Subject Re: solr audit logging
Date Tue, 06 Dec 2016 19:34:09 GMT
Thanks very much the trace idea is a brilliant way to dig into it. Did not
occur to me.

I had another coworker suggest the custom

this is beyond my litmited abilites.

I will see what we can dig up out of the logs...

the original request was this...

"Is there any configuration, plugin, or application that will create an
audit trail for Solr requests? We have teams that would like to be able to
pull back changes/requests to documents in solr given a time period. The
information they would like to retrieve is the request to solr, where it
came from, and what the request did."

I am starting to think there is not a simple solution to this. I was hoping
there was an UpdateAudit class or something I could flip a switch on or
some such...
