i'd like to embed an env variable in my app label, so i add this to my app.conf:
label = My App $SPLUNK_HOME
However, the variable didn't get expanded by Splunk (i got the verbatim label)
Also tried with quotes but made no difference.
Looks like app.conf doesn't like env variables.
It looks like some of Splunk's config files do expand environment variables. Do you know if there's a list? I'm particularly interested in being able to use $HOSTNAME in transforms.conf at an intermediate forwarder to be able to track what intermediate forwarder the event passed through.
