The local VisualVM is able to get a sampler on CPU, however, not for Memory.The memory button is grayed out with a summary saying: Memory sampling: Not available.Make sure the application is running on a supported JDK 6 or JDK 7.
Java: 1.6.030; Java HotSpot(TM) 64-Bit Server VM (20.5-b03, mixed mode). You must have downloaded the version from jvisualvm homepage, right. If you use new jdk 1.7, VisualVM is already packaged in your jdk folder. Use this version, you will not have any problem with memory sample. ![]() If i run jvisualvm with other other user (ex: root) the memory button became gray. Just in case anyone else is still having trouble and ends up this far down the thread, I was using the JDK that is part of the weblogic server configured through Eclipse and not the JDK that I installed seperately. Im still a junior programmer and I wasnt putting 2 and 2 together until I started looking through my eclipse settings and verified my Installed JREs.
