EWMA vs mean unit of measure inconsistency in meters #74
Description
Meters can be used for a number of things, but consider this example:
We want to measure the number of events per second, where an event is folsom_metrics:notify(Name, 1).
So we do folsom_metrics:get_metric_value(Name). What we get in response is
[{count,...}, {one, ...}, {five, ...}, {fifteen, ...}, {day, ...}, {mean, ...}, {acceleration, ...}]
where one, five, fifteen and day are measured in events per second, but mean is measured in events per _micro_ second. Furthermore, acceleration is measured in events per second squared.
I believe it would be more consistent if mean were measured in events per second as well.
Suggested fix: divide this value by 1000000. May need to do something similar for meter reader as well.
