[jboss-dev-forums] [Design of JBoss Profiler] - Re: How CPU utilization is worked out in the analysis?

The CPU is calculated over the clocks counter over GetCurrentThreadCPUTimer. http://java.sun.com/j2se/1.5.0/docs/guide/jvmpi/jvmpi.html#GetCurrentThre... The logger will write the Timer when the method is in, and out.. and during the calculation (or processing) this is stacked and calculated. Say... When you stack calls, Method A will call Method B, C and D. Say.. .if method A took 100 Milliseconds on the CPU Timer, than B. C and D took 50, 40, and 10 Milliseconds, each one will be 50%, 40% and 10%. (Simple calculation) Notice that sometimes Method A itself will consume CPU, so you won't have B+C+D=100% all the time.
