A management subsystem and method for discovering management device functions. A management subsystem includes a system controller coupled to a plurality of devices each configured to monitor system resources and a non-volatile storage device via a first communication path. The non-volatile storage device may store a plurality of functions associated with the devices. The system controller may access the non-volatile storage device during initialization and create a function list including assigning a unique identifier to each of the functions. The system controller may transmit the function list via a second communication path in response to receiving a request for the function list. Further, the system controller may obtain system management information from one of the devices by invoking a particular one of the functions in response to receiving a request including a particular unique identifier corresponding to the particular one of the functions.
