使用 描述 Application Auto Scaling 的排程擴展 AWS CLI

這些範例 AWS CLI 命令描述使用與 Application Auto Scaling 整合之 服務的資源擴展活動和排程動作。對於不同的可擴展目標，請在 中指定其命名空間--service-namespace、在 中指定其可擴展維度--scalable-dimension，以及在 中指定其資源 ID--resource-id。

使用 時 AWS CLI，請記住，您的命令會在為設定檔 AWS 區域 設定的 中執行。如果您想在不同區域中執行命令，則可變更設定檔的預設區域，或搭配 --region 參數使用命令。

描述服務的擴展活動

若要檢視指定服務命名空間中所有可擴展目標的擴展活動，請使用 describe-scaling-activities命令。

以下範例會擷取與 dynamodb 服務命名空間相關聯的擴展活動。

Linux、macOS 或 Unix

aws application-autoscaling describe-scaling-activities --service-namespace dynamodb

Windows

aws application-autoscaling describe-scaling-activities --service-namespace dynamodb
輸出

如果命令成功，則會傳回類似下列的輸出。

        },
        {

            "StatusCode": "Successful"
        }
    ]
}

若要將此命令變更為只擷取其中一個可擴展目標的擴展活動，請增加 --resource-id 選項。

描述服務的排程動作

若要描述指定服務命名空間中所有可擴展目標的排程動作，請使用 describe-scheduled-actions命令。

以下範例會擷取與 ec2 服務命名空間相關聯的排定動作。

Linux、macOS 或 Unix

aws application-autoscaling describe-scheduled-actions --service-namespace ec2

Windows

aws application-autoscaling describe-scheduled-actions --service-namespace ec2
輸出

如果命令成功，則會傳回類似下列的輸出。

描述可擴展目標的排程動作

若要擷取指定可擴展目標排程動作的相關資訊，請在使用 describe-scheduled-actions命令描述排程動作時新增 --resource-id選項。

如果您包含 --scheduled-action-names 選項並指定排定動作的名稱作為值，則此命令只會傳回名稱相符的排定動作，如下列範例所示。

Linux、macOS 或 Unix

aws application-autoscaling describe-scheduled-actions --service-namespace ec2 \
  --resource-id spot-fleet-request/sfr-40edeb7b-9ae7-44be-bef2-5c4c8EXAMPLE \
  --scheduled-action-names my-one-time-action

Windows

aws application-autoscaling describe-scheduled-actions --service-namespace ec2 ^
  --resource-id spot-fleet-request/sfr-40edeb7b-9ae7-44be-bef2-5c4c8EXAMPLE ^
  --scheduled-action-names my-one-time-action
輸出

如果命令成功，則會傳回類似下列的輸出。如果您為 提供多個值--scheduled-action-names，輸出會包含名稱相符的所有排程動作。
