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

             Summary: Add a system metric to show the checkpoint restore time
                 Key: FLINK-19010
                 URL: https://issues.apache.org/jira/browse/FLINK-19010
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics
    Affects Versions: 1.11.1
            Reporter: Zhinan Cheng


Now the system metric only shows the downtime when failure happens. It would be interesting to see the time to restore the checkpoint, so users can better understand the bottleneck of failure recovery.
