mrtg and tweaking hobbitgraph.cfg

[Ariel Sandberg]

I'd like to tweak the [mrtg] section in hobbitgraph.cfg
"@RRDIDX@"  "@RRDPARAM@"  is there one for the time units it measures against
ie wether it is 48 hour 12 day, 48 day or 576 Day measurement of time

I want to be able to calculate the total bandwidth for the alotted
period of time for my mrtg interfaces.  I've done this crude
modification, to hobbitgraph.cfg, for now but was wondering if there
was a better way get the bandwidth IN/OUT to reflect the current graph
and its length of time snapshot

Thanx for your input, also if you see any mistakes in my calculations
please let me know.
Cheers,
Ariel
