Load average – is the average system load calculated over a given period of time of 1, 5 and 15 minutes.System load/CPU Load – is a measurement of CPU over or under-utilization in a Linux system the number of processes which are being executed by the CPU or in waiting state.In this article, we will explain one of the critical Linux system administration tasks – performance monitoring in regards to system/CPU load and load averages.īefore we move any further, let’s understand these two important phrases in all Unix-like systems:
