Confluence already has some interesting MBeans, but one that I miss a lot is an MBean that would allow us to monitor the cache.

Here is what I'd like:

Iteration 1:

make it possible to retrieve cache stats that are available via the Advanced Cache Statistics view via an MBean

Iteration 2:

make it possible to non-persistently change cache stats on the fly via an MBean

Iteration 3:

make it possible to change persistently change cache stats either via an MBean or via admin interface (CONF-12836)

(Given that optimal cache settings are critical for Confluence performance, I'm setting the priority to Major)
