Zabbix
Pros
- + Free, no per-host or per-seat licensing — cost stays flat as monitored infrastructure grows
- + Deep protocol coverage: agent2, SNMP, IPMI, JMX, HTTP, synthetic checks, Kubernetes
- + 25 years of field-hardened releases with a disciplined LTS support schedule (7.0 LTS to June 2029)
- + Zabbix Cloud removes the ops burden without changing the tool; 5-day trial without a credit card
- + Open source under AGPLv3 with a documented API, Terraform provider and large template ecosystem
Cons
- - Steep learning curve — configuration UI, trigger syntax and template design need real investment
- - Zabbix Cloud drops values at random above the NVPS cap and disk only grows (once per 24h, never shrinks)
- - No published numeric uptime SLA or public region list for Zabbix Cloud; compliance certifications still in progress
- - Weaker on logs and distributed tracing than modern observability suites; self-hosting means you own the upkeep
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
