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

             Summary: Show the Watermark metrics of source node in the web UI.
                 Key: FLINK-15784
                 URL: https://issues.apache.org/jira/browse/FLINK-15784
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Web Frontend
            Reporter: Guowei Ma


Currently, the web UI only shows the watermark of the non-source node. It might mislead some users that the source could not “receive” the watermark.[1]

So it would be more consistent to show all the watermarks metrics included the source node in the web UI.
