Statistics of objects in old generation?

Question

Is there any tool to view object statistics on the different generations of a JVM Heap? I'm looking into a potential memory leak and need some data over the different generations. The use case I have is to take a snapshot over object in old generations, wait, and then take another snapshot to compare.

JVisualVM offers statistics over created object, but that doesn't help me much as I don't see whether or not a particular object is being promoted or tenured faster than it should.

Jmap offers statistics over the different generations, but not on an object basis. In that tool I can only see that the old generation is growing...

Run your app on Yourkit .It has got generation view tab.You can take snapshots of your heap and compare what objects are still alive between snapshots .
