More than once, we all had the idea of trying to find out what was going on in the bottom of a running program. This need may be due to slow service, Java Virtual Machine (JVM) crashes, hangs, deadlocks, frequent JVM pauses, sudden or persistent high CPU usage, and even terrible memory overflows (oome).
