• The host:port values are the name of the host system on which the JVM is running, and the port number specified by the system property com.sun.management.jmxremote.port when the JVM was started.

• The jmxUrl value is the address of the JMX agent to be connected to as described in JMXServiceURL.

Description

The jconsole command starts a graphical console tool that lets you monitor and manage Java applications and virtual machines on a local or remote machine.

On Windows, the jconsole command doesn't associate with a console window. It does, however, display a dialog box with error information when the jconsole command fails.
