---------------------------------
Resolution: Fixed
> Group coordinator and share coordinator runtime metrics are aliased
> -------------------------------------------------------------------
>
> Key: KAFKA-19445
> URL: https://issues.apache.org/jira/browse/KAFKA-19445
> Project: Kafka
> Issue Type: Bug
> Components: group-coordinator
> Reporter: Sean Quah
> Assignee: Sean Quah
> Priority: Major
>
> Both the group coordinator and share coordinator runtime metrics use the same
> sensor names and so end up with the same {{Sensors}}. These sensors have both
> the group and share coordinator metrics as children. When data is reported to
> a sensor, the data gets added to all the child metrics of the sensor, so both
> the group coordinator and share coordinator metrics end up adding together
> and have identical values.
> We can fix this by ensuring that {{GroupCoordinatorRuntimeMetrics}} and
> {{ShareCoordinatorRuntimeMetrics}} use different {{Sensors}}.
