[Linux Ubuntu] How to Check CPU Utilization

Make sure you follow the steps explained in previous post :). Using sar, we can also monitor CPU utilization per second. Just press Ctrl+Alt+T to open Terminal and here is the command line to check CPU utilization per second:

sar -u 1

If you want to know CPU utilization in current second, just add one parameter behind like this:

sar -u 1 1

And it's done!
