-------------------------------------
Summary: Factor status and system metrics out of
JobManagerMetricGroup
Key: FLINK-14299
URL: https://issues.apache.org/jira/browse/FLINK-14299
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination, Runtime / Metrics
Affects Versions: 1.10.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.10.0
At the moment, we use the {{JobManagerMetricGroup}} to not only register
{{Dispatcher}} specific metrics but also process specific metrics such as CPU,
threads, memory, etc. Due to this fact, it is not possible to close the
{{JobManagerMetricGroup}} when the life time of the {{Dispatcher}} terminates.
In order to do this, I suggest to introduce a new {{ProcessMetricGroup}} which
is used to register the process specific metrics.
In order to guarantee backwards compatibility, I suggest to use the same scope
format as {{SCOPE_NAMING_JM}} and then appending {{.Status}}.
