Hello,
I can´t fin out how RRDtool "knows" which RRA to get data from if you for
example has a setup of 4 RRA:AVERAGE:s, se below, (from the RRDtool
tutorial):
Let´s say I plot a graph from "now" to -1month, does RRDtool "automatically"
use "no 3", or do i specify it somewhere?
"no 1": 600 samples of 5 minutes (2 days and 2 hours)
"no 2": 700 samples of 30 minutes (2 days and 2 hours, plus 12.5 days)
"no 3": 775 samples of 2 hours (above + 50 days)
"no 4": 797 samples of 1 day (above + 732 days, rounded up to 797)
rrdtool create myrouter.rrd \
DS:input:COUNTER:600:U:U \
DS:output:COUNTER:600:U:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797
