public class NBHeartbeatComponent
extends NBStatusComponent

A heartbeat component is one which provides evidence that it is either in a healthy state or that it is not, via a heartbeat mechanism. This requires that a component property 'heartbeat' is provides which is the millisecond interval between beats.
