Unified monitoring for servers, containers, and cloud workloads
Checkmk delivers scalable, low‑resource IT monitoring across physical, virtual, container and cloud environments, offering a free Raw edition and advanced Enterprise/Cloud features for automation and dashboards.
Checkmk is a comprehensive IT monitoring platform that works across on‑premise servers, virtual machines, containers, and major public clouds. It targets system administrators, DevOps teams, and managed service providers who need a single solution for infrastructure and application observability.
The core engine provides agent‑based and agentless data collection, a web UI, and hundreds of plugins. The free Raw edition supplies the essential monitoring stack, while Enterprise adds distributed monitoring, built‑in dashboards, automated agent management, and integrations such as LDAP and REST APIs. Cloud‑focused editions extend support to Kubernetes, AWS, Azure, and GCP, leveraging OpenTelemetry, push agents, and auto‑registration. Installations are available as native DEB/RPM packages for major Linux distributions, Docker containers, or as virtual/physical appliances, giving flexibility for on‑prem or SaaS deployments.
A vibrant community contributes additional plugins, and the platform’s modular architecture allows custom checks and dashboards, making it adaptable to diverse monitoring requirements.
