jconsole usage

Usage: jconsole [ -interval=n ] [ -notile ] [ -pluginpath <path> ] [ -version ] [ connection ... ]

  -interval   Set the update interval to n seconds (default is 4 seconds)
  -notile     Do not tile windows initially (for two or more connections)
  -pluginpath Specify the path that jconsole uses to look up the plugins
  -version    Print program version

  connection = pid || host:port || JMX URL (service:jmx:<protocol>://...)
  pid         The process id of a target process
  host        A remote host name or IP address
  port        The port number for the remote connection

  -J          Specify the input arguments to the Java virtual machine
              on which jconsole is running

Command line

[dave@dave app]$ jconsole -J-Djava.class.path=$JAVA_HOME/lib/jconsole.jar:$JAVA_HOME/lib/tools.jar:$WL_HOME/server/lib/wlfulclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote -debug
