Struct aws_sdk_servicediscovery::model::HealthCheckCustomConfig

#[non_exhaustive]
pub struct HealthCheckCustomConfig {
    pub failure_threshold: Option<i32>,
}

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.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

failure_threshold: Option<i32>

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.

Implementations

impl HealthCheckCustomConfig

pub fn failure_threshold(&self) -> Option<i32>

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.
