Alicia Ying Shu commented on HBASE-15518:
-----------------------------------------
[~enis] Regarding to "Something wrong with the aggregation for table names
"usertable" and "usertable-empty". They are showing the same values, versus
only "usertable" should be having read requests." The problem is not from my
patch, the numbers came from Region metrics data. It is an existing issue.
> Add Per-Table metrics back

> We used to have per-table metrics, but it was removed in some restructuring.
> We have per-region metrics, and per-regionserver metrics, but nothing in
> between.
> For majority of users, per-region is too granular, they are mostly interested
> in table level aggregates. This is especially useful in multi-tenant cases
> where a table's disk usage, number of requests, etc can be made much more
> visible.
> In this jira, we'll add the basic infrastructure to add a single (or a few)
> per-table metrics. Than we can improve on that by adding remaining metrics
> from the region server level.
> The plan is to NOT aggregate per-table metrics at master for now. Just
> aggregation of per-region metrics at the per-table level for every
> regionserver.
