[infinispan-dev] Metrics and interceptors

[Tristan Tarrant]

A recent issue with some refactoring of the PassivationInterceptor 
affecting code using it directly (EAP's Infinispan subsystem), has got 
me thinking about the fact that we have somewhat treated interceptors as 
a form of API since we do not provide another way of retrieving metrics 
collected by the interceptors, aside from the basic cache stats.
With the plan to eventually drop interceptors, these kind of metrics 
should be exposed through a more stable API (aside from maintaining 
stability of the MBean side of things).

The org.infinispan.stats.Stats interface already partially covers that 
for basic stats (see org.infinispan.cache.AdvancedCache.getStats()), and 
I think it should be extended or at least complemented to do this.

WDYT ?
