Zabbix vs Prometheus
The two open-source escape routes, pointed at different worlds: Zabbix at traditional SNMP networks, Prometheus at cloud-native. Picking wrong here is the most common monitoring mistake.

| The catch | Power comes with a steep config burden — templates, items and triggers are fiddly, the UI is dense, and "free" means you're the integrator and operator carrying real ops overhead. | Single-node by design — no native HA or long-term storage — so any serious deployment becomes a 4-5 component stack (Alertmanager, Grafana, Thanos/Mimir, exporters) you assemble and operate yourself. |
Which should you pick?
Pick Zabbix if…
SNMP-heavy, multi-site networks and a single integrated tool that ships with a UI.
Full Zabbix profile →Pick Prometheus if…
Containers, Kubernetes, and config-as-code — accepting that "Prometheus" really means a multi-component stack you operate.

Zabbix or Prometheus for SNMP network monitoring?
Zabbix. It treats SNMP, ICMP and network devices as first-class citizens with discovery and templates out of the box. Prometheus monitors SNMP only via snmp_exporter, which works but is the clunky path — Prometheus is built for pull-based application and infrastructure metrics, not network gear.
Which scales better, Zabbix or Prometheus?
Both scale, differently. Zabbix scales vertically and through proxies for distributed polling. Prometheus scales by federation or by handing long-term storage to Thanos/Mimir/VictoriaMetrics. For Kubernetes and high-cardinality metrics, Prometheus’ model fits; for thousands of SNMP devices across sites, Zabbix’ proxy model fits.
