Monitoring Engines Using JMX

JMX can also be used to monitor Engines’ JVMs. You can enable this in an Engine Configuration, in the Engine JVM section, by setting a command-line argument to start the JMX server.

A parametrized incremental port is available for passing into Engine JVM arguments. For example, setting the command-line argument
-Dcom.sun.management.jmxremote.port=${startport:9977} sets the JMX port to 9977 plus the Engine instance number.
