Work Description: mxm commented on issue #8585: [BEAM-6829] Use transform
name for metric namespace if none provided
URL: https://github.com/apache/beam/pull/8585#issuecomment-498606551
@tweise You should be seeing only a fraction of the previous warnings. The
reason why you see some of the warnings is that there is no "PTRANSFORM" set
for the metric. In this case it looks like we do not have enough information to
de-duplicate metrics. This could also be an issue with how the Beam metric
label is populated.
> Instead, shouldn't the transform name be part of the scope?
The metric group is the best way to define the scope of a metric as part of
an ExecutableStage operator which serves metrics for multiple transforms
running inside an SDK Harness. We cannot make the transform name part of the
operator scope because it hosts multiple transforms with overlapping metric
names.
