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

             Summary: Master task state metrics discrepancy
                 Key: MESOS-8493
                 URL: https://issues.apache.org/jira/browse/MESOS-8493
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 1.2.0
            Reporter: Ilya Pronin


Currently if the task status update has no reason we don't increment {{master/<state>/<source>/<reason>}}
metric. Because of that {{master/task_<status>/*}} counters may not sum up to {{master/tasks_<status>}}
counter, if for example a custom executor doesn't set a reason to its status updates.

Since the zero value in {{Reason}} enum is already taken it is possible to just count status
updates with no reason an under artificial {{reason_unknown}} name.
