describe-scaling-plan-resources¶

Description¶

Describes the scalable resources in the specified scaling plan.

Synopsis¶

  describe-scaling-plan-resources
--scaling-plan-name <value>
--scaling-plan-version <value>
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--scaling-plan-name (string)

The name of the scaling plan.

--scaling-plan-version (long)

The version number of the scaling plan.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To describe the scalable resources for a scaling plan

The following describe-scaling-plan-resources example displays details about the single scalable resource (an Auto Scaling group) that is associated with the specified scaling plan.

aws autoscaling-plans describe-scaling-plan-resources \
    --scaling-plan-name my-scaling-plan \
    --scaling-plan-version 1

ScalingPolicies -> (list)

The scaling policies.

(structure)

Represents a scaling policy.

PolicyName -> (string)

The name of the scaling policy.

PolicyType -> (string)

The type of scaling policy.

TargetTrackingConfiguration -> (structure)

The target tracking scaling policy. Includes support for predefined or customized metrics.

PredefinedScalingMetricSpecification -> (structure)

A predefined metric. You can specify either a predefined metric or a customized metric.

PredefinedScalingMetricType -> (string)

The metric type. The ALBRequestCountPerTarget metric type applies only to Auto Scaling groups, Spot Fleet requests, and ECS services.

ResourceLabel -> (string)

Identifies the resource associated with the metric type. You can’t specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group for an Application Load Balancer attached to the Auto Scaling group, Spot Fleet request, or ECS service.

The format is app/<load-balancer-name>/<load-balancer-id>/targetgroup/<target-group-name>/<target-group-id>, where:

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

targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

CustomizedScalingMetricSpecification -> (structure)

A customized metric. You can specify either a predefined metric or a customized metric.

MetricName -> (string)

The name of the metric.

Namespace -> (string)

The namespace of the metric.

Dimensions -> (list)

The dimensions of the metric.

Conditional: If you published your metric with dimensions, you must specify the same dimensions in your customized scaling metric specification.

(structure)

Represents a dimension for a customized metric.

Value -> (string)

The value of the dimension.

Statistic -> (string)

The unit of the metric.

TargetValue -> (double)

The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

DisableScaleIn -> (boolean)

Indicates whether scale in by the target tracking scaling policy is disabled. If the value is true , scale in is disabled and the target tracking scaling policy doesn’t remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking scaling 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.

ScalingStatusCode -> (string)

The scaling status of the resource.

Active - The scaling configuration is active.

Inactive - The scaling configuration is not active because the scaling plan is being created or the scaling configuration could not be applied. Check the status message for more information.

PartiallyActive - The scaling configuration is partially active because the scaling plan is being created or deleted or the scaling configuration could not be fully applied. Check the status message for more information.

ScalingStatusMessage -> (string)

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

NextToken -> (string)

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