Sorry, only just saw which version you're referring to. JMX attribs were only exposed in JBoss Cache from version 1.3.0.GA. The version embedded in JBoss App Server 3.2.6 is pre-1.0. So even though your version of JGroups exposes JMX info, JBoss Cache doesn't bind this to JMX until 1.3.0.GA. A few questions: 1) Does your JBoss AS installation run in a cluster? 2) Is upgrading your version of JBoss AS feasible?
