Why does introspection on a Splunk 6.3.3 AIX universal forwarder not give data on Resource usage (PerProcess, Hostwide, or Dispatch)?

Hi. After having enabled introspection_generator_addon on a Universal Forwarder on AIX, I get data for partion and FishBucket, but not on Perprocess, Hostwide, or Dispatch. My Universal Forwarder is version 6.3.3, and the app has been enabled using CLI on the AIX host. After enabling, the UF has been restarted. Are there any other out there having the same problem, and have found a work around? I do not have access to the AIX machine, and have almost no knowledge about AIX. Kind Regards Lars
