      Per-RegionServer table latency histograms have been returned to HBase (after being removed due to impacting performance). These metrics are exposed via a new JMX bean "TableLatencies" with the typical naming conventions: namespace, table, and histogram component.

      Description

      HBASE-17017 removed the per-region latency histograms (e.g. Get, Put, Scan at p75, p85, etc)

      HBASE-15518 added some per-table metrics, but not the latency histograms.

      Given the previous conversations, it seems like it these per-table aggregations weren't intentionally omitted, just never re-implemented after the per-region removal. They're some really nice out-of-the-box metrics we can provide to our users/admins as long as it's not detrimental.
