Historical CPU Usage

As noted above, we will use the sar command to view the historical statistics. The command is otherwise virtually the same, being sure to check the %idle column:

sar -p
Current CPU Usage

The real-time CPU usage can be viewed by running the top command. On the line that says Cpu(s), check the %id section to see the percentage at which your CPUs are idle; the higher the number, the better. A 99% idle CPU is doing almost nothing, whereas a 1% idle CPU is heavily tasked at that moment.
