Read the same metric, but from the domain-level resource:

[{"profile" => "production"},{"subsystem" => "datasources"}, 
{"datasource" =>  "XXX"}]

The result would incorporate the values for all servers that are running 
the "production" profile. See "Multi-Server Responses" on 
http://community.jboss.org/docs/DOC-16354.

Limiting the result to servers in a particular server group could be 
done with a parameter to the operation.
