描述資源調整政策
此範例命令說明 ecs 服務命名空間的資源調整原則。
命令:
aws application-autoscaling describe-scaling-policies --service-namespace
ecs
輸出:
{ "ScalingPolicies": [ { "PolicyName": "web-app-cpu-gt-75", "ScalableDimension": "ecs:service:DesiredCount", "ResourceId": "service/default/web-app", "CreationTime": 1462561899.23, "StepScalingPolicyConfiguration": { "Cooldown": 60, "StepAdjustments": [ { "ScalingAdjustment": 200, "MetricIntervalLowerBound": 0.0 } ], "AdjustmentType": "PercentChangeInCapacity" }, "PolicyARN": "arn:aws:autoscaling:us-west-2:012345678910:scalingPolicy:6d8972f3-efc8-437c-92d1-6270f29a66e7:resource/ecs/service/default/web-app:policyName/web-app-cpu-gt-75", "PolicyType": "StepScaling", "Alarms": [ { "AlarmName": "web-app-cpu-gt-75", "AlarmARN": "arn:aws:cloudwatch:us-west-2:012345678910:alarm:web-app-cpu-gt-75" } ], "ServiceNamespace": "ecs" }, { "PolicyName": "web-app-cpu-lt-25", "ScalableDimension": "ecs:service:DesiredCount", "ResourceId": "service/default/web-app", "CreationTime": 1462562575.099, "StepScalingPolicyConfiguration": { "Cooldown": 1, "StepAdjustments": [ { "ScalingAdjustment": -50, "MetricIntervalUpperBound": 0.0 } ], "AdjustmentType": "PercentChangeInCapacity" }, "PolicyARN": "arn:aws:autoscaling:us-west-2:012345678910:scalingPolicy:6d8972f3-efc8-437c-92d1-6270f29a66e7:resource/ecs/service/default/web-app:policyName/web-app-cpu-lt-25", "PolicyType": "StepScaling", "Alarms": [ { "AlarmName": "web-app-cpu-lt-25", "AlarmARN": "arn:aws:cloudwatch:us-west-2:012345678910:alarm:web-app-cpu-lt-25" } ], "ServiceNamespace": "ecs" } ] }

範例 1:此指令程式說明指定服務命名空間的「Application Auto Scaling 整資源調整」原則。
Get-AASScalingPolicy -ServiceNamespace AppStream
輸出:
Alarms : {Appstream2-LabFleet-default-scale-out-Alarm} CreationTime : 9/3/2019 2:48:15 AM PolicyARN : arn:aws:autoscaling:us-west-2:012345678912:scalingPolicy:5659b069-b5cd-4af1-9f7f-3e956d36233e:resource/appstream/fleet/LabFleet: policyName/default-scale-out PolicyName : default-scale-out PolicyType : StepScaling ResourceId : fleet/LabFleet ScalableDimension : appstream:fleet:DesiredCapacity ServiceNamespace : appstream StepScalingPolicyConfiguration : Amazon.ApplicationAutoScaling.Model.StepScalingPolicyConfiguration TargetTrackingScalingPolicyConfiguration : Alarms : {Appstream2-LabFleet-default-scale-in-Alarm} CreationTime : 9/3/2019 2:48:15 AM PolicyARN : arn:aws:autoscaling:us-west-2:012345678912:scalingPolicy:5659b069-b5cd-4af1-9f7f-3e956d36233e:resource/appstream/fleet/LabFleet: policyName/default-scale-in PolicyName : default-scale-in PolicyType : StepScaling ResourceId : fleet/LabFleet ScalableDimension : appstream:fleet:DesiredCapacity ServiceNamespace : appstream StepScalingPolicyConfiguration : Amazon.ApplicationAutoScaling.Model.StepScalingPolicyConfiguration TargetTrackingScalingPolicyConfiguration :

注意
還有更多關於 GitHub。尋找完整範例,並了解如何在 AWS 程式碼範例儲存庫
中設定和執行。 async fn show_policies(client: &Client) -> Result<(), Error> { let response = client .describe_scaling_policies() .service_namespace(ServiceNamespace::Ec2) .send() .await?; println!("Auto Scaling Policies:"); for policy in response.scaling_policies() { println!("{:?}\n", policy); } println!("Next token: {:?}", response.next_token()); Ok(()) }
