Jamie Grier commented on FLINK-1502:
------------------------------------
[~eastcirclek] You shouldn't need to do this with counters. Typically you just
want to report the value of the counter as is to the metrics system. The
metrics system (e.g. Graphite or Ganglia) should have built-in tools for
turning counters into other types of graphs. For example, what you really want
here is a "rate", how many GC invocations per second for example (1st
derivative of counter). Ganglia and any decent metrics tools should already
have this function builtin. I think we should just report the raw counters.
> Expose metrics to graphite, ganglia and JMX.
