This object reports the CPU utilization percentage of a board or entity averaged over the trailing one minute, smoothing out momentary spikes seen in an instantaneous reading. An admin uses this to judge whether high CPU usage is a brief blip or a sustained trend over the last minute. For example, hwAvgDuty1min reading 92 while the instantaneous figure fluctuates would tell an admin the board has been consistently near its CPU ceiling for the last minute, not just experiencing a momentary spike.
