Developed and integrated new power monitoring sensors for Raritan PDUs within the librenms/librenms repository, focusing on enhancing device monitoring and configuration management. Leveraged SNMP and YAML to define and validate new OIDs, enabling accurate tracking of power consumption and overcurrent protectors. Improved monitoring reliability by refining pre-cache handling, ensuring sensor data remained current and precise. Enhanced sensor metadata with SNMP flags, which strengthened dashboard accuracy and alerting capabilities. These updates provided greater visibility into critical power metrics, supporting proactive capacity planning and faster incident response, while also improving the overall quality and maintainability of the monitoring system.
