Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Checkmk is an infrastructure monitoring and observability platform for IT teams managing on-premises, cloud, hybrid, and containerized environments. It discovers hosts and services, collects status and performance data, and provides dashboards, alerting, reporting, automation, historical data, and integrations. Coverage includes servers, networks, storage, VMware ESXi and vCenter, cloud services, Kubernetes, and applications through OpenTelemetry. Deployment options span self-hosted installations, web access, Linux, APIs, and a fully managed SaaS edition.
The freemium structure gives smaller environments a clear entry point. Community is free forever, open source, includes 2000+ pre-built integrations, scales to approximately 100 hosts, and comes with community support. Pro starts at €190 per month with annual billing and adds approximately 3,000 services at the displayed starting tier, advanced analytics and reporting, distributed monitoring, and professional support available 8 hours by 5 days. Ultimate costs €275 per month with annual billing and adds full-stack observability, advanced cloud integrations, automated mass rollouts, and support available 10 hours by 5 days. Cloud is fully managed, AWS-hosted, supports up to 50,000 services, and offers US or EU hosting regions.
Checkmk fits teams that need one monitoring layer across mixed infrastructure and want automatic discovery, centralized automation, or flexible collection methods. Agent-based monitoring covers Linux, Windows, and other operating systems, while agentless options include SNMP, TCP/UDP, IPMI, WMI, and Redfish. Integrations with ServiceNow, Jira, Slack, AWS, Microsoft Azure, Google Cloud Platform, VMware, Kubernetes, and flexible APIs support operational workflows. Teams wanting a free starting point can choose Community; organizations needing distributed monitoring, managed hosting, or advanced observability should consider the corresponding paid edition.
