NAME

Paws::ServiceDiscovery::HealthCheckCustomConfig

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ServiceDiscovery::HealthCheckCustomConfig object:

$service_obj->Method(Att1 => { FailureThreshold => $value, ..., FailureThreshold => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ServiceDiscovery::HealthCheckCustomConfig object:

$result = $service_obj->Method(...);
$result->Att1->FailureThreshold

DESCRIPTION

A complex type that contains information about an optional custom health check. A custom health check, which requires that you use a third-party health checker to evaluate the health of your resources, is useful in the following circumstances:

  • You can't use a health check that's defined by HealthCheckConfig because the resource isn't available over the internet. For example, you can use a custom health check when the instance is in an Amazon VPC. (To check the health of resources in a VPC, the health checker must also be in the VPC.)

  • You want to use a third-party health checker regardless of where your resources are located.

If you specify a health check configuration, you can specify either HealthCheckCustomConfig or HealthCheckConfig but not both.

To change the status of a custom health check, submit an UpdateInstanceCustomHealthStatus request. Cloud Map doesn't monitor the status of the resource, it just keeps a record of the status specified in the most recent UpdateInstanceCustomHealthStatus request.

Here's how custom health checks work:

  1. You create a service.

  2. You register an instance.

  3. You configure a third-party health checker to monitor the resource that's associated with the new instance.

    Cloud Map doesn't check the health of the resource directly.

  4. The third-party health-checker determines that the resource is unhealthy and notifies your application.

  5. Your application submits an UpdateInstanceCustomHealthStatus request.

  6. Cloud Map waits for 30 seconds.

  7. If another UpdateInstanceCustomHealthStatus request doesn't arrive during that time to change the status back to healthy, Cloud Map stops routing traffic to the resource.

ATTRIBUTES

FailureThreshold => Int

This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an UpdateInstanceCustomHealthStatus request before changing the status of the service instance.

The number of 30-second intervals that you want Cloud Map to wait after receiving an UpdateInstanceCustomHealthStatus request before it changes the health status of a service instance.

Sending a second or subsequent UpdateInstanceCustomHealthStatus request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits 30 seconds after the first request to make the change.
