /Users/admin/Documents/splunkDataToIndex/automation_logs/
If so, your regex isnt matching anything.
