After thinking about this some more, the instance metrics and invocation metrics for a given EJB3 SLSB are currently exposed via two different component instances, both of type EJB3:SLSB. This goes against the rule that all components of a given type should have the same signature (i.e. set of properties and operations). At least I think this should be a rule, and I think Scott is in agreement. Otherwise, clients end up needing to first query by type and then parse the returned component names to determine the component's "sub-type", rather than being able to query on the type alone. So in this case, I think we should either have 1) a single component type EJB3:SLSB with one component instance of that type per SLSB that exposes both instance and invocation metrics or 2) two component types EJB3:SLSB-instance and EJB3:SLSB-invocation with one component instance for each of these types per SLSB Thoughts?
