copyapplyMutation, buildHealthCheckConfig.Builder ipAddress(String ipAddress)
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you
don't specify a value for IPAddress, Amazon 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 returned by DNS, Amazon 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 will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName.
Constraints: Amazon 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:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC, omit
IPAddress.
ipAddress - The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on.
If you don't specify a value for IPAddress, Amazon 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 returned by DNS, Amazon Route 53 then
checks the health of the endpoint.

HealthCheckConfig.Builder port(Integer port)
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for
Port only when you specify a value for IPAddress.
port - The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value
for Port only when you specify a value for IPAddress.HealthCheckConfig.Builder type(String type)
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
HTTP: Amazon Route 53 tries to establish a TCP connection. If successful, Amazon Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
HTTPS: Amazon Route 53 tries to establish a TCP connection. If successful, Amazon Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
If you specify HTTPS for the value of Type, the endpoint must support TLS v1.0 or
later.
HTTP_STR_MATCH: Amazon Route 53 tries to establish a TCP connection. If successful, Amazon Route 53
submits an HTTP request and searches the first 5,120 bytes of the response body for the string that you
specify in SearchString.
HTTPS_STR_MATCH: Amazon Route 53 tries to establish a TCP connection. If successful, Amazon Route 53
submits an HTTPS request and searches the first 5,120 bytes of the response body for the string
that you specify in SearchString.
TCP: Amazon Route 53 tries to establish a TCP connection.
CLOUDWATCH_METRIC: The health check is associated with a CloudWatch alarm. If the state of the alarm
is OK, the health check is considered healthy. If the state is ALARM, the health
check is considered unhealthy. If CloudWatch doesn't have sufficient data to determine whether the state is
OK or ALARM, the health check status depends on the setting for
InsufficientDataHealthStatus: Healthy, Unhealthy, or
LastKnownStatus.
CALCULATED: For health checks that monitor the status of other health checks, Amazon Route 53 adds up
the number of health checks that Amazon Route 53 health checkers consider to be healthy and compares that
number with the value of HealthThreshold.
For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide.

HealthCheckType,
HealthCheckTypeHealthCheckConfig.Builder resourcePath(String resourcePath)
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html.
resourcePath - The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can
be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint
is healthy, for example, the file /docs/route53-health-check.html.HealthCheckConfig.Builder fullyQualifiedDomainName(String fullyQualifiedDomainName)
Amazon Route 53 behavior depends on whether you specify a value for IPAddress.
If you specify a value for IPAddress:
Amazon 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 Amazon Route 53 to
perform health checks.
When Amazon 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, Amazon 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, Amazon 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, Amazon Route 53 passes FullyQualifiedDomainName:Port to the endpoint in the
Host header.
If you don't specify a value for FullyQualifiedDomainName, Amazon Route 53 substitutes the value
of IPAddress in the Host header in each of the preceding cases.
If you don't specify a value for IPAddress :
Amazon Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName
at the interval that you specify for RequestInterval. Using an IPv4 address that DNS returns,
Amazon Route 53 then checks the health of the endpoint.
If you don't specify a value for IPAddress, Amazon 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 you create a health check for which 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 that you specify for Type is HTTP, HTTPS,
HTTP_STR_MATCH, or HTTPS_STR_MATCH, Amazon 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, Amazon Route 53 doesn't
pass a Host header.
fullyQualifiedDomainName - Amazon Route 53 behavior depends on whether you specify a value for IPAddress.
If you specify a value for IPAddress:
Amazon 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
Amazon Route 53 to perform health checks.
When Amazon 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, Amazon 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, Amazon 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, Amazon Route 53 passes FullyQualifiedDomainName:Port to the endpoint
in the Host header.
If you don't specify a value for FullyQualifiedDomainName, Amazon Route 53 substitutes
the value of IPAddress in the Host header in each of the preceding cases.
If you don't specify a value for IPAddress :
Amazon Route 53 sends a DNS request to the domain that you specify for
FullyQualifiedDomainName at the interval that you specify for
RequestInterval. Using an IPv4 address that DNS returns, Amazon Route 53 then checks the
health of the endpoint.
If you don't specify a value for IPAddress, Amazon 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 you create a health check for which 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 that you specify for Type is HTTP,
HTTPS, HTTP_STR_MATCH, or HTTPS_STR_MATCH, Amazon 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, Amazon Route 53 doesn't pass a Host header.
HealthCheckConfig.Builder searchString(String searchString)
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH, the string that you want
Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the
response body, Amazon Route 53 considers the resource healthy.
Amazon Route 53 considers case when searching for SearchString in the response body.
searchString - If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH, the string that
you want Amazon Route 53 to search for in the response body from the specified resource. If the string
appears in the response body, Amazon Route 53 considers the resource healthy.
Amazon Route 53 considers case when searching for SearchString in the response body.
HealthCheckConfig.Builder requestInterval(Integer requestInterval)
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.
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval, the default value is 30 seconds.
requestInterval - 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.

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.
failureThreshold - 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.
HealthCheckConfig.Builder measureLatency(Boolean measureLatency)
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Amazon Route 53 console.
You can't change the value of MeasureLatency after you create a health check.
measureLatency - Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple

You can't change the value of MeasureLatency after you create a health check.
HealthCheckConfig.Builder inverted(Boolean inverted)
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
inverted - Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to
consider a health check unhealthy when it otherwise would be considered healthy.HealthCheckConfig.Builder healthThreshold(Integer healthThreshold)
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
HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
If you specify a number greater than the number of child health checks, Amazon Route 53 always considers this health check to be unhealthy.
If you specify 0, Amazon Route 53 always considers this health check to be healthy.
healthThreshold - 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 HealthCheckConfig$ChildHealthChecks and
HealthCheckConfig$ChildHealthChecks elements.
Note the following:
If you specify a number greater than the number of child health checks, Amazon Route 53 always considers this health check to be unhealthy.
If you specify 0, Amazon Route 53 always considers this health check to be healthy.

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.

will retry the handshake. In the second attempt, the health checker will omit
FullyQualifiedDomainName from the client_hello message.
HealthCheckConfig.Builder regionsWithStrings(Collection<String> regions)
A complex type that contains one Region element for each region from which you want Amazon Route
53 health checkers to check the specified endpoint.
If you don't specify any regions, Amazon Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values.
If you update a health check to remove a region that has been performing health checks, Amazon Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).

If you update a health check to remove a region that has been performing health checks, Amazon Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).

HealthCheckConfig.Builder alarmIdentifier(AlarmIdentifier alarmIdentifier)
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.
alarmIdentifier - A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to
use to determine whether this health check is healthy.default HealthCheckConfig.Builder alarmIdentifier(Consumer<AlarmIdentifier.Builder> alarmIdentifier)
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.
This is a convenience that creates an instance of theAlarmIdentifier.Builder avoiding the need to
create one manually via AlarmIdentifier.builder().
When the Consumer completes, SdkBuilder.build() is called immediately and its
result is passed to alarmIdentifier(AlarmIdentifier).alarmIdentifier - a consumer that will call methods on AlarmIdentifier.BuilderalarmIdentifier(AlarmIdentifier)HealthCheckConfig.Builder insufficientDataHealthStatus(String insufficientDataHealthStatus)
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: Amazon Route 53 considers the health check to be healthy.
Unhealthy: Amazon Route 53 considers the health check to be unhealthy.
LastKnownStatus: Amazon Route 53 uses the status of the health check from the last time that
CloudWatch had sufficient data to determine the alarm state. For new health checks that have no last known
status, the default status for the health check is healthy.
insufficientDataHealthStatus - 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: Amazon Route 53 considers the health check to be healthy.
