Subject [jira] [Updated] (HDFS-11468) Ozone: SCM: Add Node Metrics for SCM

Yiqun Lin updated HDFS-11468:
    Attachment: HDFS-11468-HDFS-7240.003.patch

Thanks for the review, [~cheersyang].
For your fist comment, I think {{lastConainerReportTotalSize}} is too long. Since metric is
the data of aggregated statistics. I'd like to update this as {{ConainerSize}}. This will
look simplify and also good understanding.

bq. second, as we already have SCMMXBean, can we merge these metrics to that class?
I don't agree with this. There will be some more type scm metrics added into SCMMetrics in
the future. Why we merge these metrics into that class? SCMMXBean is just the JMX  interface
for exposing scm information.

Attach  the update for addressing first comment.
