healthCheckCustomConfig

Information about an optional custom health check. A custom health check, which requires that you use a third-party health checker to evaluate the health of your resources, is useful in the following circumstances:

• You can't use a health check that's defined by HealthCheckConfig because the resource isn't available over the internet. For example, you can use a custom health check when the instance is in an Amazon VPC. (To check the health of resources in a VPC, the health checker must also be in the VPC.)

• You want to use a third-party health checker regardless of where your resources are located.

If you specify a health check configuration, you can specify either HealthCheckCustomConfig or HealthCheckConfig but not both.
