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.
