This action creates a new health check.
To create a new health check, send a POST request to the /Route 53 API version/healthcheck resource. The request body must include a document with a CreateHealthCheckRequest element. The response returns the CreateHealthCheckResponse element that contains metadata about the health check.

string
[REQUIRED]
A unique string that identifies the request and that allows failed CreateHealthCheck requests to be retried without the risk of executing the operation twice. You must use a unique CallerReference string every time you create a health check. CallerReference can be any unique string; you might choose to use a string that identifies your project.
Valid characters are any Unicode code points that are legal in an XML 1.0 document. The UTF-8 encoding of the value must be less than 128 bytes.
dict

A complex type that contains health check configuration.
IPAddress (string) --
IP Address of the instance being checked.
Port (integer) --
Port on which connection will be opened to the instance to health check. For HTTP and HTTP_STR_MATCH this defaults to 80 if the port is not specified. For HTTPS and HTTPS_STR_MATCH this defaults to 443 if the port is not specified.
Type (string) -- [REQUIRED]
The type of health check to be performed. Currently supported types are TCP, HTTP, HTTPS, HTTP_STR_MATCH, HTTPS_STR_MATCH, CALCULATED and CLOUDWATCH_METRIC.

A string to search for in the body of a health check response. Required for HTTP_STR_MATCH and HTTPS_STR_MATCH health checks. Amazon Route 53 considers case when searching for SearchString in the response body.
RequestInterval (integer) --
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health-check request.
Each Amazon Route 53 health checker makes requests at this interval. Valid values are 10 and 30. The default value is 30.

(string) --
An Amazon EC2 region that you want Amazon Route 53 to use to perform health checks.

[REQUIRED]
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.
Amazon Route 53 determines whether a resource record set is healthy by periodically sending a request to the endpoint that is specified in the health check. If that endpoint returns an HTTP status code of 2xx or 3xx, the endpoint is healthy. If the endpoint returns an HTTP status code of 400 or greater, or if the endpoint doesn't respond for a certain amount of time, Amazon Route 53 considers the endpoint unhealthy and also considers the resource record set unhealthy.
The HealthCheckId element is only useful when Amazon Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Amazon Route 53 to base the choice in part on the status of a health check. Configuring health checks only makes sense in the following configurations:
You're checking the health of the resource record sets in a weighted, latency, geolocation, or failover resource record set, and you specify health check IDs for all of the resource record sets. If the health check for one resource record set specifies an endpoint that is not healthy, Amazon Route 53 stops responding to queries using the value for that resource record set.
You set EvaluateTargetHealth to true for the resource record sets in an alias, weighted alias, latency alias, geolocation alias, or failover alias resource record set, and you specify health check IDs for all of the resource record sets that are referenced by the alias resource record sets. For more information about this configuration, see EvaluateTargetHealth. Amazon Route 53 doesn't check the health of the endpoint specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Amazon Route 53 checks the health of the endpoint that you specified in the health check.
For geolocation resource record sets, if an endpoint is unhealthy, Amazon Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the United States, for North America, and for all locations. If the endpoint for the state resource record set is unhealthy, Amazon Route 53 checks the resource record sets for the United States, for North America, and for all locations (a resource record set for which the value of CountryCode is *), in that order, until it finds a resource record set for which the endpoint is healthy.
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName, specify the domain name of the server (such as us-east-1-www.example.com), not the name of the resource record sets (example.com).

To retrieve a list of your health checks, send a GET request to the /Route 53 API version/healthcheck resource. The response to this request includes a HealthChecks element with zero, one, or multiple HealthCheck child elements. By default, the list of health checks is displayed on a single page. You can control the length of the page that is displayed by using the MaxItems parameter. You can use the Marker parameter to control the health check that the list begins with.
