How To Fix diskdevstat: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu diskdevstat is provided by tuned-utils-systemtap package.

tuned-utils-systemtap is:

The tuned package contains a daemon that tunes system settings dynamically. It does so by monitoring the usage of several system components periodically. Based on that information components will then be put into lower or higher power saving modes to adapt to the current usage. Currently only ethernet network and ATA harddisk devices are implemented.

This package contains several systemtap scripts to allow detailed manual monitoring of the system. Instead of the typical IO/sec it collects minimal, maximal and average time between operations to be able to identify applications that behave power inefficient (many small operations instead of fewer large ones).

To fix this problem, we can install more using the command below.

sudo apt-get -y install tuned-utils-systemtap

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install tuned-utils-systemtap.

sudo apt -y install tuned-utils-systemtap
