JConsole: A tool from Sun to let you monitor Java programs while they are running. It will tell information about performance and resource management. It is designed to work remotely attaching to the app via an MBean (Managed Beans) server. There is nothing to download. Everything you need comes bundled in the JDK. You invoke it to monitor a locally-running Java app like this:
rem demonstrate JConsole
rem load the sample progrom to monitor: Java2Demo, enabling monitoring with com.sun.management.jmxremote property
rem The following should be all on one line:
"J:\Program Files\java\jdk1.6.0_06\bin\java.exe" -Dcom.sun.management.jmxremote -jar "J:\Program Files\java\jdk1.6.0_06\demo\jfc\Java2D\Java2Demo.jar"
rem in a separate BAT file do the following so you can have both programs running at once.
rem load JConsole to watch Java2Demo
"J:\Program Files\java\jdk1.6.0_06\bin\jconsole.exe"
If that does not work, add these system properties to the command line as well:
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.port=9999
Pick an unused socket to use for communication.
