Hi Adam, Our experience was that the summary RRDs were actually generated but then rarely updated. Only very occasionally would we see metrics suddenly get written to the RRD and only for a few intervals and then there would be large gaps again. Do graphs based on the RRDs you are getting in your tests look right? Regards, Nick On Fri, Nov 15, 2013 at 8:15 PM, Adam Compton <aco...@qu...>wrote: > Nicholas, I'm the person who submitted #92.
