    • autoScalingGroupName

      @Stability(Stable) public CfnScalingPolicyProps.Builder autoScalingGroupName(String autoScalingGroupName)
      Parameters:
      autoScalingGroupName - The name of the Auto Scaling group. This parameter is required.
      Returns:
      this
    • adjustmentType

      @Stability(Stable) public CfnScalingPolicyProps.Builder adjustmentType(String adjustmentType)
      Parameters:
      adjustmentType - Specifies how the scaling adjustment is interpreted (for example, an absolute number or a percentage). The valid values are ChangeInCapacity , ExactCapacity , and PercentChangeInCapacity .

      Required if the policy type is StepScaling or SimpleScaling . For more information, see Scaling adjustment types in the Amazon EC2 Auto Scaling User Guide .

      Returns:
      this
    • cooldown

      @Stability(Stable) public CfnScalingPolicyProps.Builder cooldown(String cooldown)
      Parameters:
      cooldown - A cooldown period, in seconds, that applies to a specific simple scaling policy. When a cooldown period is specified here, it overrides the default cooldown.

      Valid only if the policy type is SimpleScaling . For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide .

      Default: None

      Returns:
      this
    • estimatedInstanceWarmup

      @Stability(Stable) public CfnScalingPolicyProps.Builder estimatedInstanceWarmup(Number estimatedInstanceWarmup)
      Parameters:
      estimatedInstanceWarmup - Not needed if the default instance warmup is defined for the group.. The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This warm-up period applies to instances launched due to a specific target tracking or step scaling policy. When a warm-up period is specified here, it overrides the default instance warmup.

      Valid only if the policy type is TargetTrackingScaling or StepScaling .

      The default is to use the value for the default instance warmup defined for the group. If default instance warmup is null, then EstimatedInstanceWarmup falls back to the value of default cooldown.

      Returns:
      this
    • metricAggregationType

      @Stability(Stable) public CfnScalingPolicyProps.Builder metricAggregationType(String metricAggregationType)
      Parameters:
      metricAggregationType - The aggregation type for the CloudWatch metrics. The valid values are Minimum , Maximum , and Average . If the aggregation type is null, the value is treated as Average .

      Valid only if the policy type is StepScaling .

      Returns:
      this
    • minAdjustmentMagnitude

      @Stability(Stable) public CfnScalingPolicyProps.Builder minAdjustmentMagnitude(Number minAdjustmentMagnitude)
      Parameters:
      minAdjustmentMagnitude - The minimum value to scale by when the adjustment type is PercentChangeInCapacity . For example, suppose that you create a step scaling policy to scale out an Auto Scaling group by 25 percent and you specify a MinAdjustmentMagnitude of 2. If the group has 4 instances and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Amazon EC2 Auto Scaling scales out the group by 2 instances.

      Valid only if the policy type is StepScaling or SimpleScaling . For more information, see Scaling adjustment types in the Amazon EC2 Auto Scaling User Guide .

      Some Auto Scaling groups use instance weights. In this case, set the MinAdjustmentMagnitude to a value that is at least as large as your largest instance weight.

      Returns:
      this
    • policyType

      @Stability(Stable) public CfnScalingPolicyProps.Builder policyType(String policyType)
      Parameters:
      policyType - One of the following policy types:.
      • TargetTrackingScaling
      • StepScaling
      • SimpleScaling (default)
      • PredictiveScaling
      Returns:

      Required if the policy type is PredictiveScaling .

      Returns:
      this
    • predictiveScalingConfiguration

      @Stability(Stable) public CfnScalingPolicyProps.Builder predictiveScalingConfiguration(CfnScalingPolicy.PredictiveScalingConfigurationProperty predictiveScalingConfiguration)

    • scalingAdjustment

      @Stability(Stable) public CfnScalingPolicyProps.Builder scalingAdjustment(Number scalingAdjustment)
      Parameters:
      scalingAdjustment - The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity. For exact capacity, you must specify a non-negative value.
