How Zabbix Works and Architecture

How It Works:
Zabbix collects performance data from monitored devices and compares it against predefined thresholds. Alerts are triggered when these thresholds are breached, and data is stored for analysis and visualization.

Architecture Overview:

1. Zabbix Server:
   Acts as the core of the system, responsible for data collection, storage, and processing.
2. Database:
   Stores configuration data, metrics, events, and historical data for analysis.
3. Zabbix Agents:
   Installed on monitored devices to collect detailed metrics and send them to the Zabbix server.
4. Proxies:
   Used to scale monitoring by offloading data collection and preprocessing in distributed environments.
5. Frontend (Web Interface):
   Provides a user-friendly dashboard for configuring monitoring, visualizing data, and managing alerts.
6. Alerting System:
   Configures triggers and actions to notify users of critical issues.
