アラートルールの設定 - Server Load Balancer - Alibaba Cloud ドキュメントセンター

CloudMonitorを有効化した後、API操作を呼び出すか、SDKを使用して、CloudMonitorコンソールでClassic Load Balancer (CLB) インスタンスのアラートルールを設定できます。

背景情報

CLBインスタンスまたはCLBリスナーが削除された場合、CLBインスタンスまたはリスナーに設定されたアラートルールも削除されます。

前提条件

CLBインスタンスが作成され、リスナーがCLBインスタンスに追加され、CLBインスタンスのヘルスチェックが有効になっています。詳細については、以下のトピックをご参照ください。
CloudMonitorでCLBのアラートルールを設定するために使用されるサービスラベルが取得されます。この例では、サービスラベルはSLBです。
CloudMonitorのCLBの名前空間が取得されます。この例では、名前空間はacs_slb_dashboardです。名前空間を取得する方法の詳細については、「DescribeProjectMeta」をご参照ください。

CloudMonitorコンソールでのアラートルールの設定

CLBコンソールにログインします。
上部のナビゲーションバーで、CLBインスタンスが存在します。
インスタンスページで、管理するインスタンスを見つけて、モニタリング列でのアイコンをクリックします。
[モニタリング情報] パネルで、[以前のバージョンに切り替え] をクリックします。以前のバージョンを使用する場合は、この手順をスキップします。
モニタリングデータパネルで、しきい値アラート設定をクリックします。
CloudMonitorコンソールのアラートルールページで、アラートルールの作成をクリックします。
[アラートルールの作成] パネルで、アラートルールを設定します。詳細については、「アラートルールの作成」をご参照ください。

API操作を呼び出してアラートルールを構成する

次の図は、API操作を呼び出してアラートルールを設定する手順を示しています。通过API设置报警规则_流程图

オプション: DescribeMetricMetaList操作を呼び出して、CloudMonitorで使用可能な時系列メトリックの説明を照会するか、Monitoring and alerting metricsでメトリックの説明を表示します。
PutContact操作を呼び出して、アラート連絡先を作成または変更します。
PutContactGroup操作を呼び出して、アラート連絡先グループを作成または変更します。
PutResourceMetricRule操作を呼び出して、リソースのパフォーマンスメトリックのしきい値トリガーアラートルールを設定します。
DescribeMetricRuleList操作を呼び出して、アラートルールを照会します。

この例では、TCPリスナーはlb-bp1rbwvouuyipbc *** インスタンスに設定されています。次のセクションでは、異常なECSインスタンスの数が指定されたしきい値を超えた場合に、Critical、Warn、およびInfoアラートをトリガーするルールを設定する方法について説明します。

DescribeMetricMetaList

DescribeMetricMetaList操作を呼び出して、CloudMonitorで使用可能な時系列メトリクスの説明を照会します。

リクエストパラメーター名前空間をacs_slb_dashboardに設定し、他のパラメータにはデフォルト値を使用します。
リクエストの例
```
http(s)://[Endpoint]/?Action=DescribeMetricMetaList
&Namespace=acs_slb_dashboard
&<Common request parameters>
```

返されたパラメーターに基づいて、CLBの時系列メトリックを表示します。この例でQpsパラメーターが返されているかどうかを確認します。
