--------------------------------------------
Summary: AppInfoParser should only use metrics API and should not
register JMX mbeans directly
Key: KAFKA-6011
URL: https://issues.apache.org/jira/browse/KAFKA-6011
Project: Kafka
Issue Type: Bug
Components: metrics
Reporter: Ewen Cheslack-Postava
Priority: Minor
AppInfoParser collects info about the app ID, version, and commit ID and logs
them + exposes corresponding metrics. For some reason we ended up with the app
ID metric being registered directly to JMX while the version and commit ID use
the metrics API. This means the app ID would not be accessible to custom
metrics reporter.
This isn't a huge loss as this is probably a rarely used metric, but we should
really only be using the metrics API. Only using the metrics API would also
reduce and centralize the places we need to do name mangling to handle
characters that might not be valid for metrics.
