Question

I am trying to monitor an application available on remote machine using VisualVM & Visual GC.

I have enabled the jmxremote on the remote side as follows:

-Dcom.sun.management.jmxremote, -Dcom.sun.management.jmxremote.port=8888,
-Dcom.sun.management.jmxremote.ssl=false, -Dcom.sun.management.jmxremote.authenticate=false

While monitoring through VisualVM, everything runs fine but VisualGC doesn’t displays any stats (getting Not Supported for this JVM error).

While tried to monitor one local application, VisualGC runs fine…

Got success with the remote app once started jstad on the remote jvm.

Is this a known issue with VisualGC…?

Remote JVM – 1.5
Local JVM – 1.6

Answer 1

Right, jstatd must be running on remote host, because VisualGC uses jvmstat and it does not use jmx.
