Class CfnScalingPolicy.StepAdjustmentProperty
StepAdjustment
specifies a step adjustment for the StepAdjustments
property of the AWS::AutoScaling::ScalingPolicy resource.
Inheritance

Implements CfnScalingPolicy.IStepAdjustmentProperty
Remarks
For the following examples, suppose that you have an alarm with a breach threshold of 50:
There are a few rules for the step adjustments for your step policy:
For more information, see Step adjustments in the Amazon EC2 Auto Scaling User Guide .
You can find a sample template snippet in the Examples section of the AWS::AutoScaling::ScalingPolicy
resource.

// The values are placeholders you should change.
using Amazon.CDK.AWS.AutoScaling;

Synopsis
Constructors
StepAdjustmentProperty() |
Properties
MetricIntervalLowerBound | The lower bound for the difference between the alarm threshold and the CloudWatch metric. |
MetricIntervalUpperBound | The upper bound for the difference between the alarm threshold and the CloudWatch metric. |
ScalingAdjustment | The amount by which to scale, based on the specified adjustment type. |
Constructors
StepAdjustmentProperty()
public StepAdjustmentProperty()
Properties
MetricIntervalLowerBound
The lower bound for the difference between the alarm threshold and the CloudWatch metric.
public Nullable<double> MetricIntervalLowerBound { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
If the metric value is above the breach threshold, the lower bound is inclusive (the metric must be greater than or equal to the threshold plus the lower bound). Otherwise, it is exclusive (the metric must be greater than the threshold plus the lower bound). A null value indicates negative infinity.
MetricIntervalUpperBound
The upper bound for the difference between the alarm threshold and the CloudWatch metric.
public Nullable<double> MetricIntervalUpperBound { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
If the metric value is above the breach threshold, the upper bound is exclusive (the metric must be less than the threshold plus the upper bound). Otherwise, it is inclusive (the metric must be less than or equal to the threshold plus the upper bound). A null value indicates positive infinity.
The upper bound must be greater than the lower bound.
ScalingAdjustment
The amount by which to scale, based on the specified adjustment type.
public double ScalingAdjustment { get; set; }
Property Value
System.Double
Remarks
A positive value adds to the current capacity while a negative number removes from the current capacity. For exact capacity, you must specify a non-negative value.
