@Generated("software.amazon.awssdk:codegen") public final class CustomizedScalingMetricSpecification extends Object implements SdkPojo, Serializable, ToCopyableBuilder<CustomizedScalingMetricSpecification.Builder,CustomizedScalingMetricSpecification>

Represents a CloudWatch metric of your choosing that can be used for dynamic scaling as part of a target tracking scaling policy.

To create your customized scaling metric specification:

  • Add values for each required parameter from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish Custom Metrics in the Amazon CloudWatch User Guide.

  • Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases.

For information about terminology, available metrics, or how to publish new metrics, see Amazon CloudWatch Concepts in the Amazon CloudWatch User Guide.

  • Method Details

    • metricName

      public final String metricName()

      The name of the metric.

      Returns:
      The name of the metric.

    • namespace

      public final String namespace()

      The namespace of the metric.

      Returns:
      The namespace of the metric.

    • hasDimensions

      public final boolean hasDimensions()
      For responses, this returns true if the service returned a value for the Dimensions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • dimensions

      public final List<MetricDimension> dimensions()

      The dimensions of the metric.

      Conditional: If you published your metric with dimensions, you must specify the same dimensions in your customized scaling metric specification.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasDimensions() method.

      Returns:
      The dimensions of the metric.

      Conditional: If you published your metric with dimensions, you must specify the same dimensions in your customized scaling metric specification.

    • statistic

      public final MetricStatistic statistic()

      The statistic of the metric.

      If the service returns an enum value that is not available in the current SDK version, statistic will return MetricStatistic.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from statisticAsString().

      Returns:
      The statistic of the metric.
      See Also:

    • statisticAsString

      public final String statisticAsString()

      The statistic of the metric.

      If the service returns an enum value that is not available in the current SDK version, statistic will return MetricStatistic.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from statisticAsString().

      Returns:
      The statistic of the metric.

    • unit

      public final String unit()

      The unit of the metric.

      Returns:
      The unit of the metric.

    • toBuilder

      public CustomizedScalingMetricSpecification.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<CustomizedScalingMetricSpecification.Builder,CustomizedScalingMetricSpecification>
      Returns:
      a builder for type T

    • builder

      public static CustomizedScalingMetricSpecification.Builder builder()

    • serializableBuilderClass

      public static Class<? extends CustomizedScalingMetricSpecification.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
