1. A system for baseboard management controller (BMC) operation, the system comprising: 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 disposed in signal communication with the computing system, the BMC being bootable and operative independent of an execution of the operating system and which, upon boot initialization: includes a reserved database that is empty; issues to the computing system a first query for a list of the sensors and a second query for a list of sensor attributes for each of the sensors listed in the 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 first and second queries and sensor attribute data associated with the sensor data.
