How can I use lookups for a source CSV file that is not under the Splunk code tree?
I am using Splunk 4.0.10. CSV lookups work fine when the file is under the Splunk code base, but it doesn't work when I place the file in a random location (accessible) separate from the code base.
You can't. You could (on filesystems that support it) link the file from a Splunk lookups directory though.
