Checkmk

Overview

Checkmk is an infrastructure and network monitoring platform offered in self-hosted and SaaS editions. Its free Community edition covers up to about 100 hosts with community support^[15]. Paid self-hosted editions are Pro, from €190 per month billed annually (equivalent to about 3,000 services, or as low as about €1.90 per host per month) with 8×5 support, and Ultimate, from €275 per month with 10×5 support; Ultimate is described as suited to multinationals and MSPs and has a separate multi-tenancy trial build^[15].

Checkmk Cloud, the SaaS edition, costs €240 per month at 1,000 services, about €7.20 per host per month assuming 30 services per host, and scales to 50,000 services^[15]. Pricing by service, rather than by device, rewards organisations that monitor a moderate number of metrics per host.

All paid editions have 30-day trials; when a self-hosted trial expires the installation continues in a free mode limited to 750 services and one site^[15]. The breadth of editions and options takes time to evaluate, and service-based licensing requires an estimate of services per host. Prices are published in euros^[15].
