public static interface CfnScalingPolicy.PredictiveScalingMetricSpecificationProperty

A structure that specifies a metric specification for the `MetricSpecifications` property of the [AWS::AutoScaling::ScalingPolicy PredictiveScalingConfiguration](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-autoscaling-scalingpolicy-predictivescalingconfiguration.html) property type.

For more information, see Predictive scaling in the Amazon EC2 Auto Scaling User Guide .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.

         .targetValue(123)

default java.lang.Object	getPredefinedLoadMetricSpecification() The load metric specification.
default java.lang.Object	getPredefinedMetricPairSpecification() The metric pair specification from which Amazon EC2 Auto Scaling determines the appropriate scaling metric and load metric to use.
default java.lang.Object	getPredefinedScalingMetricSpecification() The scaling metric specification.
java.lang.Number	getTargetValue() Specifies the target utilization.

Method Detail

getTargetValue

java.lang.Number getTargetValue()

Specifies the target utilization.

Some metrics are based on a count instead of a percentage, such as the request count for an Application Load Balancer or the number of messages in an SQS queue. If the scaling policy specifies one of these metrics, specify the target utilization as the optimal average request or message count per instance during any one-minute interval.

getPredefinedLoadMetricSpecification

default java.lang.Object getPredefinedLoadMetricSpecification()

The load metric specification.

If you specify PredefinedMetricPairSpecification , don't specify this property.

getPredefinedMetricPairSpecification

default java.lang.Object getPredefinedMetricPairSpecification()

The metric pair specification from which Amazon EC2 Auto Scaling determines the appropriate scaling metric and load metric to use.

With predictive scaling, you must specify either a metric pair, or a load metric and a scaling metric individually. Specifying a metric pair instead of individual metrics provides a simpler way to configure metrics for a scaling policy. You choose the metric pair, and the policy automatically knows the correct sum and average statistics to use for the load metric and the scaling metric.

getPredefinedScalingMetricSpecification

default java.lang.Object getPredefinedScalingMetricSpecification()

The scaling metric specification.

If you specify PredefinedMetricPairSpecification , don't specify this property.

builder

static CfnScalingPolicy.PredictiveScalingMetricSpecificationProperty.Builder builder()

Returns:

a CfnScalingPolicy.PredictiveScalingMetricSpecificationProperty.Builder of CfnScalingPolicy.PredictiveScalingMetricSpecificationProperty
