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

## SYNOPSIS

       _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.

## 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
