Elek, Marton commented on HDDS-910:
-----------------------------------
Thanks [~bharatviswa] the patch. I have no problem with it, but can you please
help me to understand why is it required? I think the metrics worked without
implementing MetricsSource with all the other Ozone specific metrics class.
Did you use some specific MetricsSink?
Did you miss some metrics value from the JMX interface?
What was the original problem and how can I reproduce it?
(I am just curious and would like to learn more about the hadoop metrics...)

> Implement MetricsSource interface, so that external metrics can collect the
> OMMetrics.
>
> From *MetricsSource.java:*
> It registers with \{@link MetricsSystem}, which periodically polls it to
> collect \{@link MetricsRecord} and passes it to \{@link MetricsSink}.
