amazon-web-services - 如何使用 CF 正确配置 Route53 HealthCheck 警报(悉尼)

Question

我已通过 CloudFormation 配置了具有关联警报的 Route53 HealthCheck，但生成的运行状况检查显示为未配置警报，并且 CloudWatch 控制台中的警报仍然无效。如果我在 HealthChecks 中手动创建警报，一切正常。

更糟糕的是，如果我从悉尼/ap-southeast-2切换并在北弗吉尼亚州/us-east-1创建相同的云层堆栈，则警报为与健康检查正确关联，一切正常!

还有一个数据点:在 Route53 HealthChecks 中手动创建警报时，警报会在 us-east-1 中创建，尽管 Route53 是全局的并且 ap-southeast-1 > 是所有其他控制台的默认设置。

我的简化堆栈如下所示:

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": "healthcheck alarm test",
  "Resources": {
    "StatusHealthCheck": {
      "Type": "AWS::Route53::HealthCheck",
      "Properties": {
        "HealthCheckConfig": {
          "Port": "80",
          "Type": "HTTP",
          "ResourcePath": "/status",
          "FullyQualifiedDomainName": "testdomain.com",
          "RequestInterval": "30",
          "FailureThreshold": "1"
        },
        "HealthCheckTags": [
          {
            "Key": "Name",
            "Value": "status reachability check"
          }
        ]
      }
    },
    "StatusHealthCheckFailedAlarm": {
      "Type": "AWS::CloudWatch::Alarm",
      "Properties": {
        "ActionsEnabled": "true",
        "AlarmDescription": "alarmed when status doesn't respond",
        "ComparisonOperator": "LessThanThreshold",
        "EvaluationPeriods": "1",
        "MetricName": "HealthCheckStatus",
        "Namespace": "AWS/Route53",
        "Period": "60",
        "Statistic": "Minimum",
        "Threshold": "1.0",
        "Dimensions": [
          {
            "Name": "HealthCheckId",
            "Value": {
              "Ref": "StatusHealthCheck"
            }
          }
        ]
      }
    }
  }
}

有什么理由它应该在北弗吉尼亚州起作用，但在悉尼不起作用？

HealthCheck 生成的 CloudWatch 指标仅在美国东部区域可见，如本页底部所述 http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/health-checks-monitor-view-status.html 。这就是为什么您的堆栈在 us-east-1 中创建时可以正常工作的原因。
