Hi Riccardo, Yes that works for me:
Welcome to JMX terminal. Type "help" for available commands. $> open localhost:7199 #Connection to localhost:7199 is opened $>domains #following domains are available JMImplementation ch.qos.logback.classic com.sun.management java.lang java.nio java.util.logging org.apache.cassandra.db org.apache.cassandra.hints org.apache.cassandra.internal org.apache.cassandra.metrics org.apache.cassandra.net org.apache.cassandra.request org.apache.cassandra.service $> I can work with this :-) Not sure why the JVM is not listed when issuing the JVMS command, maybe its a server setting, our production servers find the Cass JVM. I've spent half the day trying to figure it out so I think I'll just put it to bed now and work on something else.
