[rrd-users] Re: MRTG to RRD XML file

[Dale Hege]

So using the MRTG format and the RRD format from log2rrd I would do
something like this?

RRA:AVERAGE:0.5:1:600         is lines 3-603 section 2 & 3
RRA:MAX:0.5:1:600             is lines 3-603 section 4 & 5
RRA:AVERAGE:0.5:6:600         is lines 603-1203 section 2 & 3
RRA:MAX:0.5:6:600             is lines 603-1203 section 4 & 5
RRA:AVERAGE:0.5:24:600        is lines 1203-1803 section 2 & 3
RRA:MAX:0.5:24:600            is lines 1203-1803 section 4 & 5
RRA:AVERAGE:0.5:288:732       is lines 1803-end section 2 & 3
RRA:MAX:0.5:288:732           is lines 1803-end section 4 & 5

For which values in the xml should I calculate?
