Dave Brosius updated CASSANDRA-5838:
------------------------------------
Attachment: 5838.txt
Major changes are
1) MetricsRegistry is no longer static, so i added static c* class that holds
the instance
2) No more MetricName class, just strings... adjusted accordingly
3) simple api renamings value() now getValue() etc.
4) Removal of the clear() method from Histogram and ExponentialDecayingSample
now ExponentialDecayingReservoir... Not sure how to handle this. In the one
place that mattered, i just unregistered, and then reregistered new EDRs. The
other case was from a test, that seems to pass even w/o the clears, so removed.
> Upgrade metrics-core library
