I think it is a good idea to get an overview of all cache entries that
are never used at all.

Also a general request counter would be useful (number of request in the
last 5 minutes, 60 minutes, 24 hours, since system start).

Finally a list of all available properties (see the settings bean) would
be a good idea.
