This object reports the highest utilization value this specific dataplane resource has ever reached, distinct from its current live measurement reported elsewhere in this row. This historical high-water mark is useful for capacity planning, since it can reveal that a resource came dangerously close to its threshold at some past peak even if the current reading looks comfortably low today. For example, a maximum recorded value of 4,090 against a 4,096 threshold reveals a near-miss during some past traffic spike that the current, lower reading alone would never show.
