Installing and using iotop

iotop – a console program that displays statistics on the use of disk space.

You can install Debian, Ubuntu, Mint with the command:

sudo apt-get install iotop

In Red Hat, Fedora, CentOS:

yum install iotop

Normal startup:

iotop

Running with the option:

iotop OPTION

I’ll describe the possible startup options:
–version (view version)
-h (view help)
-o (display only active processes or threads that read or write, instead of displaying all)
-b (inclusion of non-interactive mode, convenient for example to output information to a file)
-t (display time in each line, for non-interactive mode -b)
-n NUMBER (the number of iterations after which the output will be executed, if not specified, then the output is not standardized)
-d NUMBER (the delay between iterations in seconds, you can specify not an integer, a standard value of 1)
-p PID (display statistics only for the specified processes / threads, standard for all)
-u USER (display statistics only for specified users, standard for all)
-P (display only processes)
-a (accumulation of statistics from the start of the launch of iotop)
-k (statistics in kilobytes)
-q (shortened view, some header lines are removed, when used with the -b option. There are more abbreviated, for example -qq without title names and -qqq without a general summary)
