Remote JMX connection

Question

I\'m trying to open a JMX connection to java application running on a remote machine.

The application JVM is configured with the following options:

• com

Answer 1

In my testing with Tomcat and Java 8, the JVM was opening an ephemeral port in addition to the one specified for JMX. The following code fixed me up; give it a try if you are having issues where your JMX client (e.g. VisualVM is not connecting.

-Dcom.sun.management.jmxremote.port=8989
-Dcom.sun.management.jmxremote.rmi.port=8989
