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
