[~chesnay] I guess you'll get this message on Monday. I have the impression
that everything is already in place for this ticket. Backends that need to
filter certain characters from the component names already define a filter as
in [here for
dropwizard|#https://github.com/apache/flink/blob/22679aacd04612fb01f96bbbe58012cc7b2cda58/flink-metrics/flink-metrics-dropwizard/src/main/java/org/apache/flink/dropwizard/ScheduledDropwizardReporter.java#L185]
and pass it to ProxyMetricGroup#getMetricIdentifier. What did I miss?

> Automatically replace delimiter in metric name components
> ---------------------------------------------------------
>
> Key: FLINK-19656
> URL: https://issues.apache.org/jira/browse/FLINK-19656
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Chesnay Schepler
> Priority: Major
> Labels: starter
> Fix For: 1.12.0
>
>
> The metric name consists of various components (like job ID, task ID), that
> are then joined by a delimiter(commonly {{.}}).
> The delimiter isn't just for convention, but also carries semantics for many
> metric backends, as they organize metrics based on the delimiter.
> This can behave in unfortunate ways if the delimiter is contained with a
> given component, as it will now be split up by the backend.
> We should automatically filter such occurrences to prevent this from
> happening.
