Synopsis

Properties

AdjustmentType	How the adjustment numbers inside 'intervals' are interpreted.
Cooldown	Grace period after scaling activity.
EstimatedInstanceWarmup	Estimated time until a newly launched instance can send metrics to CloudWatch.
EvaluationPeriods	How many evaluation periods of the metric to wait before triggering a scaling action.
Metric	Metric to scale on.
MetricAggregationType	Aggregation to apply to all data points over the evaluation periods.
MinAdjustmentMagnitude	Minimum absolute number to adjust capacity with as result of percentage scaling.
ScalingSteps	The intervals for scaling.

Properties

AdjustmentType

How the adjustment numbers inside 'intervals' are interpreted.

virtual Nullable<AdjustmentType> AdjustmentType { get; }

Property Value

System.Nullable<AdjustmentType>

Remarks

Default: ChangeInCapacity

Cooldown

Grace period after scaling activity.

virtual Duration Cooldown { get; }

Property Value

Duration

Remarks

Default: Default cooldown period on your AutoScalingGroup

EstimatedInstanceWarmup

Estimated time until a newly launched instance can send metrics to CloudWatch.

virtual Duration EstimatedInstanceWarmup { get; }

Property Value

Duration

Remarks

Default: Same as the cooldown

EvaluationPeriods

How many evaluation periods of the metric to wait before triggering a scaling action.

virtual Nullable<double> EvaluationPeriods { get; }

Property Value

System.Nullable<System.Double>

Remarks

Raising this value can be used to smooth out the metric, at the expense of slower response times.

Default: 1

Metric

Metric to scale on.

IMetric Metric { get; }

Property Value

IMetric

MetricAggregationType

Aggregation to apply to all data points over the evaluation periods.

virtual Nullable<MetricAggregationType> MetricAggregationType { get; }

Property Value

System.Nullable<MetricAggregationType>

Remarks

Only has meaning if evaluationPeriods != 1.

Default: - The statistic from the metric if applicable (MIN, MAX, AVERAGE), otherwise AVERAGE.

MinAdjustmentMagnitude

Minimum absolute number to adjust capacity with as result of percentage scaling.

virtual Nullable<double> MinAdjustmentMagnitude { get; }

Property Value

System.Nullable<System.Double>

Remarks

Only when using AdjustmentType = PercentChangeInCapacity, this number controls the minimum absolute effect size.

Default: No minimum scaling effect

ScalingSteps

The intervals for scaling.

IScalingInterval[] ScalingSteps { get; }

Property Value

IScalingInterval[]

Remarks

Maps a range of metric values to a particular scaling behavior.
