Feb 1, 2025February 2025: DUNE-DAQ/drunc delivered significant enhancements to FSM monitoring via OpMon integration, enabling dynamic configuration and improved observability while reducing coupling to legacy opmon interfaces. Key work included implementing OpMon-based FSM monitoring with a publisher interface, reading OpMon URI from config, and supporting dynamic bootstrap servers and topics. Additionally, run-number actions were updated to use context session and application name for better traceability. A dedicated code cleanup pass resolved merge conflicts and refined imports/usages to ensure clean integration and maintainability.
