Grafana is a free and open-source monitoring system that is used for monitoring and visualizing metrics from host machines. It provides intuitive and appealing dashboards, and analytics coupled with the ability to customize your own dashboards for monitoring your infrastructure. In this guide, we will show you how you can install Grafana on Ubuntu 18.04 and Debian 8. Let’s dive in.
Step 1: Update the system
The first step in installing Grafana is to update system repositories. Log in as a sudo user using SSH and execute the following commands.
# sudo apt update -y
Next, upgrade the system
# sudo apt upgrade -y
Step 2: Add Grafana APt repository
The next step will involve adding Grafana’s APT repository.
For Ubuntu 18.04
