    [ https://issues.apache.org/jira/browse/HBASE-15519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17163919#comment-17163919 ] 

Michael Stack commented on HBASE-15519:
---------------------------------------

[~ankit@apache.org] There are two users accessing my system but I have 138 instances of a thread whose name is always 'lossy-count-0". This seems like a mistake? [~xucang] ... flagging you because the basis here is your work (though off by default).  Thanks.

> Per-user metrics will be useful in multi-tenant cases where we can emit number of requests, operations, num RPCs etc at the per-user aggregate level per regionserver. We currently have throttles per user, but no way to monitor resource usage per-user. 
> Looking at these metrics, operators can adjust throttles, do capacity planning, etc per-user.
