Run A Java Process to Listen to JVisualVM Requests from Other Hosts

Let's say you have a Java program, testjmx.TestIt, on your machine that has IP address 192.168.1.148. Run it like so:

mwood@workstation:~/workspace/testjmx/bin$ java \
    -Dcom.sun.management.jmxremote.port=1234 \
    -Dcom.sun.management.jmxremote.authenticate=false \
    -Dcom.sun.management.jmxremote.ssl=false \
    -Djava.rmi.server.hostname=192.168.1.148 \
    testjmx.TestIt

The first three defines are well-documented; the last define, where you spell out to RMI what host it's runing on, is not very well documented, but there's a note about it here:

The hostname that you define in the java.rmi.server.hostname system property must match exactly the hostname you use when connecting from JVisualVM.

Then, on another machine, just do this:

mwood@laptop:~$ jvisualvm

Add a new JMX connection to localhost:1234, then find that new connection in the left-hand pane, and double-click on it to start monitoring.
