-----------------------------------
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).
