Defined in:



When passing PredefinedMetricSpecification as input to an Aws::Client method, you can use a vanilla Hash:

  predefined_metric_type: "DynamoDBReadCapacityUtilization", # required, accepts DynamoDBReadCapacityUtilization, DynamoDBWriteCapacityUtilization, ALBRequestCountPerTarget, RDSReaderAverageCPUUtilization, RDSReaderAverageDatabaseConnections, EC2SpotFleetRequestAverageCPUUtilization, EC2SpotFleetRequestAverageNetworkIn, EC2SpotFleetRequestAverageNetworkOut, SageMakerVariantInvocationsPerInstance, ECSServiceAverageCPUUtilization, ECSServiceAverageMemoryUtilization
  resource_label: "ResourceLabel",

Represents a predefined metric for a target tracking scaling policy to use with Application Auto Scaling.

Instance Attribute Details


The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleet requests and ECS services.

Possible values:

  • DynamoDBReadCapacityUtilization
  • DynamoDBWriteCapacityUtilization
  • ALBRequestCountPerTarget
  • RDSReaderAverageCPUUtilization
  • RDSReaderAverageDatabaseConnections
  • EC2SpotFleetRequestAverageCPUUtilization
  • EC2SpotFleetRequestAverageNetworkIn
  • EC2SpotFleetRequestAverageNetworkOut
  • SageMakerVariantInvocationsPerInstance
  • ECSServiceAverageCPUUtilization
  • ECSServiceAverageMemoryUtilization


  • (String)

    The metric type.


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 attached to the Spot Fleet request or ECS service.

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.


  • (String)

    Identifies the resource associated with the metric type.
