11 . The non-transitory computer readable medium of claim 8 , further comprising:

selecting, by the event processor, a second event in the stream of events after the first event;

determining, by the event processor, that a parameter of the second event matches criteria for a non-skippable event; and

indicating, by the event processor, that the second event is non-skippable despite the rate exceeding the threshold limit over the time period.

12 . The non-transitory computer readable medium of claim 8 , further comprising:

determining, by the event processor for a second event in the stream of events after the first event, that the rate does not exceed the threshold limit over the time period; and
