nload is a command-line tool used for monitoring network traffic and bandwidth usage in real-time. It will display the incoming and outgoing traffic using two graphs. This console-based application also displays info like the total amount of transferred data and min/max network.

In this post, we will show you how to install and use nload to monitor network bandwidth usage in real-time.

Prerequisites

  • A Linux server on the Atlantic.Net Cloud Platform
  • A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Ubuntu, CentOS, or Rocky Linux as the operating system with at least 2GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your server, run the following command to update your base system with the latest available packages.

dnf update -y

Step 2 – Install Nload

For CentOS or RHEL operating system, install nload using the following command:

yum install epel-release -y
yum install nload -y

Step 3 – Use Nload to Monitor Network Usage

You can use the -m flag with nload command to display network usage of all network interfaces.

You can use the -t flag to sets the refresh interval of the display in milliseconds.
