Step by Step guide to install Grafana on Rocky Linux 8 and other RPM based distros.

What is Grafana? :

Grafana is a multi-platform open source analytics and interactive visualization web application. It provides charts, graphs, and alerts for the web when connected to supported data sources. A licensed Grafana Enterprise version with additional capabilities is also available as a self-hosted installation or an account on the Grafana Labs cloud service. It is expandable through a plug-in system. End users can create complex monitoring dashboards using interactive query builders. Grafana is divided into a front end and back end, written in TypeScript and Go, respectively.

As a visualization tool, Grafana is a popular component in monitoring stacks, often used in combination with time series databases such as InfluxDB, Prometheus and Graphite; monitoring platforms such as Sensu, Icinga, Checkmk, Zabbix, Netdata, and PRTG; SIEMs such as Elasticsearch and Splunk; and other data sources. The Grafana user interface was originally based on version 3 of Kibana.

Grafana is licensed under an AGPLv3 license. Contributors to Grafana need to sign a Contributor License Agreement (CLA) that gives Grafana Labs the right to relicense Grafana in the future. The CLA is based on The Apache Software Foundation Individual Contributor License Agreement. (Source: Wikipedia)
