Monitoing of remote JVM using Jconsole

Question

I'm trying to monitor remote jvm using Jconsole. jdk1.7.0_75 is installed and configured the below parameter in jre/lib/management/management.properties file on remote machine.

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8002
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=x.x.x.x

Getting Connection failed: connection refused. checked the port number 8002 is free and disabled the firewall, Kindly provide the solution.

Answer 1

You are setting the right properties, but mixing two different approaches here. To enable JMX on your application you either need to:

• start your application with these command line parameters you used above ( java -Dcom.sun.management.jmxremote.port=8002 -cp somedependency.jar Appplication )

• add similar entries to your management.properties BUT WITHOUT the "-D" prefixes. So entries like: com.sun.management.jmxremote.port=8002
