[jira] [Commented] (HBASE-16549) Procedure v2 - Add new AM metrics

    [ https://issues.apache.org/jira/browse/HBASE-16549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15946256#comment-15946256 ] 

Umesh Agashe commented on HBASE-16549:
--------------------------------------

I have summarized AMv2 metric changes in the doc: https://docs.google.com/document/d/1gJsjlacYRuFCSrp8q1zNRr8oWrel339rUtdmFuV7PxE/edit?usp=sharing.

Grouping related details like batch size for remote dispatch etc should not be exposed through metrics. We can add trace() messages for profiling and debugging.

> With the new AM we can add a bunch of metrics
>  - assign/unassign time
>  - server crash time
>  - grouping related metrics? (how many batch we do, and similar?)
