type BasicStepScalingPolicyProps struct {
// Metric to scale on.
Metric awscloudwatch.IMetric `field:"required" json:"metric" yaml:"metric"`
// The intervals for scaling.
//
// Maps a range of metric values to a particular scaling behavior.
//
// Must be between 2 and 40 steps.
ScalingSteps *[]*ScalingInterval `field:"required" json:"scalingSteps" yaml:"scalingSteps"`
// How the adjustment numbers inside 'intervals' are interpreted.
// Default: ChangeInCapacity.
//
AdjustmentType AdjustmentType `field:"optional" json:"adjustmentType" yaml:"adjustmentType"`
// Grace period after scaling activity.
// Default: Default cooldown period on your AutoScalingGroup.
//
Cooldown awscdk.Duration `field:"optional" json:"cooldown" yaml:"cooldown"`
// Estimated time until a newly launched instance can send metrics to CloudWatch.
// Default: Same as the cooldown.
//
EstimatedInstanceWarmup awscdk.Duration `field:"optional" json:"estimatedInstanceWarmup" yaml:"estimatedInstanceWarmup"`
// How many evaluation periods of the metric to wait before triggering a scaling action.
//
// Raising this value can be used to smooth out the metric, at the expense
// of slower response times.
// Default: 1.
//
EvaluationPeriods *float64 `field:"optional" json:"evaluationPeriods" yaml:"evaluationPeriods"`
// Aggregation to apply to all data points over the evaluation periods.
//
// Only has meaning if `evaluationPeriods != 1`.
// Default: - The statistic from the metric if applicable (MIN, MAX, AVERAGE), otherwise AVERAGE.
//
MetricAggregationType MetricAggregationType `field:"optional" json:"metricAggregationType" yaml:"metricAggregationType"`
// Minimum absolute number to adjust capacity with as result of percentage scaling.
//
// Only when using AdjustmentType = PercentChangeInCapacity, this number controls
// the minimum absolute effect size.
// Default: No minimum scaling effect.
//
MinAdjustmentMagnitude *float64 `field:"optional" json:"minAdjustmentMagnitude" yaml:"minAdjustmentMagnitude"`
