Hi Joshua,
Looks like a bug, the UI parsing we saw in Flink 1.5.0 and 1.6.0 is normal.
Please feel free to create a JIRA issue.
In addition, I suggest you upgrade your Flink version.
Thanks, vino.

Hi All
came into new situations, that the UI can show metric data but the data
remains the same all the time after days. So, there are two cases, one is
no data in UI at all, another is dead data in UI all the time.
when dig into the taskmanager.log, taskmanager.error, taskmanager.out,
there is nothing unnormal found.
anyone can give some hints?
Yours sincerely
Joshua
