This sounds like a confusion between the units of measurement, and sample resolution.
Almost all of Ganglias metrics are measured in units-per-second. The sample rate, and the resolution stored, is what we're talking about when we're saying 15s. The OP was, AFAICT, concerned about the units, not the sample resolution. -- ReC On Fri, Apr 1, 2011 at 9:02 AM, Alex Dean <a...@crackpot.org> wrote: > On Apr 1, 2011, at 10:44 AM, Vladimir Vuksan wrote: > >> >> You have to do the work then.
