Put Scaling Policy
autoscaling_put_scaling_policy | R Documentation |
Creates or updates a scaling policy for an Auto Scaling group¶
Description¶
Creates or updates a scaling policy for an Auto Scaling group. Scaling policies are used to scale an Auto Scaling group based on configurable metrics. If no policies are defined, the dynamic scaling and predictive scaling features are not used.
For more information about using dynamic scaling, see Target tracking scaling policies and Step and simple scaling policies in the Amazon EC2 Auto Scaling User Guide.
For more information about using predictive scaling, see Predictive scaling for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
You can view the scaling policies for an Auto Scaling group using the
describe_policies
API call. If you are no longer using a scaling
policy, you can delete it by calling the delete_policy
API.
Usage¶
autoscaling_put_scaling_policy(AutoScalingGroupName, PolicyName,
PolicyType, AdjustmentType, MinAdjustmentStep, MinAdjustmentMagnitude,
ScalingAdjustment, Cooldown, MetricAggregationType, StepAdjustments,
EstimatedInstanceWarmup, TargetTrackingConfiguration, Enabled,
PredictiveScalingConfiguration)
Arguments¶
AutoScalingGroupName |
[required] The name of the Auto Scaling group. |
PolicyName |
[required] The name of the policy. |
PolicyType |
One of the following policy types:
|
AdjustmentType |
Specifies how the scaling adjustment is interpreted (for example,
an absolute number or a percentage). The valid values are
Required if the policy type is |
MinAdjustmentStep |
Available for backward compatibility. Use
|
MinAdjustmentMagnitude |
The minimum value to scale by when the adjustment type is
Valid only if the policy type is Some Auto Scaling groups use instance weights. In this case, set the
|
ScalingAdjustment |
The amount by which to scale, based on the specified adjustment type. 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. Required if the policy type is |
Cooldown |
A cooldown period, in seconds, that applies to a specific simple scaling policy. When a cooldown period is specified here, it overrides the default cooldown. Valid only if the policy type is Default: None |
MetricAggregationType |
The aggregation type for the CloudWatch metrics. The valid values
are Valid only if the policy type is |
StepAdjustments |
A set of adjustments that enable you to scale based on the size of the alarm breach. Required if the policy type is |
EstimatedInstanceWarmup |
Not needed if the default instance warmup is defined for the group. The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This warm-up period applies to instances launched due to a specific target tracking or step scaling policy. When a warm-up period is specified here, it overrides the default instance warmup. Valid only if the policy type is The default is to use the value for the default instance warmup
defined for the group. If default instance warmup is null, then
|
TargetTrackingConfiguration |
A target tracking scaling policy. Provides support for predefined or custom metrics. The following predefined metrics are available:
If you specify For more information, see TargetTrackingConfiguration in the Amazon EC2 Auto Scaling API Reference. Required if the policy type is
|
Enabled |
Indicates whether the scaling policy is enabled or disabled. The default is enabled. For more information, see Disable a scaling policy for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide. |
PredictiveScalingConfiguration |
A predictive scaling policy. Provides support for predefined and custom metrics. Predefined metrics include CPU utilization, network in/out, and the Application Load Balancer request count. For more information, see PredictiveScalingConfiguration in the Amazon EC2 Auto Scaling API Reference. Required if the policy type is
