Route 53™ Resource Monitoring and Recovery

The Route 53 resource monitors the normality of the retrieval of the DNS A record registered at the time of creation and the association with the virtual IP address. The monitoring process is as follows.

1. Obtain the address set in the Route 53 A record with API. If it fails to obtain the record, it will retry 3 additional times waiting 2 seconds between attempts (by default). After the third unsuccessful attempt it will stop the monitoring and record the failure in the log.

2. Obtain an IP address from the dependent IP resource and compare it with the IP address in the DNS A record information. If the IP address information matches, then exit with a success as no errors exist. If the IP addresses do not match then exit with a failure to initiate a local recovery.
