Bharat Viswanadham commented on HDDS-910:
-----------------------------------------

Thank You [~elek] for the info.

It helped me understand how these things work. Yes, I have also tried with file 
sink, and I am able to see metrics.

I have one question I have created HDDS-917 for exposing NodeManagerMXBean, i 
think for that we need to implement this MetricsSource interface correct? as we 
don't have any @Metrics notations.

> 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}.
