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

- PredefinedScalingMetricType

The metric type. The
ALBRequestCountPerTargetmetric type applies only to Auto Scaling groups, Spot Fleet requests, and ECS services.Type: String
Valid Values:
ASGAverageCPUUtilization | ASGAverageNetworkIn | ASGAverageNetworkOut | DynamoDBReadCapacityUtilization | DynamoDBWriteCapacityUtilization | ECSServiceAverageCPUUtilization | ECSServiceAverageMemoryUtilization | ALBRequestCountPerTarget | RDSReaderAverageCPUUtilization | RDSReaderAverageDatabaseConnections | EC2SpotFleetRequestAverageCPUUtilization | EC2SpotFleetRequestAverageNetworkIn | EC2SpotFleetRequestAverageNetworkOutRequired: Yes
- ResourceLabel
-
Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is
ALBRequestCountPerTargetand 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 API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.
