Interface HealthCheckCallback

Deprecated.

Use HealthCheckHandler instead.

@Deprecated
public interface HealthCheckCallback

Applications can implement this interface and register a callback with the EurekaClient.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.
