aws beanstalk cloudformation 添加 CPUCreditBalance 警报

Question

我正在尝试使用 cloudformation 将 CPUCreditBalance AWS::CloudWatch::Alarm 添加到 EBN 应用程序。和图片类似，但使用的是cloudformation

EC2 实例和自动缩放组也是由 cloudformation 创建的。所以我不知道如何让 InscanceId 或 AutoScalingGroupName 将其放置在此代码中

CPUCreditBalanceAlarm:
Type: AWS::CloudWatch::Alarm
Properties:
  AlarmDescription: Warning alarm when EC2 rans out of credit
  MetricName: CPUCreditBalance
  Namespace: AWS/EC2
  Period: 300
  Statistic: Average
  ComparisonOperator: LessThanThreshold
  Threshold: 1
  EvaluationPeriods: 2
  DatapointsToAlarm: 2
  TreatMissingData: breaching
  Dimensions:
    - Name: AutoScalingGroupName
      Value: XXXXXXXX
  AlarmActions:
    - !Ref SnsAlarmWarning

Answer 1

如果您将AWS::AutoScaling::AutoScalingGroup 定义在与警报相同的模板中，则只需使用Ref 即可获取ASG name：

  Dimensions:
    - Name: AutoScalingGroupName
      Value: !Ref AWSEBAutoScalingGroup
  AlarmActions:
    - !Ref SnsAlarmWarning
