Today you sent me mail regarding [rrd-users] Re: MRTG to RRD XML file:
*> make sure to use GAUGE datasource types.
*> make sure to use a start time that is about 800 days ago.
*> MRTG stores 2 datasources
*> MRTG stores (approx.):
*> 600 times 5 minute samples, time x to x+50h
*> 600 times 30 minute samples, time x+50h to x+14d2h
*> 600 times 2 hour samples, time x+14d2h to x+64d2h
*> 732 times 1 day samples. time x+64d2h to x+796d2h
*> RRAs will always be from the beginning (unlike MRTG) so if you do
*> not want to loose any data, you need to create your RRAs larger than
*> 600 rows !
*> - Copy this database
I actually think this approach would require you to have one RRD with one
AVERAGE type RRAs and another one with MAX type RRAs ... otherwhise the MAX
stuff will not be kept the way it was ...
