Hi!
This is my RRA setup in gmetad.conf:
RRAs "RRA:AVERAGE:0.5:1:172800" \
"RRA:AVERAGE:0.5:4:525600" \
"RRA:AVERAGE:0.5:20:210240" \
"RRA:AVERAGE:0.5:40:210240"
--> I think I collect very detailed data for 172800 intervalls with 15s
each. This would equal 30 days.
As far as I understood the rrdtool docs there should be no average being
calculated for all data with this timeframe. (Just 1 piece of data should
be used for each datapoint)
But if I take a look into the Ganglia data I see some kind of mismatch
with that theory. Usually the "Max" values in the 1h, 2h and 4h graphs are
(mostly) the same (talking about a maximum within the last 60 minutes) but
if I look at the 1d graph the "Max" value as well as the graph itself show
smaller values. There is an additonal decreasement for the 1week and
1month graphs (and values).
Is there a way to make better use of our RRA setup?
Mit freundlichen Grüßen / Kind regards
Alexander Karner
