I am running Infinispan in an embedded fashion, so it�s my code that interrogates each cache and reports the information to the monitor server. It�s actually been pretty handy because we can see the nodes that either have not started or have not formed one cluster.</span></div></div></span></blockquote><div><br></div><div>Hmm. We do expose a lot of this stuff in JMX (look at the configs [1] to switch this on). If your app is a webapp running in JBoss AS, you can use the JMX console (web based) to attach to it.
