Overview

Note:

EvaluationWindow is a union - when making an API calls you must set exactly one of the members.

Note:

EvaluationWindow is a union - when returned from an API call exactly one value will be set and the returned type will be a subclass of EvaluationWindow corresponding to the set member.

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.
