テンプレート名
ACS-SAP-SAPAutoScaling
テンプレートの説明
既存の Systems、Applications、and Products（SAP）システムのプライマリ アプリケーション サーバ（PAS）に基づいて、オートスケーリンググループを作成し、自動または手動で Elastic Compute Service（ECS）インスタンスを追加し、追加アプリケーション サーバ（AAS）としてデプロイします。 AAS は、SAP ログオングループ（SMLG）に自動的に参加します。

Description:
en: SMLG login group name. The extended AAS will be automatically added to the SMLG login group. If it is not filled in, it will be automatically added to the default 'SPACE' group. If the SMLG group is not set, it is not required to fill in.

Average CPU usage = (the ECS instance where the PAS is located + the ECS instance where the added AAS is located + the ECS instance where the automatically expanded AAS is located) the sum of the CPU utilization / the total number of CPU cores in all instances x100 %. The actual average CPU usage is counted every minute. When the actual value exceeds the expected value three times in a row, the automatic expansion AAS action will be triggered. If you need to customize the statistics period and trigger times, please click the <a href='https://ess.console.aliyun.com/#/v3/welcome' target='_blank'> elastic scaling console after the execution is completed. </a>Add the corresponding alarm task.
