Anton Mushin commented on FLINK-4564:
-------------------------------------

Not all clear.
How should look like MetricGroup#getMetricIdentifier() call in this case? 
If we use single reporter for other reporters and know their indexes, we must 
know name or index where we MetricGroup#getMetricIdentifier() call. and then in 
MetricRegistry need add method for getting indexes of reporters via names. 
or all this assumption is not correct?

> [metrics] Delimiter should be configured per reporter

> Currently, the delimiter used or the scope string is based on a configuration 
> setting shared by all reporters. However, different reporters may have 
> different requirements in regards to the delimiter, as such we should allow 
> reporters to use a different delimiter.
> We can keep the current setting as a global setting that is used if no 
> specific setting was set.
