Splunk Search

The Join command doesn't combine results from different indexes

The search string shown below returns valid results when run in Splunk 4.3.4 but it doesn't in Splunk 5.0.

index=agent MTRn |fields MTRn S| join S [search svc="*"| fields svc, sessionId Site | rename sessionId AS S]|table MTRn S Site

The result shows empty values for the "MTRn" column and the "S" and "site" columns show data from the subsearch.

Cheers,

The sub-search searches data in the "main" index whereas the outer does it in the "agent" index. I tried to include the index=main clause to no avail.

Your inner search is an entirely separate and unrelated search from the outer search, so it needs to also include the index to search: ie:

index=agent MTRn |fields MTRn S| join S [search index=agent svc="*"| fields svc, sessionId Site | rename sessionId AS S]|table MTRn S Site
