Garbage Collection

One of the other essential tasks regarding the JVM is monitoring. How much stack and heap is your JVM using? What CPU saturation are you using? How many threads are being used, and what kind of threads are being used? What is your garbage collector looking like? How can I tap into the JVM and monitor other aspects of the JVM? All these questions are essential to ask since often administrators of your Java application will need to know these values to deploy and monitor your application.
