Enis Soztutar commented on HBASE-15518:
---------------------------------------
I've put this in a cluster to test. There is an issue it seems:
{code}
{
"name" : "Hadoop:service=HBase,name=RegionServer,sub=Tables",
"modelerType" : "RegionServer,sub=Tables",

"numTables" : 9
}
{code}
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.
Also, look at this:
{code}
"Namespace_default_table_tsdb-tree_metric_readRequestCount" : 1849882,
{code}
However, the region metrics for this table {{tsdb-tree}} is:
{code}
"Namespace_default_table_tsdb-tree_region_8cbc7ef45755eed3206858da0d8caa3e_metric_readRequestCount"
: 0,
{code}
[~aliciashu] can you please check what is going on. Thanks.

> Project: HBase
> Issue Type: Sub-task
> Reporter: Enis Soztutar

> 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.
