Hi,

Can somebody please answer these questions.

1. I see the following statistics listed for process with PID 3905

Statistic for  '3905-257.288103298' :

cpu time :           0.114179414
events count :  2091
elapsed time (includes per process waiting time) :           8.745760749
cumulative cpu time (includes nested routines and modes) :           1.669448492

Shouldn't the cumulative cpu time be greater than the sum of cpu time and elapsed time.

Can somebody explain what these values mean.

2.  I see the Birth Sec for init to be 257 on my trace data ( I probably started the trace at 256th sec)

Can somebody tell me what the Birth sec for each process means here.

Thanks,
Ashwin
