Full-Stack Monitoring and Observability for Hybrid IT

Visit Checkmk

Checkmk is a full-stack monitoring and observability platform for hybrid IT environments. It discovers and monitors servers, networks, storage, cloud workloads, containers, and applications from a single platform, using automated discovery and flexible data collection methods including agent-based, agentless, and SNMP or REST-API approaches. It supports distributed and multi-tenant deployments, with dependency mapping, dashboards, advanced analytics, and SLA and availability reporting.

Key capabilities include a catalog of more than 2,000 pre-built integrations, native OpenTelemetry integration for application observability, synthetic monitoring powered by the Robot Framework, and the Agent Bakery for centralized agent management. AI features include Explain with AI for root cause summaries and the Checkmk MCP server, which connects external AI tools to live monitoring data under read-only access. Integrations cover ITSM, chat, and ticketing tools such as ServiceNow, Jira, and Slack, alongside flexible APIs.

Checkmk is offered in four editions: Community, a free and open-source option for small infrastructures; Pro and Ultimate, self-hosted editions for data center and hybrid environments; and Cloud, a fully managed SaaS edition. Pricing is based on hosts and services, and a free trial is available for the Cloud edition.
