Subject [jira] [Commented] (HADOOP-12561) Add documentation about metrics system
Date Sat, 07 Nov 2015 11:11:10 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14995161#comment-14995161
] 

Steve Loughran commented on HADOOP-12561:
-----------------------------------------

It's mostly covered in the javadocs, stuff a metrics.md shouldn't duplicate. Whatever is added,
it should just cross-ref to the current javadocs for the low-level bits

> Add documentation about metrics system

> Though there is [reference of metric items|https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/Metrics.html],
we have no documentation about metrics system and configuration. Adding concise documentation
about metrics system would help users, admins and developers.
