C Program To Find Cpu Usage


We are not locking anywhere to Exit out of the lock are we? I would put usage of this inside some #ifdef so it's only used in Windows 2000/XP, because this method could change or be removed in future versions of Windows. I thought that number would just be the total property of the information provided by glibtop_cpu (as it seems to be user + nice + sys + idle, but it actually Do they wish to personify BBC Worldwide? http://smartnewsolutions.com/cpu-usage/c-program-high-cpu-usage.html

These can be used to measure the amount of CPU time taken between two time intervals. You could read utime or stime values at two distinct moments and compute the desired cpu utilization stats. (I guess top uses this raw data too.) (I forgot: this is linux Updated 2/4/2009: I changed the implementation of these classes from the original: Instead of a critical section, InterlockedIncrement/Decrement is used.

The critical section run count enables the code to be called in a multi-threaded environment without problems. If you have a copy of the Linux kernel source handy, look at fs/proc/stat.c, particularly the show_stat function. However, we still need the Win32 API call for getting the total system times (GetSystemTimes). Download the C++ and C# projects that accompany this article.
