[jira] [Created] (CURATOR-349) Expose extra metrics in TracerDeriver

Fangmin Lv created CURATOR-349:
----------------------------------

             Summary: Expose extra metrics in TracerDeriver
                 Key: CURATOR-349
                 URL: https://issues.apache.org/jira/browse/CURATOR-349
             Project: Apache Curator
          Issue Type: New Feature
          Components: Recipes
            Reporter: Fangmin Lv


Allow service instances to be temporarily removed from discovery (when using the Service Discovery recipe). 

This can be achieved with a new 'enabled' flag that is included as part of the service instance node data in Zookeeper. Updating this flag via e.g. Exhibitor will allow an instance to be disabled. When the flag is omitted, the service is assumed to be enabled, hence this change is backward compatible.
