Checkmk
- +Rule-based configuration scales far better than per-host definitions
- +Free Raw edition is genuinely capable rather than a limited trial
- +Distributed monitoring is a first-class feature, not an add-on
- −Enterprise features including advanced reporting sit behind paid editions
- −Smaller community than Zabbix or Nagios, so fewer third-party templates
Best for Teams wanting a modern open-core platform that scales without per-device cost
Watch out Confirm which features you need are in Raw before assuming the free edition suffices
Zabbix
- +Genuinely free with no device or metric ceiling at any scale
- +Proxies allow distributed collection across sites and network boundaries
- +Very flexible templating and trigger logic once you understand the model
- −Steep initial learning curve — the configuration model is powerful but unintuitive
- −Database sizing and housekeeping become a real operational job at scale
Best for Engineering-capable teams wanting unlimited scale with no licence cost
Watch out Budget engineering time, not licence budget — that is where the cost actually lands
