Editor to share with you the use of iostat commands in linux to monitor the use of system input and output devices and CPU. I hope you will gain a lot after reading this article. Let's discuss it together.

Iostat is used to monitor the use of system input and output devices and CPU. It is characterized by reporting disk activity statistics as well as CPU usage.

[root@linuxcool ~] # iostat-d 2

Report every 2 seconds for 6 times:
