[jira] [Created] (ZOOKEEPER-3858) Add metrics to track server unavailable time

Jie Huang created ZOOKEEPER-3858:
------------------------------------

             Summary: Add metrics to track server unavailable time
                 Key: ZOOKEEPER-3858
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3858
             Project: ZooKeeper
          Issue Type: Sub-task
          Components: metric system
            Reporter: Jie Huang
             Fix For: 3.6.2


These metrics track the time when a ZooKeeper server is up and running but not serving client traffic because it is not part of a quorum. They don't track the hardware down time or ZooKeeper process down time.  

UNAVAILABLE_TIME: time between LOOKING and BROADCAST

LEADER_UNAVAILABLE_TIME: time between LOOKING and BROADCAST on the leader
