What it is
Zabbix is a free, open-source monitoring system for servers, network equipment, virtual machines and applications. It collects metrics, draws graphs and network maps, and raises alerts, giving one place to watch an entire infrastructure.
Problems it solves
- You need one monitoring system across servers, SNMP devices and applications without per-node fees.
- Alerting must escalate to the right people with clear context.
How administrators use it
- Deploy agents and SNMP checks, then group hosts into templates for consistent metrics.
- Build trigger expressions and escalation chains so on-call gets paged on real failures.
- Publish network maps and dashboards for a shared operational view.
Strengths & trade-offs
Strengths
- Free and genuinely enterprise-capable.
- Templates, SNMP, auto-discovery.
- Active community and long-term support releases.
Trade-offs
- Steeper learning curve.
- You host and scale it yourself.
Questions
Does Zabbix cost anything?
