Please log in for more thread options Thanks Paul ...
In order to get the CPU usage in percentage, I will be using the following
Algorithm:
T1, T2, Tn are threads of their respective processes P1, P2, Pn etc.
=========================================
Time_P1 = (GetThreadTimes(T1)+GetThreadTimes(T2)+ ..... GetThreadTimes(Tn))
;
Time_P2 = (GetThreadTimes(T1)+GetThreadTimes(T2)+ ..... GetThreadTimes(Tn))
;
.
.
.
Time_Pn = (GetThreadTimes(T1)+GetThreadTimes(T2)+ ..... GetThreadTimes(Tn))
;
Total Time Consumed (lets call this: TTC) = Time_P1 + Time_P2 + ...... +
Time_Pn ;
CPU Usage for P1 = (Time_P1 / TTC) * 100 ;
CPU Usage for P2 = (Time_P2 / TTC) * 100 ;
.
.
.
CPU Usage for Pn = (Time_Pn / TTC) * 100 ;
=========================================
If you or any one else think, that this should be corrected, please let me
know.
Thanks,
