Temporarily turn off scaling policies

After you configure auto scaling, you have the following options if you need to investigate an issue without interference from scaling policies (dynamic scaling):

  • Temporarily suspend and then resume scaling activities by calling the register-scalable-target CLI command or RegisterScalableTarget API action, specifying a Boolean value for both DynamicScalingInSuspended and DynamicScalingOutSuspended.

    The following example shows how to suspend scaling policies for a variant named my-variant, running on the my-endpoint endpoint.

    aws application-autoscaling register-scalable-target \
  --service-namespace sagemaker \
  --resource-id endpoint/my-endpoint/variant/my-variant \
  --scalable-dimension sagemaker:variant:DesiredInstanceCount \
  --suspended-state '{"DynamicScalingInSuspended":true,"DynamicScalingOutSuspended":true}'

  • Prevent specific target tracking scaling policies from scaling in your variant by disabling the policy's scale-in portion. This method prevents the scaling policy from deleting instances, while still allowing it to create them as needed.

    Temporarily disable and then enable scale-in activities by editing the policy using the put-scaling-policy CLI command or the PutScalingPolicy API action, specifying a Boolean value for DisableScaleIn.

    The following is an example of a target tracking configuration for a scaling policy that will scale out but not scale in. 

    {
    "TargetValue": 70.0,
    "PredefinedMetricSpecification":
    {
        "PredefinedMetricType": "SageMakerVariantInvocationsPerInstance"
    },
    "DisableScaleIn": true
}
