public class CfnScalingPolicy
extends CfnResource
implements IInspectable

A CloudFormation AWS::AutoScaling::ScalingPolicy.

The AWS::AutoScaling::ScalingPolicy resource specifies an Amazon EC2 Auto Scaling scaling policy so that the Auto Scaling group can scale the number of instances available for your application.

For more information about using scaling policies to scale your Auto Scaling group automatically, see Dynamic scaling and 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.
 import software.amazon.awscdk.services.autoscaling.*;
 CfnScalingPolicy cfnScalingPolicy = CfnScalingPolicy.Builder.create(this, "MyCfnScalingPolicy")

Default: None

setCooldown

A cooldown period, in seconds, that applies to a specific simple scaling policy.

getEstimatedInstanceWarmup

@Stability(Stable)
@Nullable

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.

setEstimatedInstanceWarmup

@Stability(Stable)
public void setEstimatedInstanceWarmup(@Nullable
 Number value)

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.

getMetricAggregationType

Valid only if the policy type is StepScaling .

setMetricAggregationType

@Stability(Stable)
public void setMetricAggregationType(@Nullable
 String value)

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 .

getMinAdjustmentMagnitude

@Stability(Stable)
@Nullable
public Number getMinAdjustmentMagnitude()

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.

setMinAdjustmentMagnitude

@Stability(Stable)
public void setMinAdjustmentMagnitude(@Nullable

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.
