What is Zabbix?

Zabbix is an open-source enterprise monitoring solution used to monitor IT infrastructure such as:

Servers (Linux, Windows)

Networks (routers, switches, firewalls)

Applications

Databases

Cloud services

Virtual machines and containers

It helps teams detect problems early, analyze performance, and respond to incidents before they impact users.

Why Zabbix Is Used

Monitor system health in real time

Detect failures automatically

Reduce downtime

Centralize monitoring in one dashboard

Alert admins before systems go down

Used by small companies to large enterprises.

Zabbix Architecture (Core Components)

Zabbix Server

The heart of Zabbix

Collects monitoring data

Evaluates triggers

Sends alerts

Stores data in a database

Zabbix Agent

Installed on monitored systems.

Collects metrics (CPU, RAM, disk, processes)

Sends data to Zabbix Server

Two types:

Passive Agent – server asks agent

Active Agent – agent sends data automatically

Database

Stores:

Configuration data

Historical metrics

Events and alerts

Supported DBs:

MySQL / MariaDB

PostgreSQL

Oracle

Zabbix Frontend

Web-based GUI

Dashboards

Graphs

Alerts

Configuration

Accessible via browser.

Zabbix Proxy (Optional)

Used in distributed environments

Collects data from remote locations

Reduces load on main server

Works even if WAN link is down
