+## Monitoring
+For monitoring the current number of masters in the cluster communicating with
each other to form a quorum, see the monitoring guide's [Replicated
Log](monitoring.md#replicated-log) on `registrar/log/ensemble_size`.
+For creating alerts covering failures in leader election, have a look at the
monitoring guide's [Basic Alerts](monitoring.md#basic-alerts) on
`master/elected`.

Mesos implements two levels of ZooKeeper leader election abstractions, one in
`src/zookeeper` and the other in `src/master` (look for
`contender|detector.hpp|cpp`).
