Andreas Brunnert enhanced process monitoring in the sustainable-computing-io/kepler repository by developing a feature that improves identification of KVM virtual machine processes within Proxmox environments. He updated regular expression patterns in Go to more accurately detect KVM processes, addressing gaps in previous detection logic. To ensure reliability and prevent regressions, Andreas expanded the test suite, focusing on comprehensive backend testing. This work enables more precise automation, alerting, and root-cause analysis for Proxmox KVM deployments. The depth of his contribution is reflected in the careful refinement of detection logic and the robust test coverage, supporting maintainable and reliable backend operations.
