Observium review
A mature self-hosted monitor with broad network coverage and unlimited-device plans.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Observium is a self-hosted network monitoring and management platform for network administrators and IT teams. It automatically discovers supported devices, services, and metrics, then presents web-based status views with real-time and historical performance data. Its scope covers home labs, small businesses, large enterprises, and service providers, with support for unlimited monitored devices, ports, and sensors across its editions.
The Community edition is open source and includes twice-yearly releases. Professional costs £250 per year with annual billing and adds daily software updates and fixes, plus threshold and traffic accounting systems. Enterprise costs £1,500 per year and adds additional support with 10 hours of included support time. All three editions retain unlimited monitored devices, ports, and sensors, making the paid tiers more about update cadence, accounting features, and support than capacity.
Observium’s feature set is broad for network-focused monitoring: automatic discovery, performance metrics, rule-based threshold, state, and syslog alerting, bandwidth tracking, LLDP/CDP topology maps, and ping and service probes for non-SNMP hosts. Routing coverage includes BFD, IP SLA, QoS, BGP, OSPF, and EIGRP. Integrations include collectd, munin, smokeping, RANCID, team-chat services, Telegram, webhooks, SMS providers, and Pushover. Choose Observium when unlimited-device self-hosting and network depth matter; consider another option if you prefer a hosted service or a narrower setup and maintenance burden.
