EvaluationWindow

sealed class EvaluationWindow

The evaluation window that an alarm uses to select the range of metric data that it evaluates each time it runs. This is a union type. Set exactly one of its members, SlidingWindow or WallClockWindow. If you don't set EvaluationWindow, the alarm uses a SlidingWindow by default.

For more information, see Alarm evaluation windows in the CloudWatch User Guide.
