> Various reporters make use of a generalized scope string (e.g. "taskmanager.job.task.<metricname>"). This string can be generated with {{AbstractMetricGroup#getLogicalScope}}, which is however an internal API. As a result, the access pattern currently looks like this:
> {code}
> ((FrontMetricGroup<AbstractMetricGroup<?>>)group).getLogicalScope(CHARACTER_FILTER, '.')
> {code}
> Given the wide-spread of this kind of scope i propose to move it into the MetricGroup interface.
