Your best bet is to create a custom reporter that does this calculation.
You could either wrap the reporter, subclass is, or fork it.
In any case,
https://github.com/apache/flink/tree/master/flink-metrics/flink-metrics-datadog
should be a good starting point.

Hi Team,
We are using datadog and its http reporter( packaged in flink image) for
sending metrics from flink application. We do have a requirement for
setting tags with values calculated at runtime for the custom metrics
emitted from Flink. Currently, it is impossible to assign tags at runtime.
