Zabbix is enterprise monitoring from the pre-Kubernetes era — agent-based polling, SQL-backed (MySQL/PostgreSQL), with a mature web UI that covers metric collection, threshold alerting, network discovery, SNMP, and IPMI. Still under active development by Zabbix LLC out of Latvia.
Pick it if: you run physical/network infrastructure (switches, UPS, hypervisors, bare metal) where SNMP and IPMI matter, or you want a single tool that covers monitoring + alerting + inventory without assembling a Prometheus stack. Strong fit for NOCs and MSPs.
Skip it if: your environment is cloud-native and ephemeral — Zabbix’s host-and-template model fights short-lived containers. Prometheus and the OTel ecosystem are a more natural fit for k8s-first workloads.
Deployment: RPM/DEB packages on Linux, official Docker images, and a Helm chart. Pair with a managed Postgres or MySQL for the backing store. Web UI is PHP.
