CpuTargetValue:
Type: String
Description:
zh-cn: PAS和AAS所在ECS的期望平均CPU使用率，平均CPU使用率=（PAS所在ECS实例+添加的AAS所在ECS实例+自动扩展的AAS所在ECS实例）CPU利用率总和/所有实例CPU总核数x100%。每分钟统计一次实际平均CPU使用率，当实际值连续超过期望值三次，则会触发自动扩展AAS动作。如果需要自定义统计周期和触发次数，请在执行完成后，在<a href='https://ess.console.aliyun.com/#/v3/welcome' target='_blank'>弹性伸缩控制台</a>添加相应的报警任务，详细内容请参考<a href='https://help.aliyun.com/document_detail/25907.html' target='_blank'>创建报警任务</a>
en: The expected average CPU usage of the ECS where the PAS and AAS are located. 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.
