The isBackPressured metric is a Boolean -- it reports true or false, rather
than 1 or 0. The Flink web UI can not display it (it shows NaN); perhaps
the same is true for Datadog.
https://issues.apache.org/jira/browse/FLINK-15753 relates to this.

Thanks for your reply. I'm using Flink 1.12. I'm checking in Datadog and
the metric is not available there.
It has other task/operator metrics such as numRecordsIn/numRecordsOut there
but not the isBackPressured.

Hi,
The metric is registered upon task deployment and reported periodically.
Which Flink version are you using? The metric was added in 1.10.
Are you checking it in the UI?

Hello,
The documentation here
https://ci.apache.org/projects/flink/flink-docs-stable/ops/metrics.html
states there is a isBackPressured metric available yet I don't see it. Any
ideas why?
Thanks
