What is Grafana?:

Grafana is an open-source data visualization and monitoring tool used for analyzing and monitoring time-series data. It provides a rich set of features and a flexible and customizable platform for creating interactive dashboards and graphs. Grafana supports a wide range of data sources, including popular databases like MySQL, PostgreSQL, and Prometheus, as well as cloud services like AWS CloudWatch and Google Analytics.

With Grafana, you can connect to various data sources, query the data, and create visually appealing and informative dashboards. It offers a web-based interface that allows users to build and configure their dashboards using a drag-and-drop approach. You can add different panels to a dashboard, such as graphs, tables, or gauges, and customize them with various visualization options and settings.

Grafana also supports alerting and notification features, allowing you to set up alerts based on defined thresholds or conditions. When a threshold is breached or a condition is met, Grafana can send notifications via email, Slack, PagerDuty, or other messaging platforms.

Overall, Grafana is widely used in the field of DevOps and system monitoring to monitor infrastructure, applications, and services, providing real-time insights into the performance and health of systems. It is highly extensible and has a large community of contributors, which ensures continuous development and integration with various data sources and technologies.

Environment Specification:

We are using a minimal Rocky Linux 9 virtual machine with following specifications.

CPU – 3.4 Ghz (2 cores)
Memory – 2 GB
Storage – 20 GB
Operating System – Rocky Linux release 9.2 (Blue Onyx)
Hostname – grafana-01.centlinux-com.preview-domain.com
IP Address – 192.168.116.133/24

Prepare your Rocky Linux Server:

By using a ssh client, login on your Linux server as root user.

Set a fully qualified domain name (FQDN) for your Linux machine as follows.

# hostnamectl set-hostname grafana-01.centlinux-com.preview-domain.com

Update software packages in your Linux OS by using dnf command.

# dnf update -y

If the previous command updates your Linux Kernel, then you should reboot your machine with the newly installed Kernel.

# reboot

Note down the versions of Linux OS and Kernel that are being used in this tutorial.

# cat /etc/rocky-release
Rocky Linux release 9.2 (Blue Onyx)

# uname -r
5.14.0-284.11.1.el9_2.x86_64

Add Grafana Official Yum Repository:

You can download Grafana software from their official website and GitHub. But the preferred method for Red Hat Linux distros is to add their official yum repository and then install Grafana data visualization software by using dnf command.

Create a .repo file by using vim text editor.

# vi /etc/yum.repos.d/grafana.repo

Add following directives in this file.

[grafana]
name=grafana
baseurl=https://rpm.grafana.com
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://rpm.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
exclude=*beta*

After adding Grafana repository, rebuild your yum cache.

# dnf makecache
