Class EvaluationWindow

java.lang.Object
software.amazon.awssdk.services.cloudwatch.model.EvaluationWindow
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<EvaluationWindow.Builder,EvaluationWindow>
@Generated("software.amazon.awssdk:codegen") public final class EvaluationWindow extends Object implements SdkPojo, Serializable, ToCopyableBuilder<EvaluationWindow.Builder,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.

  • Method Details

    • wallClockWindow

      public final WallClockWindow wallClockWindow()

      A wall clock window, which aligns the evaluated range to fixed clock boundaries that match the alarm's period, such as the top of the hour, midnight, or the start of the calendar week.

      Returns:
      A wall clock window, which aligns the evaluated range to fixed clock boundaries that match the alarm's period, such as the top of the hour, midnight, or the start of the calendar week.

    • slidingWindow

      public final SlidingWindow slidingWindow()

      A sliding window, which advances each time the alarm is evaluated, forming a rolling time window. This is the default evaluation window.

      Returns:
      A sliding window, which advances each time the alarm is evaluated, forming a rolling time window. This is the default evaluation window.

    • fromWallClockWindow

      public static EvaluationWindow fromWallClockWindow(WallClockWindow wallClockWindow)
      Create an instance of this class with wallClockWindow() initialized to the given value.

      A wall clock window, which aligns the evaluated range to fixed clock boundaries that match the alarm's period, such as the top of the hour, midnight, or the start of the calendar week.

      Create an instance of this class with slidingWindow() initialized to the given value.

      A sliding window, which advances each time the alarm is evaluated, forming a rolling time window. This is the default evaluation window.

      Parameters:

    • fromSlidingWindow

      public static EvaluationWindow fromSlidingWindow(Consumer<SlidingWindow.Builder> slidingWindow)
      Create an instance of this class with slidingWindow() initialized to the given value.

      A sliding window, which advances each time the alarm is evaluated, forming a rolling time window. This is the default evaluation window.

      Parameters:

    • type

      public EvaluationWindow.Type type()
      Retrieve an enum value representing which member of this object is populated. When this class is returned in a service response, this will be EvaluationWindow.Type.UNKNOWN_TO_SDK_VERSION if the service returned a member that is only known to a newer SDK version. When this class is created directly in your code, this will be EvaluationWindow.Type.UNKNOWN_TO_SDK_VERSION if zero members are set, and null if more than one member is set.
