[jboss-as7-dev] Exposing runtime state

How can I retrieve runtime state from the domain model? For instance: - the number of server instances running on a host? - the number of connections in use (JCA Pool) on a host? - the number of connections in use across servers? A pseudo code expression for the operation and it's return values would be helpful. I am especially interested in addressing of those operations and the distinction between runtime state for the domain (i.e. number of server instances) and runtime state of a particular host. Ike
