Route53 HealthCheckConfigProperty: requestInterval valid values missing

[mausman4]

Describe the issue

requestInterval, which sets the interval in seconds between receipt of Route53 health check ping and next ping can not be any value; valid values appear to be 10 (Fast) or 30 (default). The documentation is misleading in that it does not communicate this; it only specifies that the value for requestInterval must be a number. Other documentation indicates that the value for requestInterval should be a range, with min value of 10 and max of 30. Again, this is also misleading.

Data that led me to this conclusion:

• new Route53 health check resource continually failed to deploy when requestInterval was set to 15. Only when this value was changed to 10 did it succeed.

• When manually creating health checks in the console, the only values available to select are either 10 or 30.,

What is the full error message when requestInterval was set to 15?

Either way, if this is to be documented properly it needs to be done so upstream with the services, then it will be propagated to us. On the CloudFormation page you linked, the best way to provide feedback is to click the provide feedback button at the bottom of the screen.

Though, if we could document the min and max values of arbitrary properties, I think that would lead to more clear Cfn resource docs at times. We could take that as a feature request for docs generation as a whole

It looks like the CDK docs now say:

"If you don't specify a value for RequestInterval , the default value is 30 seconds."

But the doc generation does not include the min value referenced here.
