Published online: 7 October 2025
Efficient, ideally fully automated, software package building is essential in the computing supply chain of the CERN experiments. With Koji, a very popular software building system used in the upstream Enterprise Linux communities, CERN IT provides a service to build software and images for the Linux OSes we support. Due to the criticality of the service and the limitations in Koji’s built-in monitoring, the CERN Linux team implemented new functionality to allow integration with Prometheus, an open-source monitoring system and time-series database. This contribution will give an overview of Koji and its integration with Prometheus and Grafana, explain the challenges we tackled during the development of the integration, and how we’re benefiting from these new metrics to improve the quality of the service.
