如何使用 CF 正确配置 Route53 HealthCheck 警报(在悉尼) [英] How to correctly configure Route53 HealthCheck Alarm with CF (in Sydney)

问题描述

我已将 Route53 HealthCheck 配置为与 CloudFormation 关联的警报，但结果运行状况检查显示未配置警报，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，则一切正常.

I've configured a Route53 HealthCheck with an associated alarm with CloudFormation, but the resulting healthcheck shows as having No alarms configured, and the alarms in the CloudWatch console remain dead. If I manually create the alarm in HealthChecks, everything works.

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

Worse, if I switch from Sydney/ap-southeast-2 and create the same cloud formation stack in North Virginia/us-east-1, the alarm is correctly associated with the health check and everything works!

另外一个数据点:在 Route53 HealthChecks 中手动创建警报时，警报是在 us-east-1 中创建的，尽管 Route53 是全局的且 ap-southeast-1> 是所有其他控制台的默认设置.

One more datapoint: when manually creating the alarm in Route53 HealthChecks, the alarm is created in us-east-1, despite Route53 being global and ap-southeast-1 being the default in all other consoles.

我的简化堆栈如下所示:

My simplified stack looks like this:

{
  "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"
            }
          }
        ]
      }
    }
  }
}

有什么理由让它在北弗吉尼亚有效而不在悉尼有效吗?

Is there any reason it should work in North Virginia but not in Sydney?

推荐答案

HealthCheck 生成的 CloudWatch 指标仅在美国东部地区可见，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.

The CloudWatch metrics generated by the HealthCheck are only visible in the US-East region, as described at the bottom of this page http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/health-checks-monitor-view-status.html. This is why your stack works correctly when created in us-east-1.
