    Affects Versions: 4.0.1
            Reporter: Jerry Chin


Hey fellows,

We're using _service discovery_ extension to refactor our raw zookeeper based 
service monitor.

Every time a service instance exits or joins, the monitor must be notified and 
push a notification to us, the only thing I found in _service discovery_ 
package meets the requirement is {{ServiceCacheListener}} interface, but when 
the interface is fired, there's no way we could know which service has changed.

Please help !

Thank in advance.
