amazon-web-services - 云信息健康检查 "Invalid Request"

Question

我正在尝试使用 Cloudformation 部署此 Cloudwatch 警报和运行状况检查，但收到一条错误消息，指出请求对于运行状况检查无效，并且无法理解原因。希望有人能帮我解决这个问题。

  rEventBusCwAlarm:
    Type: AWS::CloudWatch::Alarm
    Properties:
      ActionsEnabled: FALSE
      AlarmDescription: Alarm that monitors the health of event busses in current region by counting Failed Invocations
      ComparisonOperator: GreaterThanThreshold
      EvaluationPeriods: 5
      MetricName: FailedInvocations
      Namespace: AWS/Events
      Threshold: 10
      Statistic: Sum
      Period: 10


  rEventBusHealthCheck:
    Type: AWS::Route53::HealthCheck
    Properties:
      HealthCheckConfig:
        Type: CLOUDWATCH_METRIC
        InsufficientDataHealthStatus: Healthy
        AlarmIdentifier:
            Name: !Ref rEventBusCwAlarm
            Region: !Sub ${pRegion}

这是我得到的确切错误:

Resource handler returned message: "Invalid request provided: AWS::Route53::HealthCheck" (RequestToken: 281f0512-ba1d-3c44-4c44-d371f07fae81, HandlerErrorCode: InvalidRequest)

问题在于警报，而不是健康检查。如果您尝试不通过 Cloudformation 创建此警报，您将得到:

“AWS/”命名空间中的指标仅支持大于 60 秒的周期

所以改变

周期:10

至

周期:60(或更多)

这看起来像是一个 Cloudformation 错误，您应该无法创建该警报。
