Defined in:



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

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

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

Instance Attribute Details


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

Possible values:

  • ASGAverageCPUUtilization
  • ASGAverageNetworkIn
  • ASGAverageNetworkOut
  • DynamoDBReadCapacityUtilization
  • DynamoDBWriteCapacityUtilization
  • ECSServiceAverageCPUUtilization
  • ECSServiceAverageMemoryUtilization
  • ALBRequestCountPerTarget
  • RDSReaderAverageCPUUtilization
  • RDSReaderAverageDatabaseConnections
  • EC2SpotFleetRequestAverageCPUUtilization
  • EC2SpotFleetRequestAverageNetworkIn
  • EC2SpotFleetRequestAverageNetworkOut


  • (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 for an Application Load Balancer attached to the Auto Scaling group, 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.
