You should check out jvisualvm which comes with any recent HotSpot
JVM. I don't have a copy available on the laptop I'm on right now,
but by looking at the screenshots, it looks like it shows the
permanent generation:

by the way, do you know *any tool that can monitor the permanent
generation*, such what's now resident in the perm gen?
I presume you mean on Windows, since you already found one for
Linux. I
suspect the more sophisticated profilers like YourKit will do it,
but I'm
not sure. Others on the list use YourKit regularly, so they might
be able
to be more definitive when they wake up in an hour or two.
