A system for baseboard management controller (BMC) operation is provided. The system includes a computing system including hardware on which an operating system is operable and sensors disposed to sense various attributes of the hardware and a BMC. The BMC is disposed in signal communication with the computing system and is bootable and operative independent of an execution of the operating system. Upon boot initialization of the BMC, the BMC includes an empty reserved database, issues to the computing system a query for a list of the sensors and builds and populates in the reserved database a sensor attribute repository in accordance with sensor data received from the computing system in response to the query and sensor attribute data associated with the sensor data.
