NAME
       jconsole - Starts a graphical console that lets you monitor and manage Java applications.

SYNOPSIS
       jconsole [ options ] [ connection ... ]


       options
              The command-line options. See Options.

       connection = pid | host:port | jmxURL
              The pid value is the process ID of a local Java Virtual Machine (JVM). The JVM must be
              running with the same user ID as the user ID running the jconsole command.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.

              For more information about the connection parameter, see Monitoring and Management

              See also the JMXServiceURL class description at

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 does not associate with a console window. It does, however,
       display a dialog box with error information when the jconsole command fails.

OPTIONS
       -interval=n
              Sets the update interval to n seconds (default is 4 seconds).

       -notile
              Does not tile windows initially (for two or more connections).

       -pluginpath plugins
              Specifies a list of directories or JAR files to be searched for JConsole plug-ins. The
              plugins path should contain a provider-configuration file named META-
              INF/services/com.sun.tools.jconsole.JConsolePlugin that contains one line for each
              plug-in. The line specifies the fully qualified class name of the class implementing
              the com.sun.tools.jconsole.JConsolePlugin class.

       -version
              Displays release information and exits.

       -help
              Displays a help message.

       -Jflag
              Passes flag to the JVM on which the jconsole command is run.
