Comparisons anchored on Checkmk, Checkmk GmbH's monitoring platform with a free GPL Community edition and paid Pro, Ultimate and Cloud editions.
What each Checkmk edition includes and costs: free Community on the Nagios core for about 100 hosts, Pro with the Checkmk Micro Core, distributed monitoring and support, and Ultimate with multi-tenancy and push agents, at the published monthly prices.
Two Nagios-descended platforms compared: Checkmk's auto-discovery and rule-based setup against Icinga 2's DSL and Director, on scale limits of the free editions, paid features, agents, distributed monitoring and vendor support.
Checkmk's SaaS Cloud edition, capped at 50,000 services, against self-hosted Community, Pro or Ultimate: published prices, service limits, features and add-ons, data location and the work of running the monitoring server yourself.
