Analysis of CPU Usage Data Properties and their possible impact on Performance Monitoring

Konstantin S. Stefanov    
Alexey A. Gradskov    

Resumen

CPU usage data (CPU user, system, iowait etc. load levels) are often the basic data used for performance monitoring. The source of these data is  the operating system. In this paper we analyze some properties of CPU usage data provided by Linux kernel. We examine kernel source code and provide test results to find which level of accuracy and precision one may expect when using CPU load level data.
