Define Your Monitoring Strategy

Decide what you want to monitor:

• Servers (Linux, Windows, VM, Cloud)
• Network devices (Routers, Switches, Firewalls, Access Points)
• Applications (Databases, Web Apps, APIs)
• Logs & Metrics (CPU, Memory, Bandwidth, Security Events)

Monitor Servers with Zabbix Agent

Install Zabbix Agent 2 on all your servers (Linux/Windows) for detailed monitoring.

Linux Installation
