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

             Summary: Dashboard jobs/tasks metrics display 0 when metrics are not yet available
                 Key: FLINK-7575
                 URL: https://issues.apache.org/jira/browse/FLINK-7575
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
    Affects Versions: 1.3.2
            Reporter: James Lafa
            Priority: Minor


The web frontend is currently displaying "0" when a metric is not available yet (ex: records-in/out, bytes-in/out).

0 is misleading and it's preferable to display no value while the value is still unknown.
