Connecting to Remote JVM Processes
This section provides a tutorial example on how to use Java VisualVM to monitor JVM processes running on a remote machine with jstatd daemon or JMX agent.
From previous tutorials, we learned how to monitor JVM processes that are running on the local machine. If the JVM process you want to monitor is running on a remote machine, you need use one of the following options:
Here is an example of running LongSleep.java with the JMX agent to allow remote Java VisualVM connections.
1. Run LongSleep.java with the JMX agent turned on without requiring any connection authentication or SSL certificate:
C:\herong>\progra~1\java\jdk1.8.0\bin\java -Dcom.sun.management.jmxremote.port=6789 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false LongSleep
2. Run Java VisualVM and click "File > Add JMX Connection..." menu. You will see a dialog box displayed.
3. Enter "localhost:6789" in the "Connection" field and click OK. You will see that VisualVM connects to the LongSleep.java JVM through the JMS agent.
Once connected, you can monitor the remote JVM in the same way as a local JVM.
