AlarmIdentifier *types.AlarmIdentifier
// A complex type that contains one ChildHealthCheck element for each health check

ChildHealthChecks []string
// 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].
//
// Charges for a health check still apply when the health check is disabled. For
// more information, see [Amazon Route 53 Pricing].
//
// [Inverted]: https://docs.aws.amazon.com/Route53/latest/APIReference/API_UpdateHealthCheck.html#Route53-UpdateHealthCheck-request-Inverted
// [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
// healthy or vice versa. For more information, see [How Amazon Route 53 Determines Whether an Endpoint Is Healthy]in the Amazon Route 53
// Developer Guide.
//
// If you don't specify a value for FailureThreshold , the default value is three
// health checks.
//
// [How Amazon Route 53 Determines Whether an Endpoint Is Healthy]: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover-determining-health-of-endpoints.html
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)]in the Amazon EC2 User Guide for Linux Instances
//
// - Windows: [Elastic IP Addresses (EIP)]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].
//
// 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]
//

IPAddress *string
// When CloudWatch has insufficient data about the metric to determine the alarm
// state, the status that you want Amazon Route 53 to assign to the health check:
//
// - Healthy : Route 53 considers the health check to be healthy.
//
// - Unhealthy : Route 53 considers the health check to be unhealthy.
//
// - LastKnownStatus : By default, Route 53 uses the status of the health check
