StepScalingPolicy

class aws_cdk.aws_applicationautoscaling.StepScalingPolicy(scope, id, *, scaling_target, metric, scaling_steps, adjustment_type=None, cooldown=None, min_adjustment_magnitude=None)

Bases: aws_cdk.core.Construct

Define a acaling strategy which scales depending on absolute values of some metric.

You can specify the scaling behavior for various values of the metric.

Implemented using one or more CloudWatch alarms and Step Scaling Policies.

__init__(scope, id, *, scaling_target, metric, scaling_steps, adjustment_type=None, cooldown=None, min_adjustment_magnitude=None)
Parameters
  • scope (Construct) –

  • id (str) –

  • props

  • scaling_target (IScalableTarget) – The scaling target.

  • metric (IMetric) – Metric to scale on.

  • scaling_steps (List[ScalingInterval]) – The intervals for scaling. Maps a range of metric values to a particular scaling behavior.

  • adjustment_type (Optional[AdjustmentType]) – How the adjustment numbers inside ‘intervals’ are interpreted. Default: ChangeInCapacity

  • cooldown (Optional[Duration]) – Grace period after scaling activity. Subsequent scale outs during the cooldown period are squashed so that only the biggest scale out happens. Subsequent scale ins during the cooldown period are ignored. Default: No cooldown period

  • min_adjustment_magnitude (Union[int, float, None]) – 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
