An apparatus and a method are disclosed for tracking use of a specialized hardware component in symmetric multiprocessing computing device. A device includes a memory and one or more multi-core processors attached to a coherent memory bus. A proxy for a specialized hardware component (SHC) such as an accelerator, FPGA, or ASIC is placed in communication with the coherent memory bus. The proxy may be attached to another bus such as a peripheral component interconnect express (PCIe) bus. A tracker updates an allocated counting register with counts of events related to use of the SHC. When requested, information from the counting register is provided such as to an external device or client communicating with the multiprocessing computing device. The tracker may follow calls or messages to the SHC. The tracker may accumulate a count of message size or mode of use or use of certain functions of the SHC.
