Configuration Recommendations

If Number of Occurrences is set to 1, then set Period Type to Rolling day and Period to 1.
If Number of Occurrences is greater than 1, then Period Type and Period should be configured such that the effective lookback period is the lowest value that meets the requirement. Otherwise, there might be performance issues, as illustrated in the examples below.

Configuration examples
Requirement	Number of Occurrences	Period Type	Period	Comments
Trigger an incident every time there is an occurrence.	1	Rolling Day	1	The effective lookback period is one rolling day. This is the lowest value that meets the requirement.
Trigger an incident every time there is an occurrence.	1	Rolling Day	365	The effective lookback period is 365 rolling days. Although this configuration can work, the effective lookback period isn’t the lowest value that meets the requirement. To avoid performance issues, set the values as follows: Period Type = Rolling Day Period = 1 This setting will have an effective lookback period of one day, which is the lowest value that meets the requirement.
Trigger an incident if there are two occurrences within three days.	2	Rolling Day	3	The effective lookback period is three rolling days. This is the lowest value that meets the requirement.
	2	Rolling Week	2	The effective lookback period is 14 rolling days. Although this configuration can work, the effective lookback period isn’t the lowest value that meets the requirement. To avoid performance issues, set the values as follows: Period Type = Rolling Day Period = 3 This setting will have an effective lookback period of three days, which is the lowest value that meets the requirement.
Trigger an incident if there are three occurrences within seven days.	3	Rolling Day	7	The effective lookback period is seven rolling days. This is the lowest value that meets the requirement.
	3	Rolling Week	1
