Netdata
Pros
- + Free Community tier is a real deployment: up to 5 active nodes with per-second metrics and local storage
- + Flat per-node pricing ($4.50/node/month billed annually on Business) — no ingest, cardinality, seat, or retention charges
- + Agent is open source (GPLv3+) with 80,000+ GitHub stars and 690+ contributors; data stays on your own infrastructure
- + 800+ integrations plus Prometheus, OpenTelemetry/OTLP, StatsD, SNMP, eBPF, and Nagios plugin support
- + ML anomaly detection runs in the agent at every metric, not as a paid add-on
Cons
- - Centralized dashboards cap at 5 nodes and custom dashboards at 1 per room on the free tier
- - RBAC, SSO, and SCIM require the Business tier even for small teams
- - No published uptime SLA for Netdata Cloud; priority support is an Enterprise On-Premise item
- - Operating at scale requires provisioning tooling (Ansible/Terraform-like) for consistent agent configuration
- - Dashboard customization is more limited than fully programmable alternatives; larger fleets effectively need Netdata Cloud
Oh Dear
Pros
- + Every feature on every plan — no tiering of SSO, status pages, users, or API access
- + Two-location verification before firing alerts, which genuinely reduces false alarms
- + One site slot replaces uptime, SSL, broken-link, DNS, cron and Lighthouse tools at a predictable per-site price
- + EU-hosted (Belgium, ISO 27001 infrastructure) with full API and strong agency/reseller workflow
Cons
- - No free plan and no single-site tier below €15/month
- - Website/server monitoring only — no APM, metrics, logs, or host-level observability
- - Small vendor (2–10 people) with no published SLA for the monitoring service itself
- - Per-site cost is above bare uptime checkers; 200 sites costs €399/month
