Use this page to specify the frequency of receiving events as a filtering criterion.
For duplication event filters, the Interval field can be used without using the Count field (Count = 0). The first occurrence of an event that meets the criteria triggers associated actions and starts a countdown of the units that define the interval. For example, if you enter 10 and select seconds, a 10-second timer starts when an event meets the filtering criteria. If Count is set to 0, all other instances of an event that meets the criteria do not trigger associated actions during the interval.
If Interval is set to a value greater than 0, and Count is set to a value greater than 0, after the first occurrence of an event meets the filtering criteria, the value entered in the Count specifies the number of times an event must meet the criteria within the interval before associated actions can be triggered again. For example, if you set Count to 9, an event meeting the criteria must occur nine times within the interval. When an event meets the criteria for a tenth time within the interval, associated actions are triggered, the count is reset, and the interval is reset.
For threshold event filters, the Interval field must be used in conjunction with the Count field. Interval specifies a window of time that begins when an event meets the filtering criteria. The first occurrence of an event that meets the criteria does not trigger associated actions, but starts a countdown of the units that define the interval. For example, if you enter 10 and select minutes, a 10-minute timer starts when an event meets the filtering criteria. The value entered in Count specifies the number of times an event must meet the criteria before associated actions are triggered. For example, if you set Count to 9, the first 8 events matching the criteria that occur within the interval do not cause associated actions to trigger. The ninth time an event meets the criteria within the interval, associated actions are triggered, the count is reset, and the interval is reset.
