CpuUtilizationScalingProps

class aws_cdk.aws_ecs.CpuUtilizationScalingProps(*, disable_scale_in=None, policy_name=None, scale_in_cooldown=None, scale_out_cooldown=None, target_utilization_percent)

Bases: BaseTargetTrackingProps

The properties for enabling scaling based on CPU utilization.

Parameters:

disable_scale_in (Optional[bool]) – Indicates whether scale in by the target tracking policy is disabled. If the value is true, scale in is disabled and the target tracking policy won’t remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. Default: false
policy_name (Optional[str]) – A name for the scaling policy. Default: - Automatically generated name.
scale_in_cooldown (Optional[Duration]) – Period after a scale in activity completes before another scale in activity can start. Default: Duration.seconds(300) for the following scalable targets: ECS services, Spot Fleet requests, EMR clusters, AppStream 2.0 fleets, Aurora DB clusters, Amazon SageMaker endpoint variants, Custom resources. For all other scalable targets, the default value is Duration.seconds(0): DynamoDB tables, DynamoDB global secondary indexes, Amazon Comprehend document classification endpoints, Lambda provisioned concurrency
scale_out_cooldown (Optional[Duration]) – Period after a scale out activity completes before another scale out activity can start. Default: Duration.seconds(300) for the following scalable targets: ECS services, Spot Fleet requests, EMR clusters, AppStream 2.0 fleets, Aurora DB clusters, Amazon SageMaker endpoint variants, Custom resources. For all other scalable targets, the default value is Duration.seconds(0): DynamoDB tables, DynamoDB global secondary indexes, Amazon Comprehend document classification endpoints, Lambda provisioned concurrency
target_utilization_percent (Union[int, float]) – The target value for CPU utilization across all tasks in the service.

Example:

# target: elbv2.ApplicationTargetGroup
# service: ecs.BaseService

scaling = service.auto_scale_task_count(max_capacity=10)
scaling.scale_on_cpu_utilization("CpuScaling",
    target_utilization_percent=50
)

scaling.scale_on_request_count("RequestScaling",
    requests_per_target=10000,
    target_group=target
)

Attributes

disable_scale_in

Indicates whether scale in by the target tracking policy is disabled.

If the value is true, scale in is disabled and the target tracking policy won’t remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource.

Default:: false

policy_name

A name for the scaling policy.

Default:

Automatically generated name.

scale_in_cooldown

Period after a scale in activity completes before another scale in activity can start.

Default:

Duration.seconds(300) for the following scalable targets: ECS services, Spot Fleet requests, EMR clusters, AppStream 2.0 fleets, Aurora DB clusters, Amazon SageMaker endpoint variants, Custom resources. For all other scalable targets, the default value is Duration.seconds(0): DynamoDB tables, DynamoDB global secondary indexes, Amazon Comprehend document classification endpoints, Lambda provisioned concurrency

scale_out_cooldown

Period after a scale out activity completes before another scale out activity can start.

Default:

Duration.seconds(300) for the following scalable targets: ECS services, Spot Fleet requests, EMR clusters, AppStream 2.0 fleets, Aurora DB clusters, Amazon SageMaker endpoint variants, Custom resources. For all other scalable targets, the default value is Duration.seconds(0): DynamoDB tables, DynamoDB global secondary indexes, Amazon Comprehend document classification endpoints, Lambda provisioned concurrency

target_utilization_percent: The target value for CPU utilization across all tasks in the service.
