---------------------------------
Summary: 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
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}}.
