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.

Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.<br /> <br />#:^P
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
