openITCOCKPIT is an open source monitoring platform that serves as a configuration and visualisation web frontend for Naemon, Nagios and Prometheus. It uses the Naemon monitoring engine, which is described as fully compatible with Nagios, and adds graphical configuration of Prometheus exporters and alert rules. A cross-platform agent for Windows, Linux and macOS covers CPU, memory, disk, network, services, processes and Docker, with encrypted communication in pull and push modes. Further features include dashboards, Grafana integration, SLA and availability reports, event correlation into business services, and integrations with tools such as ServiceNow, Slack and PagerDuty.
The product comes from AVENDIS GmbH in Fulda, Germany. A Community Edition is available as open source, and a subscription-based Enterprise edition adds further integrations. The platform is downloaded and installed on your own servers, with updates through the Linux distribution's package manager, so monitoring data stays within your own infrastructure. The vendor's pages do not name the specific open source licence, which is worth checking before adoption.
