=head1 NAME

Paws::Route53::UpdateHealthCheck - Arguments for method UpdateHealthCheck on Paws::Route53

=head1 DESCRIPTION

This class represents the parameters used for calling the method UpdateHealthCheck on the
Amazon Route 53 service. Use the attributes of this class
as arguments to method UpdateHealthCheck.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to UpdateHealthCheck.

As an example:

  $service_obj->UpdateHealthCheck(Att1 => $value1, Att2 => $value2, ...);

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object.

=head1 ATTRIBUTES


=head2 AlarmIdentifier => L<Paws::Route53::AlarmIdentifier>





=head2 ChildHealthChecks => ArrayRef[Str|Undef]

A complex type that contains one C<ChildHealthCheck> element for each
health check that you want to associate with a C<CALCULATED> health
check.



=head2 EnableSNI => Bool

Specify whether you want Amazon Route 53 to send the value of
C<FullyQualifiedDomainName> to the endpoint in the C<client_hello>
message during C<TLS> negotiation. This allows the endpoint to respond
to C<HTTPS> health check requests with the applicable SSL/TLS
certificate.

Some endpoints require that HTTPS requests include the host name in the
C<client_hello> message. If you don't enable SNI, the status of the
health check will be SSL alert C<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
C<Common Name> field and possibly several more in the C<Subject
Alternative Names> field. One of the domain names in the certificate
should match the value that you specify for
C<FullyQualifiedDomainName>. If the endpoint responds to the
C<client_hello> message with a certificate that does not include the
domain name that you specified in C<FullyQualifiedDomainName>, a health
checker will retry the handshake. In the second attempt, the health
checker will omit C<FullyQualifiedDomainName> from the C<client_hello>
message.



=head2 FailureThreshold => Int

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
I<Amazon Route 53 Developer Guide>.

If you don't specify a value for C<FailureThreshold>, the default value
is three health checks.



=head2 FullyQualifiedDomainName => Str

Amazon Route 53 behavior depends on whether you specify a value for
C<IPAddress>.

If a health check already has a value for C<IPAddress>, you can change
the value. However, you can't update an existing health check to add or
remove the value of C<IPAddress>.

B<If you specify a value for> C<IPAddress>:

Amazon Route 53 sends health check requests to the specified IPv4 or
IPv6 address and passes the value of C<FullyQualifiedDomainName> in the
C<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 C<Host> header:

=over

=item *

If you specify a value of C<80> for C<Port> and C<HTTP> or
C<HTTP_STR_MATCH> for C<Type>, Amazon Route 53 passes the value of
C<FullyQualifiedDomainName> to the endpoint in the C<Host> header.

=item *

If you specify a value of C<443> for C<Port> and C<HTTPS> or
C<HTTPS_STR_MATCH> for C<Type>, Amazon Route 53 passes the value of
C<FullyQualifiedDomainName> to the endpoint in the C<Host> header.

=item *

If you specify another value for C<Port> and any value except C<TCP>
for C<Type>, Amazon Route 53 passes I<
C<FullyQualifiedDomainName>:C<Port> > to the endpoint in the C<Host>
header.

=back

If you don't specify a value for C<FullyQualifiedDomainName>, Amazon
Route 53 substitutes the value of C<IPAddress> in the C<Host> header in
each of the above cases.

B<If you don't specify a value for> C<IPAddress>:

If you don't specify a value for C<IPAddress>, Amazon Route 53 sends a
DNS request to the domain that you specify in
C<FullyQualifiedDomainName> at the interval you specify in
C<RequestInterval>. Using an IPv4 address that is returned by DNS,
Amazon Route 53 then checks the health of the endpoint.

If you don't specify a value for C<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
C<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
C<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 C<FullyQualifiedDomainName>, specify the domain name of the
server (such as C<us-east-2-www.example.com>), not the name of the
resource record sets (www.example.com).

In this configuration, if the value of C<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 C<Type> is C<HTTP>, C<HTTPS>,
C<HTTP_STR_MATCH>, or C<HTTPS_STR_MATCH>, Amazon Route 53 passes the
value of C<FullyQualifiedDomainName> in the C<Host> header, as it does
when you specify a value for C<IPAddress>. If the value of C<Type> is
C<TCP>, Amazon Route 53 doesn't pass a C<Host> header.



=head2 B<REQUIRED> HealthCheckId => Str

The ID for the health check for which you want detailed information.
When you created the health check, C<CreateHealthCheck> returned the ID
in the response, in the C<HealthCheckId> element.



=head2 HealthCheckVersion => Int

A sequential counter that Amazon Route 53 sets to C<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 C<GetHealthCheck> or C<ListHealthChecks> to
get the current value of C<HealthCheckVersion> for the health check
that you want to update, and that you include that value in your
C<UpdateHealthCheck> request. This prevents Amazon Route 53 from
overwriting an intervening update:

=over

=item *

If the value in the C<UpdateHealthCheck> request matches the value of
C<HealthCheckVersion> in the health check, Amazon Route 53 updates the
health check with the new settings.

=item *

If the value of C<HealthCheckVersion> in the health check is greater,
the health check was changed after you got the version number. Amazon
Route 53 does not update the health check, and it returns a
C<HealthCheckVersionMismatch> error.

=back




=head2 HealthThreshold => Int

The number of child health checks that are associated with a
C<CALCULATED> health that Amazon Route 53 must consider healthy for the
C<CALCULATED> health check to be considered healthy. To specify the
child health checks that you want to associate with a C<CALCULATED>
health check, use the C<ChildHealthChecks> and C<ChildHealthCheck>
elements.

Note the following:

=over

=item *

If you specify a number greater than the number of child health checks,
Amazon Route 53 always considers this health check to be unhealthy.

=item *

If you specify C<0>, Amazon Route 53 always considers this health check
to be healthy.

=back




=head2 InsufficientDataHealthStatus => Str

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:

=over

=item *

C<Healthy>: Amazon Route 53 considers the health check to be healthy.

=item *

C<Unhealthy>: Amazon Route 53 considers the health check to be
unhealthy.

=item *

C<LastKnownStatus>: Amazon Route 53 uses the status of the health check
from the last time 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.

=back


Valid values are: C<"Healthy">, C<"Unhealthy">, C<"LastKnownStatus">

=head2 Inverted => Bool

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.



=head2 IPAddress => Str

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
C<IPAddress>, Amazon Route 53 sends a DNS request to resolve the domain
name that you specify in C<FullyQualifiedDomainName> at the interval
that you specify in C<RequestInterval>. Using an IP address that is
returned by DNS, Amazon Route 53 then checks the health of the
endpoint.

Use one of the following formats for the value of C<IPAddress>:

=over

=item *

B<IPv4 address>: four values between 0 and 255, separated by periods
(.), for example, C<192.0.2.44>.

=item *

B<IPv6 address>: eight groups of four hexadecimal values, separated by
colons (:), for example, C<2001:0db8:85a3:0000:0000:abcd:0001:2345>.
You can also shorten IPv6 addresses as described in RFC 5952, for
example, C<2001:db8:85a3::abcd:1:2345>.

=back

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 C<IPAddress>. This ensures that the IP
address of your instance never changes. For more information, see the
applicable documentation:

=over

=item *

Linux: Elastic IP Addresses (EIP) in the I<Amazon EC2 User Guide for
Linux Instances>

=item *

Windows: Elastic IP Addresses (EIP) in the I<Amazon EC2 User Guide for
Windows Instances>

=back

If a health check already has a value for C<IPAddress>, you can change
the value. However, you can't update an existing health check to add or
remove the value of C<IPAddress>.

For more information, see
UpdateHealthCheckRequest$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:

=over

=item *

RFC 5735, Special Use IPv4 Addresses

=item *

RFC 6598, IANA-Reserved IPv4 Prefix for Shared Address Space

=item *

RFC 5156, Special-Use IPv6 Addresses

=back




=head2 Port => Int

The port on the endpoint on which you want Amazon Route 53 to perform
health checks.



=head2 Regions => ArrayRef[Str|Undef]

A complex type that contains one C<Region> element for each region that
you want Amazon Route 53 health checkers to check the specified
endpoint from.



=head2 ResourcePath => Str

The path 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.

Specify this value only if you want to change it.



=head2 SearchString => Str

If the value of C<Type> is C<HTTP_STR_MATCH> or C<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. (You can't change
the value of C<Type> when you update a health check.)
