This read-only object reports the mean, or average, of all the values sampled in this histogram, expressed as a fixed-point value needing the associated scale and precision to read correctly. It gives an admin a single representative figure for the overall behavior of the tracked parameter across the whole collection period, complementing the min and max extremes. For example, comparing p2mpHistMean against p2mpHistMin and p2mpHistMax together tells an admin whether a link's signal quality is consistently poor or just occasionally dipping.
