You can view the current status of a health check, as well as details on why it has failed, in the Amazon Route 53 console and via the Route 53 API.
Additionally, each health check’s results are published as Amazon CloudWatch metrics showing the endpoint’s health and, optionally, the latency of the endpoint’s response. You can view a graph of the Amazon CloudWatch metric in the health checks tab of the Amazon Route 53 console to see the current and historical status of the health check. You can also create Amazon CloudWatch alarms on the metric in order to send notifications if the status of the health check changes.
The Amazon CloudWatch metrics for all of your Amazon Route 53 health checks are also visible in the Amazon CloudWatch console. Each Amazon CloudWatch metric contains the Health Check ID (for example, 01beb6a3-e1c2-4a2b-a0b7-7031e9060a6a) which you can use to identify which health check the metric is tracking.
