> 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}}.
