Measure Free Memory/CUP using Java

[Chetan Parekh]

I want to measure Free Memory and Free CUP available on a given time using Java.

I know that there is not cross platform solution for it and I need this for Windows Platform only.

Anybody has C/C++ code or DLL that I can call from Java?

Any other solutions?

Have you tried

Runtime.freeMemory;totalMemory;maxMemory

I found following details in Java API:

Runtime.freeMemory(): Returns the amount of free memory in the Java Virtual Machine.
Runtime.maxMemory(): Returns the maximum amount of memory that the Java virtual machine will attempt to use.
Runtime.totalMemory(): Returns the total amount of memory in the Java virtual machine.

They are JVM sepcific. They are not dealing with the System Memory.

Maybe your answer.

What about using the JVMPI?

JVMPI - The Old Java Virtual Machine Performance Interface
