Is there anyway to know who has created a collection in solr ? Actually if we have come collections in our solr(some users created them) and I want to know about that collections owner and some more metadata details about collections.
Is Solr configured with Ranger for security? If it is, then the Ranger audit logs for activity in Solr should be captured. Solr, without Ranger doesn't provide a real auditing capabiliity out of the box.
Is your Ranger config working at all? Or is it just the Ranger Audit UI not working? You can write to both Solr and HDFS. This will allow you to access audit data on HDFS as a backup in the event something has gone wrong with Solr.
If Ranger is configured to send audit data to Solr,you can access the Solr collection via http://solr hostname:6083/solr/ranger_audits
Here is a screenshot of the Ranger Audit config from HDP 2.5 TP Sandbox:
