Subject [jira] [Created] (HBASE-19285) Add per-table latency histograms
Date Thu, 16 Nov 2017 16:28:00 GMT
Josh Elser created HBASE-19285:
----------------------------------

             Summary: Add per-table latency histograms
                 Key: HBASE-19285
                 URL: https://issues.apache.org/jira/browse/HBASE-19285
             Project: HBase
          Issue Type: Bug
          Components: metrics
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Critical
             Fix For: 2.0.0, 1.4.0, 1.3.3


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.
