Chris Riccomini commented on SAMZA-349:
---------------------------------------
bq. I would say that adding a reporter to your job config should not alter the
values of the metrics that are reported.
Doh, good point.
bq. Rather than resetting, how about having MetricsSnapshotReporter track the
previous value for each counter, and report the difference? That would remove
the side-effect.
Good idea.
+1 to Martin's suggestions.

> If my understanding is correct, the metrics we provide are for every 60
> seconds and all counters will be reset every 60 seconds. Current the
> MetricsSnapshotReporter seems missing this implementation. It sends out the
> metrics every 60 seconds but does not reset the counter value.
