This property specifies the port on which the vRealize Hyperic server the Java virtual machine listens for JMX requests, if JMX is enabled.

By default, JMX is disabled. The property that controls whether or not JMX is enabled is server.jms.usejmx.

The primary reason to enable JMX is to enable monitoring of the vRealize Hyperic server's internal ActiveMQ server. With the port closed, a vRealize Hyperic agent on the same platform as the vRealize Hyperic server will discover ActiveMQ, but cannot obtain ActiveMQ metrics.
