How to Calculate CPU utilization in Linux

Here’s how to check CPU utilization in Linux. CPU usage is calculated using top command

$ top

You will see an output like the one below.

In it, you will see a line %Cpu(s)… This contains CPU utilization values. Among them CPU idle time = 81.7% (with id suffix after it).

CPU Utilization = 100 – CPU idle time

In our case,

CPU utilization = 100 – 81.7 = 18.3%

You can also use other utilities like mpstat, sar and iostat to find CPU utilization.


Hopefully, this article will help you calculate CPU utilization in Linux.
