Sometimes you may want to know the CPU usage of a particular Linux process. As the CPU usage of a process can fluctuate over its lifetime, you will want to measure the average CPU usage or CPU utilization of the process to set a baseline.
For this purpose, a Linux tool set calledsysstatmay come in handy.sysstatcontains a collection of performance monitoring tools for Linux, reporting statistics on disk I/O, CPU, memory, networking, and other system activities. This tutorial demonstrates how to measure the average CPU utilization of a particular Linux process, or process-level CPU usage of all available Linux processes.
