Step-by-Step Guide to Install and Configure Zabbix 4.4 on CentOS 8

Zabbix Overview

Zabbix is an open‑source, web‑based enterprise solution for distributed system and network monitoring. It monitors various network parameters, ensures server security, and provides flexible notifications to help administrators quickly locate and resolve issues, reducing operational workload.

It consists of an Agent side that collects data from hosts and a Server side that stores data in a database (MySQL, Oracle, etc.) and displays it via a PHP‑Apache web front‑end.
