GetScalingPlanResourceForecastData - Amazon Auto Scaling
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


Retrieves the forecast data for a scalable resource.

Capacity forecasts are represented as predicted values, or data points, that are calculated using historical data points from a specified CloudWatch load metric. Data points are available for up to 56 days.

Request Syntax

{ "EndTime": number, "ForecastDataType": "string", "ResourceId": "string", "ScalableDimension": "string", "ScalingPlanName": "string", "ScalingPlanVersion": number, "ServiceNamespace": "string", "StartTime": number }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


The exclusive end time of the time range for the forecast data to get. The maximum time duration between the start and end time is seven days.

Although this parameter can accept a date and time that is more than two days in the future, the availability of forecast data has limits. Amazon Auto Scaling only issues forecasts for periods of two days in advance.

Type: Timestamp

Required: Yes


The type of forecast data to get.

  • LoadForecast: The load metric forecast.

  • CapacityForecast: The capacity forecast.

  • ScheduledActionMinCapacity: The minimum capacity for each scheduled scaling action. This data is calculated as the larger of two values: the capacity forecast or the minimum capacity in the scaling instruction.

  • ScheduledActionMaxCapacity: The maximum capacity for each scheduled scaling action. The calculation used is determined by the predictive scaling maximum capacity behavior setting in the scaling instruction.

Type: String

Valid Values: CapacityForecast | LoadForecast | ScheduledActionMinCapacity | ScheduledActionMaxCapacity

Required: Yes


The ID of the resource. This string consists of a prefix (autoScalingGroup) followed by the name of a specified Auto Scaling group (my-asg). Example: autoScalingGroup/my-asg.

Type: String

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\r\n\t]*

Required: Yes


The scalable dimension for the resource. The only valid value is autoscaling:autoScalingGroup:DesiredCapacity.

Type: String

Valid Values: autoscaling:autoScalingGroup:DesiredCapacity

Required: Yes


The name of the scaling plan.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\p{Print}&&[^|:/]]+

Required: Yes


The version number of the scaling plan. Currently, the only valid value is 1.

Type: Long

Required: Yes


The namespace of the Amazon service. The only valid value is autoscaling.

Type: String

Valid Values: autoscaling

Required: Yes


The inclusive start time of the time range for the forecast data to get. The date and time can be at most 56 days before the current date and time.

Type: Timestamp

Required: Yes
