Jamie Grier commented on FLINK-1502:
------------------------------------
[~eastcirclek] Yes, I believe it does. It's implicit in the metric type that
get's reported to Ganglia. I believe what we want is Slope.POSITIVE for
counters. I imagine the Dropwizard metrics library would already do this
correctly for metrics with type Counter (as opposed to gauge) -- but maybe not.
See here:

Also, is there no query language in Ganglia when building a graph that allows
you graph the rate of change rather than the actual metric? I'm not too
familiar with Ganglia.
> Expose metrics to graphite, ganglia and JMX.
