Synopsis

Constructors

TrackCustomMetricProps()

Properties

DisableScaleIn

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

Metric

The custom CloudWatch metric to track.

PolicyName

A name for the scaling policy.

ScaleInCooldown

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

ScaleOutCooldown

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

TargetValue

The target value for the custom CloudWatch metric.

Constructors

TrackCustomMetricProps()

public TrackCustomMetricProps()

Properties

DisableScaleIn

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

public Nullable<bool> DisableScaleIn { get; set; }
Property Value

System.Nullable<System.Boolean>

Remarks

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

Metric

The custom CloudWatch metric to track.

public IMetric Metric { get; set; }
Property Value

IMetric

Remarks

The metric must represent utilization; that is, you will always get the following behavior:

    PolicyName

    A name for the scaling policy.

    public string PolicyName { get; set; }
    Property Value

    System.String

    Remarks

    Default: - Automatically generated name.

    ScaleInCooldown

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

    public Duration ScaleInCooldown { get; set; }
    Property Value

    Duration

    Remarks

    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

    ScaleOutCooldown

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

    public Duration ScaleOutCooldown { get; set; }
    Property Value

    Duration

    Remarks

    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

    TargetValue

    The target value for the custom CloudWatch metric.

    public double TargetValue { get; set; }
    Property Value

    System.Double
