Amazon web services AWS route53使用cloudwatch警报进行故障切换

我正试图通过使用cloudwatch警报通过AWS route53 healthcheck实现故障转移

我添加了以下主要和次要A记录（记录集）

健康检查设置

IP = Ip address 
Host name = www2 
URL = /abc/
Protocol = HTTP 
String = abc

CloudWatch警报设置

Whenever = Maximum of Health Check Status 
IS <= 0 
For at Least = 2 
Consecutive period of = 5 minutes 

where=健康检查状态的最大值
我在AWS表格上提出了同样的问题，下面是答案

As far as I know, the alarms can not be used to control Route 53 failover. The health check interval, number of failures required to trigger failover, and all that is currently not configurable. You could probably use a higher TTL for the primary record to delay the failover for some users, though.
