            • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN

        • DisableScaleIn (boolean) --

          Indicates whether scale in by the target tracking policy is disabled. If the value is true , scale in is disabled and the target tracking policy won't remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false .

        • ScaleOutCooldown (integer) --

          The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. This value is not used if the scalable resource is an Auto Scaling group.

          While the cooldown period is in effect, the capacity that has been added by the previous scale out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. The intention is to continuously (but not excessively) scale out.

        • ScaleInCooldown (integer) --

          The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. This value is not used if the scalable resource is an Auto Scaling group.

          The cooldown period is used to block subsequent scale in requests until it has expired. The intention is to scale in conservatively to protect your application's availability. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, AWS Auto Scaling scales out your scalable target immediately.

        • EstimatedInstanceWarmup (integer) --

          The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This value is used only if the resource is an Auto Scaling group.

type ScalingPlanVersion

{'ApplicationSource': {'TagFilters': [{'Key': 'string', 'Values': ['string']}]}}

Creates a scaling plan.

A scaling plan contains a set of instructions used to configure dynamic scaling for the scalable resources in your application. AWS Auto Scaling creates target tracking scaling policies based on the scaling instructions in your scaling plan.

                • DisableScaleIn (boolean) --

                  Indicates whether scale in by the target tracking policy is disabled. If the value is true , scale in is disabled and the target tracking policy won't remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false .

                • ScaleOutCooldown (integer) --

                  The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. This value is not used if the scalable resource is an Auto Scaling group.

                  While the cooldown period is in effect, the capacity that has been added by the previous scale out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. The intention is to continuously (but not excessively) scale out.

                • ScaleInCooldown (integer) --

                  The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. This value is not used if the scalable resource is an Auto Scaling group.

                  The cooldown period is used to block subsequent scale in requests until it has expired. The intention is to scale in conservatively to protect your application's availability. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, AWS Auto Scaling scales out your scalable target immediately.

                • EstimatedInstanceWarmup (integer) --

                  The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This value is used only if the resource is an Auto Scaling group.

        • StatusCode (string) --

          The status of the scaling plan.

          • Active - The scaling plan is active.

          • ActiveWithProblems - The scaling plan is active, but the scaling configuration for one or more resources could not be applied.

          • CreationInProgress - The scaling plan is being created.

          • CreationFailed - The scaling plan could not be created.

          • DeletionInProgress - The scaling plan is being deleted.

          • DeletionFailed - The scaling plan could not be deleted.

        • StatusMessage (string) --

          A simple message about the current status of the scaling plan.

        • StatusStartTime (datetime) --

          The Unix timestamp when the scaling plan entered the current status.

        • CreationTime (datetime) --

          The Unix timestamp when the scaling plan was created.

    • NextToken (string) --

      The token required to get the next set of results. This value is null if there are no more results to return.
