esaProbeDistStatsConfigType is a read-only EsaProbeDistStatsType indicating which specific metric this distribution row covers: round-trip delay, one-way probe-to-reflector delay, one-way reflector-to-probe delay, probe-to-reflector jitter, or reflector-to-probe jitter. An administrator reads this to know exactly which performance metric's histogram bins they are about to configure or inspect via the sibling min/max/bin-boundary objects in the same row. For example, a technician wanting to build a custom histogram of one-way reflector-to-probe delay locates the row where this type reads oneway-r2pdelay before touching any of that row's bin-boundary settings.
