This sets, in minutes, how much time each of the fixed 96 CCM-loss history buckets covers for this service, with a default of 15 minutes per bucket meaning the full 96-bucket history spans a rolling 24 hours. An admin adjusts this to trade off historical time-range coverage against granularity: shortening the interval gives finer resolution but covers less total time within the fixed 96 buckets, while lengthening it extends the covered history at the cost of coarser detail per bucket. For example, changing this from the 15-minute default to 30 minutes would double the covered history to 48 hours, but each bucket would then blend together twice as much CCM loss activity, hiding short-lived loss spikes that a 15-minute bucket would have isolated.
