I think the answer is 'no' but thought I'd ask - does Server log any information when services are updated, e.g. Pooling setting are changed, KML capabilities are disabled, etc. Ideally would like to see is standard audit trail info - the user,'s name, a date/time stamp, and old-new values.
I'm currently running 10.4 and don't see this available anywhere in Manager or the Admin API.
I did a quick search for this in Ideas.esri.com but didn't come across anything. If you now of an idea out there, please send me the link and I'll up-vote for it a few hundred times
