Types

type Alarm 

type Alarm struct {

	// The Amazon Resource Name (ARN) of the alarm.
	//
	// AlarmARN is a required field
	AlarmARN *string `type:"string" required:"true"`

	// The name of the alarm.
	//
	// AlarmName is a required field
	AlarmName *string `type:"string" required:"true"`
	// contains filtered or unexported fields
}

An object representing a CloudWatch alarm associated with a scaling policy.

func (Alarm) GoString 

func (s Alarm) GoString() string

GoString returns the string representation

func (Alarm) String 

func (s Alarm) String() string

String returns the string representation

type ApplicationAutoScaling 

type ApplicationAutoScaling struct {
	*client.Client
}

Application Auto Scaling is a general purpose Auto Scaling service for supported elastic AWS resources. With Application Auto Scaling, you can automatically scale your AWS resources, with an experience similar to that of Auto Scaling.

Application Auto Scaling supports scaling the following AWS resources:

  • Amazon ECS services

  • Amazon EC2 Spot fleet instances

You can use Application Auto Scaling to accomplish the following tasks:

  • Define scaling policies for automatically adjusting your AWS resources

  • Scale your resources in response to CloudWatch alarms

  • View history of your scaling events

Application Auto Scaling is available in the following regions:

  • us-east-1

  • us-west-1

  • us-west-2

  • ap-southeast-1

  • ap-southeast-2

  • ap-northeast-1

  • eu-central-1

  • eu-west-1

The service client's operations are safe to be used concurrently. It is not safe to mutate any of the client's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *ApplicationAutoScaling

New creates a new instance of the ApplicationAutoScaling client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a ApplicationAutoScaling client from just a session.
svc := applicationautoscaling.New(mySession)

// Create a ApplicationAutoScaling client with additional configuration
svc := applicationautoscaling.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*ApplicationAutoScaling) DeleteScalingPolicy 

func (c *ApplicationAutoScaling) DeleteScalingPolicy(input *DeleteScalingPolicyInput) (*DeleteScalingPolicyOutput, error)

DeleteScalingPolicy API operation for Application Auto Scaling.

Deletes an Application Auto Scaling scaling policy that was previously created. If you are no longer using a scaling policy, you can delete it with this operation.

Deleting a policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action.

To create a new scaling policy or update an existing one, see PutScalingPolicy.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Application Auto Scaling's API operation DeleteScalingPolicy for usage and error information.

Returned Error Codes:

  • ValidationException An exception was thrown for a validation issue. Review the available parameters for the API request.

  • ObjectNotFoundException The specified object could not be found. For any Put or Register API operation, which depends on the existence of a scalable target, this exception is thrown if the scalable target with the specified service namespace, resource ID, and scalable dimension does not exist. For any Delete or Deregister API operation, this exception is thrown if the resource that is to be deleted or deregistered cannot be found.

  • ConcurrentUpdateException Concurrent updates caused an exception, for example, if you request an update to an Application Auto Scaling resource that already has a pending update.

  • InternalServiceException The service encountered an internal error.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/applicationautoscaling"
)

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := applicationautoscaling.New(sess)

	params := &applicationautoscaling.DeleteScalingPolicyInput{
		PolicyName:        aws.String("ResourceIdMaxLen1600"), // Required
		ResourceId:        aws.String("ResourceIdMaxLen1600"), // Required
		ScalableDimension: aws.String("ScalableDimension"),    // Required
		ServiceNamespace:  aws.String("ServiceNamespace"),     // Required
	}
	resp, err := svc.DeleteScalingPolicy(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*ApplicationAutoScaling) DeleteScalingPolicyRequest 

func (c *ApplicationAutoScaling) DeleteScalingPolicyRequest(input *DeleteScalingPolicyInput) (req *request.Request, output *DeleteScalingPolicyOutput)

DeleteScalingPolicyRequest generates a "aws/request.Request" representing the client's request for the DeleteScalingPolicy operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

See DeleteScalingPolicy for usage and error information.

Creating a request object using this method should be used when you want to inject custom logic into the request's lifecycle using a custom handler, or if you want to access properties on the request object before or after sending the request. If you just want the service response, call the DeleteScalingPolicy method directly instead.

Note: You must call the "Send" method on the returned request object in order to execute the request. 

// Example sending a request using the DeleteScalingPolicyRequest method.
req, resp := client.DeleteScalingPolicyRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*ApplicationAutoScaling) DeregisterScalableTarget 

func (c *ApplicationAutoScaling) DeregisterScalableTarget(input *DeregisterScalableTargetInput) (*DeregisterScalableTargetOutput, error)

DeregisterScalableTarget API operation for Application Auto Scaling.

Deregisters a scalable target that was previously registered. If you are no longer using a scalable target, you can delete it with this operation. When you deregister a scalable target, all of the scaling policies that are associated with that scalable target are deleted.

To create a new scalable target or update an existing one, see RegisterScalableTarget.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Application Auto Scaling's API operation DeregisterScalableTarget for usage and error information.

Returned Error Codes:

  • ValidationException An exception was thrown for a validation issue. Review the available parameters for the API request.

  • ObjectNotFoundException The specified object could not be found. For any Put or Register API operation, which depends on the existence of a scalable target, this exception is thrown if the scalable target with the specified service namespace, resource ID, and scalable dimension does not exist. For any Delete or Deregister API operation, this exception is thrown if the resource that is to be deleted or deregistered cannot be found.

  • ConcurrentUpdateException Concurrent updates caused an exception, for example, if you request an update to an Application Auto Scaling resource that already has a pending update.

  • InternalServiceException The service encountered an internal error.

PutScalingPolicyRequest generates a "aws/request.Request" representing the client's request for the PutScalingPolicy operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

See PutScalingPolicy for usage and error information.

Creating a request object using this method should be used when you want to inject custom logic into the request's lifecycle using a custom handler, or if you want to access properties on the request object before or after sending the request. If you just want the service response, call the PutScalingPolicy method directly instead.

Note: You must call the "Send" method on the returned request object in order to execute the request. 

// Example sending a request using the PutScalingPolicyRequest method.
req, resp := client.PutScalingPolicyRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*ApplicationAutoScaling) RegisterScalableTarget 

func (c *ApplicationAutoScaling) RegisterScalableTarget(input *RegisterScalableTargetInput) (*RegisterScalableTargetOutput, error)

RegisterScalableTarget API operation for Application Auto Scaling.

Registers or updates a scalable target. A scalable target is a resource that can be scaled out or in with Application Auto Scaling. After you have registered a scalable target, you can use this operation to update the minimum and maximum values for your scalable dimension.

After you register a scalable target with Application Auto Scaling, you can create and apply scaling policies to it with PutScalingPolicy. You can view the existing scaling policies for a service namespace with DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it with DeregisterScalableTarget.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Application Auto Scaling's API operation RegisterScalableTarget for usage and error information.

Returned Error Codes:

  • ValidationException An exception was thrown for a validation issue. Review the available parameters for the API request.

  • LimitExceededException Your account exceeded a limit. This exception is thrown when a per-account resource limit is exceeded. For more information, see Application Auto Scaling Limits (http://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html#limits_as-app).

  • ConcurrentUpdateException Concurrent updates caused an exception, for example, if you request an update to an Application Auto Scaling resource that already has a pending update.

  • InternalServiceException The service encountered an internal error.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/applicationautoscaling"
)

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := applicationautoscaling.New(sess)

	params := &applicationautoscaling.RegisterScalableTargetInput{
		ResourceId:        aws.String("ResourceIdMaxLen1600"), // Required
		ScalableDimension: aws.String("ScalableDimension"),    // Required
		ServiceNamespace:  aws.String("ServiceNamespace"),     // Required

		MinCapacity:       aws.Int64(1),
		RoleARN:           aws.String("ResourceIdMaxLen1600"),
	}
	resp, err := svc.RegisterScalableTarget(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

}

An object representing a step adjustment for a StepScalingPolicyConfiguration. Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

For the following examples, suppose that you have an alarm with a breach threshold of 50:

  • If you want the adjustment to be triggered when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10.

  • If you want the adjustment to be triggered when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0.

There are a few rules for the step adjustments for your step policy:

  • The ranges of your step adjustments can't overlap or have a gap.

  • At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound.

  • At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound.

  • The upper and lower bound can't be null in the same step adjustment.

type StepScalingPolicyConfiguration

	// The adjustment type, which specifies how the ScalingAdjustment parameter
	// in a StepAdjustment is interpreted.
	AdjustmentType *string `type:"string" enum:"AdjustmentType"`

	// The amount of time, in seconds, after a scaling activity completes where
	// previous trigger-related scaling activities can influence future scaling
	// events.
	//
	// For scale out policies, while Cooldown 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. For example, an alarm
	// triggers a step scaling policy to scale out an Amazon ECS service by 2 tasks,
	// the scaling activity completes successfully, and a Cooldown period of 5 minutes
	// starts. During the Cooldown period, if the alarm triggers the same policy
	// again but at a more aggressive step adjustment to scale out the service by
	// 3 tasks, the 2 tasks that were added in the previous scale out event are
	// considered part of that capacity and only 1 additional task is added to the
	// desired count.
	//
	// For scale in policies, 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, Application
	// Auto Scaling scales out your scalable target immediately.
