issues with splunk app for active directory

freeborn
Explorer

I cant seem to run any reports within the splunk app for active directory.

For instance if I run user logon failures i get "Lookup table 'HostInfo' is empty."

Administrator audit: I get Lookup table 'HostInfo' is empty. and Lookup table 'tSessions' is empty.

Any help is appreciated since I am trying to set this up to present prior to purchasing.

Please open up a new issue / answers - your situation may be different. Don't forget to include what version of the app you are running, what version of windows, what version of splunk, etc.

Adrian, was there a solution to this problem? I am also having the same issue. I did verify also that my auditing matches the documentation.

The tHostInfo and tSessions tables are generated by saved searches that run on a five minute schedule. There are a couple of reasons why they would not be shown:

  1. You have not turned on Audit on all your domains as described in the setup documentation
  2. You are running Admin Audit with a search period that is less than five minutes
  3. You have a more complex environment and your saved searches are not generating the files in the right place (unlikely if you are using the free version - this is more common in complex multi-search-head environments)
  4. For some reason, the saved search is not firing (also uncommon)

I suspect #1 is the culprit. If you don't enable audit, then successful logons don't get recorded, and the tSessions and tHostInfo look ups will be empty as a result of no events.

Get in touch with your Splunk sales team and ask them to get me involved. We'll get something sorted.

I've just had another report of the tHostInfo table being broken, and I am investigating. It doesn't happen on my system, so any information you can provide on your AD environment would be appreciated.
