 	// Stops Route 53 from performing health checks. When you disable a health check,
 	// here's what happens:
 	//   - Health checks that check the health of endpoints: Route 53 stops submitting
 	//   requests to your application, server, or other resource.
 	//   - Calculated health checks: Route 53 stops aggregating the status of the
 	//   referenced health checks.
 	//   - Health checks that monitor CloudWatch alarms: Route 53 stops monitoring the
 	//   corresponding CloudWatch metrics.
 	// After you disable a health check, Route 53 considers the status of the health
 	// check to always be healthy. If you configured DNS failover, Route 53 continues
 	// to route traffic to the corresponding resources. If you want to stop routing
 	// traffic to a resource, change the value of Inverted (https://docs.aws.amazon.com/Route53/latest/APIReference/API_UpdateHealthCheck.html#Route53-UpdateHealthCheck-request-Inverted)
 	// . Charges for a health check still apply when the health check is disabled. For
 	// more information, see Amazon Route 53 Pricing (http://aws.amazon.com/route53/pricing/)
 	// .
 	Disabled *bool
 
 	// Specify whether you want Amazon Route 53 to send the value of
 	// FullyQualifiedDomainName to the endpoint in the client_hello message during TLS
 	// negotiation. This allows the endpoint to respond to HTTPS health check requests
 	// with the applicable SSL/TLS certificate. Some endpoints require that HTTPS
 	// requests include the host name in the client_hello message. If you don't enable
 	// SNI, the status of the health check will be SSL alert handshake_failure . A
 	// health check can also have that status for other reasons. If SNI is enabled and
 	// you're still getting the error, check the SSL/TLS configuration on your endpoint
 	// and confirm that your certificate is valid. The SSL/TLS certificate on your
 	// endpoint includes a domain name in the Common Name field and possibly several
 	// more in the Subject Alternative Names field. One of the domain names in the
 	// certificate should match the value that you specify for FullyQualifiedDomainName
 	// . If the endpoint responds to the client_hello message with a certificate that
 	// does not include the domain name that you specified in FullyQualifiedDomainName
 	// , a health checker will retry the handshake. In the second attempt, the health
 	// checker will omit FullyQualifiedDomainName from the client_hello message.
 	EnableSNI *bool
 
 	// The number of consecutive health checks that an endpoint must pass or fail for
 	// Amazon Route 53 to change the current status of the endpoint from unhealthy to

 	// Whether an Endpoint Is Healthy (https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover-determining-health-of-endpoints.html)
 	// in the Amazon Route 53 Developer Guide. If you don't specify a value for
 	// FailureThreshold , the default value is three health checks.
 	FailureThreshold *int32
 
 	// Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
 	// If a health check already has a value for IPAddress , you can change the value.
 	// However, you can't update an existing health check to add or remove the value of
 	// IPAddress . If you specify a value for IPAddress : Route 53 sends health check
 	// requests to the specified IPv4 or IPv6 address and passes the value of
 	// FullyQualifiedDomainName in the Host header for all health checks except TCP
 	// health checks. This is typically the fully qualified DNS name of the endpoint on
 	// which you want Route 53 to perform health checks. When Route 53 checks the
 	// health of an endpoint, here is how it constructs the Host header:
 	//   - If you specify a value of 80 for Port and HTTP or HTTP_STR_MATCH for Type ,
 	//   Route 53 passes the value of FullyQualifiedDomainName to the endpoint in the
 	//   Host header.
 	//   - If you specify a value of 443 for Port and HTTPS or HTTPS_STR_MATCH for Type
 	//   , Route 53 passes the value of FullyQualifiedDomainName to the endpoint in the
 	//   Host header.
 	//   - If you specify another value for Port and any value except TCP for Type ,
 	//   Route 53 passes FullyQualifiedDomainName : Port to the endpoint in the Host
 	//   header.
 	// If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes
 	// the value of IPAddress in the Host header in each of the above cases. If you
 	// don't specify a value for IPAddress : If you don't specify a value for IPAddress
 	// , Route 53 sends a DNS request to the domain that you specify in
 	// FullyQualifiedDomainName at the interval you specify in RequestInterval . Using
 	// an IPv4 address that is returned by DNS, Route 53 then checks the health of the
 	// endpoint. If you don't specify a value for IPAddress , you can’t update the
 	// health check to remove the FullyQualifiedDomainName ; if you don’t specify a
 	// value for IPAddress on creation, a FullyQualifiedDomainName is required. If you
 	// don't specify a value for IPAddress , Route 53 uses only IPv4 to send health
 	// checks to the endpoint. If there's no resource record set with a type of A for
 	// the name that you specify for FullyQualifiedDomainName , the health check fails
 	// with a "DNS resolution failed" error. If you want to check the health of
 	// weighted, latency, or failover resource record sets and you choose to specify
 	// the endpoint only by FullyQualifiedDomainName , 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-2-www.example.com ), not the name of the resource record sets
 	// (www.example.com). In this configuration, if the value of
 	// FullyQualifiedDomainName matches the name of the resource record sets and you
 	// then associate the health check with those resource record sets, health check
 	// results will be unpredictable. In addition, if the value of Type is HTTP , HTTPS
 	// , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of
 	// FullyQualifiedDomainName in the Host header, as it does when you specify a
 	// value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host
 	// header.
 	FullyQualifiedDomainName *string
 
 	// A sequential counter that Amazon Route 53 sets to 1 when you create a health
 	// check and increments by 1 each time you update settings for the health check. We
 	// recommend that you use GetHealthCheck or ListHealthChecks to get the current
 	// value of HealthCheckVersion for the health check that you want to update, and
 	// that you include that value in your UpdateHealthCheck request. This prevents
 	// Route 53 from overwriting an intervening update:
 	//   - If the value in the UpdateHealthCheck request matches the value of
 	//   HealthCheckVersion in the health check, Route 53 updates the health check with
 	//   the new settings.
 	//   - If the value of HealthCheckVersion in the health check is greater, the
 	//   health check was changed after you got the version number. Route 53 does not
 	//   update the health check, and it returns a HealthCheckVersionMismatch error.
 	HealthCheckVersion *int64
 
 	// The number of child health checks that are associated with a CALCULATED health
 	// that Amazon Route 53 must consider healthy for the CALCULATED health check to
 	// be considered healthy. To specify the child health checks that you want to
 	// associate with a CALCULATED health check, use the ChildHealthChecks and
 	// ChildHealthCheck elements. Note the following:
 	//   - If you specify a number greater than the number of child health checks,
 	//   Route 53 always considers this health check to be unhealthy.
 	//   - If you specify 0 , Route 53 always considers this health check to be
 	//   healthy.
 	HealthThreshold *int32
 
 	// The IPv4 or IPv6 IP address for the endpoint that you want Amazon Route 53 to
 	// perform health checks on. If you don't specify a value for IPAddress , Route 53
 	// sends a DNS request to resolve the domain name that you specify in
 	// FullyQualifiedDomainName at the interval that you specify in RequestInterval .
 	// Using an IP address that is returned by DNS, Route 53 then checks the health of
 	// the endpoint. Use one of the following formats for the value of IPAddress :
 	//   - IPv4 address: four values between 0 and 255, separated by periods (.), for
 	//   example, 192.0.2.44 .
 	//   - IPv6 address: eight groups of four hexadecimal values, separated by colons
 	//   (:), for example, 2001:0db8:85a3:0000:0000:abcd:0001:2345 . You can also
 	//   shorten IPv6 addresses as described in RFC 5952, for example,
 	//   2001:db8:85a3::abcd:1:2345 .
 	// If the endpoint is an EC2 instance, we recommend that you create an Elastic IP
 	// address, associate it with your EC2 instance, and specify the Elastic IP address
 	// for IPAddress . This ensures that the IP address of your instance never changes.
 	// For more information, see the applicable documentation:
 	//   - Linux: Elastic IP Addresses (EIP) (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html)
 	//   in the Amazon EC2 User Guide for Linux Instances
 	//   - Windows: Elastic IP Addresses (EIP) (https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/elastic-ip-addresses-eip.html)
 	//   in the Amazon EC2 User Guide for Windows Instances
 	// If a health check already has a value for IPAddress , you can change the value.
 	// However, you can't update an existing health check to add or remove the value of
 	// IPAddress . For more information, see FullyQualifiedDomainName (https://docs.aws.amazon.com/Route53/latest/APIReference/API_UpdateHealthCheck.html#Route53-UpdateHealthCheck-request-FullyQualifiedDomainName)
 	// . Constraints: Route 53 can't check the health of endpoints for which the IP
 	// address is in local, private, non-routable, or multicast ranges. For more
 	// information about IP addresses for which you can't create health checks, see the
 	// following documents:
 	//   - RFC 5735, Special Use IPv4 Addresses (https://tools.ietf.org/html/rfc5735)
 	//   - RFC 6598, IANA-Reserved IPv4 Prefix for Shared Address Space (https://tools.ietf.org/html/rfc6598)
