Note that you'll need a pre-release build of JDK7 to use these static
probes - they are no available in JDK6 or earlier.

Hi Ajit,
You can add static dtrace probes into your code, to get a accurate
measure of time spent in the 'real CPU intensive' section of the code.
eg.,
DTRACE_PROBE_START
<code snippet to time>
DTRACE_PROBE_END
For adding probes in your java application see,

Hi,
I need help in calculating Java method time-stamp in following fashion.
Consider following method example.
long method3(long stop) {
try {
Thread.sleep(1500);
} catch (Exception e) {
}
//////////////////// real CPU intensive operation ///////////////////////////
for (int i = 1; i < stop; i++) {
stop = stop * stop * i;
};
return stop;
}
For above method, I can get time-stamp by using "vtimestamp" and method-entry/return probes.
But I also want to how much time it is spending as idle ( in above case 1500
ms) and how much in real CPU intensive operation.
Is there any way to do this?
Help appreciated.
Thanks,
Ajit
