获取线程的内存使用情况

Question

I know that I Java's Runtime object can report the JVM's memory usage. However, I need the memory usage for a certain thread. Any idea how to get this?

I appreciate your answer!

Answer 1

A Thread shares everything except its stack and the CPU cycles with all other threads in the VM. All objects created by the Thread are pooled with all the other objects.

The problem is to define what the memory usage of a Thread is. Is it only those objects it created? What if these objects subsequently are referenced by other threads? Do they only count half, then? What about objects created somewhere else, but are now referenced by this Thread?

I know of no tool trying to measure the memory consumption of separate Threads.
