I'd like to have help ("indeed ?") :
- I'd like to graph the % of an interface's load, ie. the sum of the
ifInOctets & the ifOutOctets, divided by the maximum throughput
- I suceeded in summing the ifInOctets & the ifOutOctets, writing smthg like
. at a.b.c.d +
. at a.b.c.d
- I divided this by 2.000.000 (maximum througput), so writing :
. at a.b.c.d +
. at a.b.c.d / 2000000, 
and now all = zero.

should I add parenthesis before division ?
is there a more simple way to do it ?
I looked at the faq.mrtg.org, but there's nothing for 'mathematical',
neither 'operations'...
