Our config center may not use ServiceCenter,Apollo is coming. And Health check is more wide mechanism also can used for check DB,other microservice or any other resource(this microservice related),one Microservice can have many HealthChecker; So I think "if not health, then SDK will stop heartBeat to SC or report status to SC" is a Ops policy and we can support later ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
