> 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
