-----------------------------

             Summary: Add a metric for the network size of replicas for the 
registry.
                 Key: MESOS-7507
                 URL: https://issues.apache.org/jira/browse/MESOS-7507
             Project: Mesos
          Issue Type: Bug
          Components: master
            Reporter: Yan Xu


Maintaining quorum is an important aspect of the high availability of Mesos 
master but right now the best metric one can use is the number of master 
instances that are up. This is inadequate because this is not the same as the 
number of peers the replicas in the network can actually see. The proposed name 
for the new metric is {{registrar/log/recovered}}.
