Here are some examples, there are others: For a data source named xxx, the following MBean provides information on the number of connections: jboss.jca:name=xxx,service=ManagedConnectionPool For HTTP connections, you can see the thread counts in jboss.web:type=ThreadPool,name=http-99.99.99.99-8080 where 99.99.99.99 is your IP address. For servlets, you can see processing times and number of requests in jboss.web:j2eeType=Servlet,J2EEserver=none,J2EEApplication=xxx,WebModule=//hostname/xxx,name=XXX For EJBs, you can see similar information in the stats attribute for jboss.management.local:J2EEServer=local,j2eeType=bean-type,J2EEApplication=ear-file,EJBModule=jar-file,name=ejb-name View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193837#...
