Hi Paul,
A little late to the thread, but if you want to do log analysis for
how your service has been used with no performance penalties, you may be
interested in Logacity - https://www.logacity.co.uk/
It comes with a pretty and "manager-proof" interface.
(Disclaimer - I'm the developer.)
Cheers,
Jonathan

That is interesting and I have certainly seen some evidence of some of
the errors which may be what Steve is referring to. I’m not sure I’d
go as far as ‘break’ but certainly it may be introducing some bugs.
With regard to speed, we clean out the tables daily using procedures
in our database. These run a series of summary statistics which we
then keep so we avoid any potential cost in that regard but we do get
a wealth of very useful historical usage information when it is running.
We have also been developing methods which use the Tomcat access logs
and FME / Power BI so I guess we will just have to switch to those if
the plugin is not supported.

Hi Andrea,
We use Monitor Hibernate and lately we upgraded to Geoserver 2.13
and the extension definitely breaks Geoserver from infact version
2.12 for us.
Sad to hear... but one more reason to drop the module out of supported
status, since nobody would look into it.
On performance, we have't performed any tests and we have't
cleaned the database since we started using it for monitoring
close to 10 Geoserver instances.
I would imagine it adds costs in request time as it has to write
to the database every request data.
The database write gets slower and slower over time as the cost for
checking primary key uniqueness increases. Once you hit the millions
of entries,
in our tests, that time becomes comparable (or bigger, for GWC
requests) than the request processing itself, making
monitoring-hibernate a liability.
Cheers
Andrea
