This request doesn't make much sense to me. If you want bytes/sec, why aren't you sending that data to Graphite?
I think a much better solution would be to send the actual data you want to graph to graphite, rather than trying to calculate it after the fact. -Nick On Feb 21, 2012, at 3:55 AM, redbaron <[email protected]> wrote: > Question #148743 on Graphite changed: > https://answers.launchpad.net/graphite/+question/148743 > > redbaron posted a new comment: > Question doesnt look answered to me.
