与 AWS SDK或DescribeScalableTargets一起使用 CLI

以下代码示例演示如何使用 DescribeScalableTargets。

CLI

AWS CLI

描述可扩展的目标

以下describe-scalable-targets示例描述了ecs服务命名空间的可扩展目标。

aws application-autoscaling describe-scalable-targets \
    --service-namespace ecs

输出：

{
    "ScalableTargets": [
        {
            "ServiceNamespace": "ecs",
            "ScalableDimension": "ecs:service:DesiredCount",
            "ResourceId": "service/default/web-app",
            "MinCapacity": 1,
            "MaxCapacity": 10,
            "RoleARN": "arn:aws:iam::123456789012:role/aws-service-role/ecs.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_ECSService",
            "CreationTime": 1462558906.199,
            "SuspendedState": {
                "DynamicScalingOutSuspended": false,
                "ScheduledScalingSuspended": false,
                "DynamicScalingInSuspended": false
            },
            "ScalableTargetARN": "arn:aws:application-autoscaling:us-west-2:123456789012:scalable-target/1234abcd56ab78cd901ef1234567890ab123"
        }
    ]
}

PowerShell

用于 PowerShell

示例 1：此示例将提供有关指定命名空间中应用程序自动缩放可扩展目标的信息。

Get-AASScalableTarget -ServiceNamespace "AppStream"

输出：

CreationTime      : 11/7/2019 2:30:03 AM
MaxCapacity       : 5
MinCapacity       : 1
ResourceId        : fleet/Test
RoleARN           : arn:aws:iam::012345678912:role/aws-service-role/appstream.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_AppStreamFleet
