Hi Dave, yes, if you define your first rra definition with 40320 Datapoints, you will be able to look back 1 week in 15sec intervall.
here an example of my configuration with the possibility to look backward 2 days (with an accuracy of 15sec) *RRAs -hour- -day- -week- -mounth- -year-* RRAs "RRA:AVERAGE:0.5:1:11520" "RRA:AVERAGE:0.5:24:2880" "RRA:AVERAGE:0.5:168:2016" "RRA:AVERAGE:0.5:672:2928" "RRA:AVERAGE:0.5:5760:8760" If i try to have a look at a specific hour after 2 days, the graphs will "rugged" greets Ron Cademair schrieb: > Ron, > > Thank you very much for confirming my suspicion.
