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
}

Represents a CloudWatch alarm associated with a scaling policy.

func (Alarm) GoString

func (s Alarm) GoString() string

GoString returns the string representation

func (*Alarm) SetAlarmARN added in v1.5.0

func (s *Alarm) SetAlarmARN(v string) *Alarm

SetAlarmARN sets the AlarmARN field's value.

func (*Alarm) SetAlarmName added in v1.5.0

func (s *Alarm) SetAlarmName(v string) *Alarm

SetAlarmName sets the AlarmName field's value.

func (Alarm) String

func (s Alarm) String() string

String returns the string representation

type ApplicationAutoScaling

type ApplicationAutoScaling struct {
	*client.Client
}

With Application Auto Scaling, you can automatically scale your AWS resources. The experience similar to that of Auto Scaling (https://aws.amazon.com/autoscaling/). You can use Application Auto Scaling to accomplish the following tasks:

  • Define scaling policies to automatically scale your AWS resources

  • Scale your resources in response to CloudWatch alarms

  • View the history of your scaling events

Application Auto Scaling can scale the following AWS resources:

For a list of supported regions, see AWS Regions and Endpoints: Application Auto Scaling (http://docs.aws.amazon.com/general/latest/gr/rande.html#as-app_region) in the AWS General Reference. 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

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

DeleteScalingPolicy API operation for Application Auto Scaling.

Deletes the specified Application Auto Scaling scaling policy.

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 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
	}

func (*ApplicationAutoScaling) RegisterScalableTarget

RegisterScalableTarget API operation for Application Auto Scaling.

Registers or updates a scalable target. A scalable target is a resource that Application Auto Scaling can scale out or scale in. 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, you can create and apply scaling policies using PutScalingPolicy. You can view the scaling policies for a service namespace using DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it using 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

}
Output:

func (*ApplicationAutoScaling) RegisterScalableTargetRequest

func (c *ApplicationAutoScaling) RegisterScalableTargetRequest(input *RegisterScalableTargetInput) (req *request.Request, output *RegisterScalableTargetOutput)

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

See RegisterScalableTarget 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 RegisterScalableTarget 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 RegisterScalableTargetRequest method.
req, resp := client.RegisterScalableTargetRequest(params)

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

}

Represents 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:

  • To trigger the adjustment 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.

  • To trigger the adjustment 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.
