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

             Summary: Show non-numeric metrics in Web UI
                 Key: FLINK-15753
                 URL: https://issues.apache.org/jira/browse/FLINK-15753
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Web Frontend
    Affects Versions: 1.10.0
            Reporter: Nico Kruber


Flink's Web UI seems to be tailored to numeric values only. For metrics like {{isBackPressured}} which is {{boolean}}, it only shows {{NaN}} and nothing in the graph either.

It would be nice to have a plain text view instead of "Numeric" there so we can see arbitrary values (using {{.toString()}} internally or so).
