I'm a newby to both splunk and itsi. I think I can figure out how to find the fields in a lookup table and in an index, however, despite the name of this thing (itsi_event_management_group_index), it seems not to be an index as preceding it with "index=" yields no results, thus I can't figure out how to determine the names of the fields contained within it. I've been provided with a query which references some of the fields via the 'stats' command, but... 1) How do I identify all such fields, and 2) what is this thing if not an index or lookup table?
