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

             Summary: Add JM metric which shows the restart duration
                 Key: FLINK-4202
                 URL: https://issues.apache.org/jira/browse/FLINK-4202
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.1.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.1.0


It is convenient for users to have a metric which tells you how long the restarting of a job
has taken.

I propose a to introduce a {{Gauge}} which returns the time between {{JobStatus.RESTARTING}}
and {{JobStatus.RUNNING}}. If the job was not restarted (initial run), then this metric will
return {{-1}}.
