Andrew Purtell commented on HBASE-20603:
----------------------------------------
Parking a WIP patch that does what I want, but only touches hbase-metrics-api's
Histogram. I don't want to touch FastLongHistogram because it has a lot of
legacy use all over the place. We are most interested in applying the proposed
new semantics to call metrics, so will propose that change separately as an
update of call metrics to use hbase-metrics-api's Histogram, at some future
time if this is accepted.
> Histogram metrics should reset min and max

> It's weird that the bins are reset at every monitoring interval but min and
> max are tracked over the lifetime of the process. Makes it impossible to set
> alarms on max value as they'll never shut off unless the process is
> restarted. Histogram metrics should reset min and max in snapshotAndReset.
> For discussion.
