## 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
              Using JMX Technology at
              <http://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html>

              See also the **JMXServiceURL** class description at
              <http://docs.oracle.com/javase/8/docs/api/javax/management/remote/JMXServiceURL.html>

## 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.

### -J_flag_
              Passes **flag** to the JVM on which the **jconsole** command is run.
