When to prefer Zabbix

You want the most mature open-source infrastructure monitoring system with the largest community template catalog, SQL-backed history, and deep customization. Zabbix has been a sysadmin staple for two decades.

When to prefer Checkmk Raw

You want strong auto-discovery and lower configuration overhead out of the box. Checkmk's auto-discovery and rule-based configuration make it faster to stand up for shops that don't want to hand-build dozens of templates.
