Overview

Note:

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, AppStreamAverageCapacityUtilization, ComprehendInferenceUtilization, LambdaProvisionedConcurrencyUtilization, CassandraReadCapacityUtilization, CassandraWriteCapacityUtilization
  resource_label: "ResourceLabel",
}

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

Only the AWS services that you're using send metrics to Amazon CloudWatch. To determine whether a desired metric already exists by looking up its namespace and dimension using the CloudWatch metrics dashboard in the console, follow the procedure in Building Dashboards with CloudWatch in the Application Auto Scaling User Guide.

Instance Attribute Details

#predefined_metric_typeString

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
  • AppStreamAverageCapacityUtilization
  • ComprehendInferenceUtilization
  • LambdaProvisionedConcurrencyUtilization
  • CassandraReadCapacityUtilization
  • CassandraWriteCapacityUtilization

Returns:

  • (String)

    The metric type.

#resource_labelString

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.

Returns:

  • (String)

    Identifies the resource associated with the metric type.
