This is the collectionInterval property of a stats collection policy, the cadence at which UCS Manager samples the underlying performance counters for the statistics domain this policy governs. An admin tunes this interval to balance monitoring granularity against overhead, shortening it to catch transient spikes or lengthening it to reduce the sampling load on the fabric interconnects. For example, setting a short collectionInterval on the policy covering chassis power stats lets an admin see a brief power draw spike that a longer interval would average away.
