CentOS / RHEL: Install atop (Advanced System & Process Monitor) Utility

by

The atop utility is an advanced system and process monitor for Linux that provides detailed information about system resource utilization. To install atop on CentOS or Red Hat Enterprise Linux (RHEL), you can follow these steps:

  1. Add the EPEL repository: atop is not included in the default CentOS/RHEL repositories, so you’ll need to add the Extra Packages for Enterprise Linux (EPEL) repository to your system. To do this, run the following command:
sudo yum install epel-release
  1. Install atop: Once the EPEL repository has been added, you can install atop by running the following command:
sudo yum install atop
  1. Start atop: To start the atop utility, simply run the following command:
sudo atop

This will launch the atop interface, which provides real-time information about system resource utilization, including CPU usage, memory usage, disk I/O, network usage, and process-level details.

Note: atop is a powerful utility, and it can produce a lot of information. Be sure to familiarize yourself with its features and options before using it, as it can be overwhelming to new users.
