February 2026 monthly summary for facebook/fboss rackmon integration: Delivered telemetry and device-management improvements across Rackmon integration. Implemented Rackmon CLI Data Retrieval Enhancements with unit display, sensors filter, and robust latest data behavior; centralized register maps and added unit reading from maps; improved device addressing and lookup with DeviceLocation as the new key and ensuring uniqueDevAddress; added flag registers access and RS485 flags to improve monitoring of serial interfaces; standardized 0x prefix in addresses; refreshed BBU/PSU register maps, added sensor units; performed code cleanup and targeted bug fixes to stabilize tests and behavior. These changes enhance data accuracy, observability, and multi-bus device identification, enabling faster troubleshooting and more reliable rackmon2 telemetry in OpenBMC environments.
