How do i get a hprof on a Citrix server?

Question

I need to capture a hprof for a Java app that is running on Citrix.

So the process is on the server but the UI is on the client machine. I can attach to the javaw.exe on the server, using VisualVM, but i am unable to capture a heap dump (gives me an error message) and the 'Profiling' tab is missing from VisualVM.

Anyone know what i need to do to get the hprof from a process which is being virtualuzed over Citrix like this?

Answer 1

I haven't used hprof, but I do do debugging and troubleshooting in Citrix environments. Things I would check/try are:

• Ensure you're setup as a local admin on the Citrix machine.
• Get the Citrix admin to publish a desktop for you and install VisualVM on the Citrix machine. Then start a desktop session using Citrix Receiver and run VisualVM and the Java app together in the same desktop session.
