If I set -Xms128m -Xmx128m for an application server how do I constantly track if I have enough heap size?

I'm using windows. So, using windows' peformance tracker, I'd only get 128mb as the allocated memory.

If you use the -verbosegc JVM option, the JVM will write the heap utilization before and after garbage collection to stderr.
