ExampleMetadata: infused

Properties

AdjustmentType

How the adjustment numbers inside 'intervals' are interpreted.

AdjustmentType? AdjustmentType { get; }

Property Value

AdjustmentType?

Remarks

Default: ChangeInCapacity

Cooldown

Grace period after scaling activity.

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.

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.

double? EvaluationPeriods { get; }

Property Value

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.

MetricAggregationType? MetricAggregationType { get; }

Property Value

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.

double? MinAdjustmentMagnitude { get; }

Property Value

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.
