Lin­ux Serv­er

There is a cou­ple of tools avail­able that al­lows you to mon­i­tor and an­a­lyze the disk I/O per­for­mance of your Lin­ux dri­ven sys­tem. Here are list­ed few of them and al­so how to in­stall and ex­am­ples of their ba­sic us­age.

Htop 3.2+

If the lat­est ver­sion of htop is avail­able at your dis­tri­b­u­tion, there is avail­able an ad­di­tion­al tab that shows the I/O met­rics of the in­stance – Screen 1. Here is how to check the avail­able ver­sion and in­stall htop. 

sudo apt show htop 2>/dev/null | grep '^Version'

sudo apt install htop

In­stall the lat­est ver­sion of htop 3.2.1–1 on Ubun­tu Serv­er 22.04.1 from a .deb pack­age.

cd /tmp
wget --no-check-certificate https://http.us.debian.org/debian/pool/main/h/htop/htop_3.2.1-1_amd64.deb
sudo apt install ./htop_3.2.1-1_amd64.deb

To be able to see all da­ta in most cas­es you need to run the tool as root:

sudo htop
