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
Funny you mention it. I am seeing that
exact issue even though I am not running grid of grids. About a
week we added bunch more machines and top grid __SummaryInfo__ is
now updated only occasionally ie. I may see data once an hour.
This happens even with 3.5.0 so
