[Tobias Oetiker]

Yesterday you sent me mail regarding Re: [rrd-users] MRTG to RRD XML file:

*> So using the MRTG format and the RRD format from log2rrd I would do

*> 
*> 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?

you should not take this aproach ... relying on the line count will fail ... 

you need to write a little program which integrates (math) the space under the 4
curves described by the values in the *.log file and then use this data to
calculate (math) the values which go into the different RRAs ...
