    DESCRIPTION
        "This MIB module augments the entPhySensorTable of 
        ENTITY-SENSOR-MIB to provide threshold information for 
        various sensors in the system. For example, a given device
        may have several voltage sensors as well as temperature
        sensors each with appropriate threshold support to help
        NMS systems detect and alert appropriately.

        In addition, on systems where it is supported, if the 
        sensor value crosses the supported threshold value the system
        can generate appropriate notification as well."
