esaProbeDistStatsConfigMaxVal is a read-write Integer32 setting the maximum sample value expected in this metric's distribution histogram. An administrator sets this to the largest value worth distinguishing for that metric, so that legitimate high (but not extreme) samples still land in a meaningful bin instead of all collapsing into a single overflow bin. For example, setting this maximum too low on a jitter-sensitive voice circuit would lump every jitter spike above that ceiling into one bin, making it impossible to tell a mild jitter problem from a severe one.
