A customer of ours is unable to see our App's Setup Action when using a Search Head Clustered environment.
They have admin permissions and are able to navigate to the Setup page via a link, so it appears that they should see it in this page.
This is expected behaviour because within a search head cluster, certain setting options are hidden on purpose.
Also apps in a search head cluster are managed using the search head cluster deployer. See the docs for more detail http://docs.splunk.com/Documentation/Splunk/latest/Admin/Deployappsandadd-ons#Search_head_clusters or http://docs.splunk.com/Documentation/Splunk/latest/DistSearch/PropagateSHCconfigurationchanges
Hope this helps ...
Makes sense -- I had a feeling that it was working as designed. Thanks!
My issue with this, is I have seen the "setup" option come and go. No rhyme or reason on why I see it sometimes, and not others.
