AWS::AutoScalingPlans::ScalingPlan PredefinedLoadMetricSpecification

PredefinedLoadMetricSpecification is a subproperty of ScalingInstruction that specifies a predefined load metric for predictive scaling to use with AWS Auto Scaling.

After creating your scaling plan, you can use the AWS Auto Scaling console to visualize forecasts for the specified metric. For more information, see View Scaling Information for a Resource in the AWS Auto Scaling User Guide.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "PredefinedLoadMetricType" : String, "ResourceLabel" : String }



The metric type.

Required: Yes

Type: String

Allowed values: ALBTargetGroupRequestCount | ASGTotalCPUUtilization | ASGTotalNetworkIn | ASGTotalNetworkOut

Update requires: No interruption


Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBTargetGroupRequestCount and there is a target group for an Application Load Balancer attached to the Auto Scaling group.

Elastic Load Balancing sends data about your load balancers to Amazon CloudWatch. CloudWatch collects the data and specifies the format to use to access the data. The format is app/<load-balancer-name>/<load-balancer-id>/targetgroup/<target-group-name>/<target-group-id>, where:

  • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN.

  • targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

Required: Conditional

Type: String

Minimum: 1

Maximum: 1023
