I have a tomcat instance with the JMXRemote parameter configured. The local VisualVM is able to get a sampler on CPU, however, not for Memory. The memory button is grayed out wi

Answer 1

I've got the same problem but with different envirnoment. My server was a Linux machine, the client a Windows 7 machine, but the problem is the same.

The solution was to launch the jvisualvm in the same machine and with the same user that is running the targeted application. If i run jvisualvm with other other user (ex: root) the memory button became gray.
