AWS::AutoScalingPlans::ScalingPlan PredefinedScalingMetricSpecification - AWS CloudFormation

AWS::AutoScalingPlans::ScalingPlan PredefinedScalingMetricSpecification

PredefinedScalingMetricSpecification is a subproperty of TargetTrackingConfiguration that specifies a customized scaling metric for a target tracking configuration to use with AWS Auto Scaling.

Syntax

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

JSON

{ "PredefinedScalingMetricType" : String, "ResourceLabel" : String }

Properties

PredefinedScalingMetricType

The metric type. The ALBRequestCountPerTarget metric type applies only to Auto Scaling groups, Spot Fleet requests, and ECS services.

Required: Yes

Type: String

Allowed values: ALBRequestCountPerTarget | ASGAverageCPUUtilization | ASGAverageNetworkIn | ASGAverageNetworkOut | DynamoDBReadCapacityUtilization | DynamoDBWriteCapacityUtilization | EC2SpotFleetRequestAverageCPUUtilization | EC2SpotFleetRequestAverageNetworkIn | EC2SpotFleetRequestAverageNetworkOut | ECSServiceAverageCPUUtilization | ECSServiceAverageMemoryUtilization | RDSReaderAverageCPUUtilization | RDSReaderAverageDatabaseConnections

Update requires: No interruption

ResourceLabel

Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group for an Application Load Balancer attached to the Auto Scaling group, Spot Fleet request, or ECS service.

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
