Interface HealthCheckCallback

public interface HealthCheckCallback

Applications can implement this interface and register a callback with the DiscoveryClient.registerHealthCheckCallback(HealthCheckCallback).

Your callback will be invoked every EurekaInstanceConfig.getLeaseRenewalIntervalInSeconds() if the instance is in InstanceInfo.InstanceStatus.STARTING status, we will delay the callback until the status changes.Returning a false to the checkHealth() method will mark the instance InstanceInfo.InstanceStatus.DOWN with eureka.

Eureka server normally just relies on heartbeats to identify the status of an instance. Application could decide to implement their own healthpage check here or use the built-in jersey resource HealthCheckResource.
