## OPTIONS

- \-interval

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

- \-notile

  Doesn't tile the windows for two or more connections.

- \-pluginpath *path*

  Specifies the path that jconsole uses to look up plug-ins. The plug-in *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.

  Prints the program version.

- *connection* = *pid* \| *host*:*port* \| *jmxURL*

  A connection is described by either *pid*, *host*:*port* or *jmxURL*.

  - •

    The *pid* value is the process ID of a target process. 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.

- \-J*input\_arguments*

  Passes *input\_arguments* to the JVM on which the jconsole command is run.

- \-help or --help

  Displays the help message for the command.

## 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.
