[jboss-as7-dev] Exposing runtime state

[Heiko Braun]

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.
