Proposition 1:
Create a separate file that specify the unit for each meters, to be provided by each meter's writer at code time.
Proposition 2:
Meter to provide this information within each event, which would be simpler to implement, but waste a bit more space.
How much is wasted: imagine a 1 KB event, an unit would represent around 10 bytes, so it's 1%.
Also, storing units allows the unit to change in the time without messing with old events records.
CW need the unit information also. CW has different unit type as ceilometer's metering in some event. We also need consider that possibly different hypervisor has different unit returned. I'd suggest to add the unit into counter. -- yjiang5
