Checkmk

About

Checkmk is a comprehensive IT monitoring and DevOps tool originating from Germany, available as a freemium and open-source solution. It offers extensive capabilities for monitoring servers, applications, networks, cloud environments (including AWS and Azure), containers, storage, databases (like Oracle), and IoT devices. The product portfolio includes a 100% pure open-source 'Raw Edition' and an 'Enterprise Edition' with additional features, though the Raw Edition has been noted to have a 25-host limit in recent versions. Key features encompass scalable and distributed monitoring, performance and uptime monitoring, downtime detection, automatic discovery, network mapping, and IT asset management. It supports a wide array of technologies such as SNMP, IPMI, TCP port monitoring, Linux, VMware, Kubernetes, Docker, NGINX, and Apache, and provides SLA monitoring and Grafana integration. Checkmk runs on Windows, Linux, and Docker platforms. Users find it easy to set up and operate, appreciating its rule-based configuration method for its flexibility, especially those familiar with Nagios. The company maintains an active presence on GitHub at https://github.com/tribe29/checkMK/ and on Twitter.
