The metric type. The
ALBRequestCountPerTarget
metric type applies only to Spot Fleets and ECS services.Type: String
Valid Values:
DynamoDBReadCapacityUtilization | DynamoDBWriteCapacityUtilization | ALBRequestCountPerTarget | RDSReaderAverageCPUUtilization | RDSReaderAverageDatabaseConnections | EC2SpotFleetRequestAverageCPUUtilization | EC2SpotFleetRequestAverageNetworkIn | EC2SpotFleetRequestAverageNetworkOut | SageMakerVariantInvocationsPerInstance | ECSServiceAverageCPUUtilization | ECSServiceAverageMemoryUtilization | AppStreamAverageCapacityUtilization | ComprehendInferenceUtilization | LambdaProvisionedConcurrencyUtilization | CassandraReadCapacityUtilization | CassandraWriteCapacityUtilization | KafkaBrokerStorageUtilization | ElastiCachePrimaryEngineCPUUtilization | ElastiCacheReplicaEngineCPUUtilization | ElastiCacheDatabaseMemoryUsageCountedForEvictPercentage | NeptuneReaderAverageCPUUtilization | SageMakerVariantProvisionedConcurrencyUtilization | ElastiCacheDatabaseCapacityUsageCountedForEvictPercentage | SageMakerInferenceComponentInvocationsPerCopy | WorkSpacesAverageUserSessionsCapacityUtilization | SageMakerInferenceComponentConcurrentRequestsPerCopyHighResolution | SageMakerVariantConcurrentRequestsPerModelHighResolution
Required: Yes
- ResourceLabel
-
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 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 of the resource label is:
app/my-alb/778d41231b141a0f/targetgroup/my-alb-target-group/943f017f100becff
.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.
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.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1023.
