Elliott Clark commented on HBASE-5786:
--------------------------------------
You're absolutely right about it being Zipfan, I was just trying to discuss the
upper bound on error without having to do the math for confidence with
different distributions. Seems like another issue should be filed to implement
different sampling so that we don't de-rail this one too much.
> Implement histogram metrics for flush and compaction latencies and sizes.

> Key: HBASE-5786
> URL: https://issues.apache.org/jira/browse/HBASE-5786
> Project: HBase
> Issue Type: New Feature
> Components: metrics, regionserver
> Affects Versions: 0.92.2, 0.94.0, 0.96.0
> Reporter: Jonathan Hsieh
>
> Average time for region operations doesn't really tell a useful story when
> that help diagnose anomalous conditions.
> It would be extremely useful to add histogramming metrics similar to
> HBASE-5533 for region operations like flush, compaction and splitting. The
> probably should be forward biased at a much coarser granularity however
> (maybe decay every day?)
