class Aws::AutoScalingPlans::Types::PredefinedScalingMetricSpecification

Represents a predefined metric that can be used for dynamic scaling as part of a target tracking scaling policy.

@note When making an API call, you may pass PredefinedScalingMetricSpecification

data as a hash:

    {
      predefined_scaling_metric_type: "ASGAverageCPUUtilization", # required, accepts ASGAverageCPUUtilization, ASGAverageNetworkIn, ASGAverageNetworkOut, DynamoDBReadCapacityUtilization, DynamoDBWriteCapacityUtilization, ECSServiceAverageCPUUtilization, ECSServiceAverageMemoryUtilization, ALBRequestCountPerTarget, RDSReaderAverageCPUUtilization, RDSReaderAverageDatabaseConnections, EC2SpotFleetRequestAverageCPUUtilization, EC2SpotFleetRequestAverageNetworkIn, EC2SpotFleetRequestAverageNetworkOut
      resource_label: "ResourceLabel",
    }

@!attribute [rw] predefined_scaling_metric_type

The metric type. The `ALBRequestCountPerTarget` metric type applies
only to Auto Scaling groups, Spot Fleet requests, and ECS services.
@return [String]

@!attribute [rw] resource_label

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.

You create the resource label by appending the final portion of the
load balancer ARN and the final portion of the target group ARN into
a single value, separated by a forward slash (/). 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.

This is an example:
app/EC2Co-EcsEl-1TKLTMITMM0EO/f37c06a68c1748aa/targetgroup/EC2Co-Defau-LDNM7Q3ZH1ZN/6d4ea56ca2d6a18d.

To find the ARN for an Application Load Balancer, use the
[DescribeLoadBalancers][1] API operation. To find the ARN for the
target group, use the [DescribeTargetGroups][2] API operation.
