So, if I want the percentage of collisions, I could use the formula:
Collisions/FrameCount*100

I tried with:
Target[collch]:
1.3.6.1.2.1.16.1.1.1.13.port&1.3.6.1.2.1.16.1.1.1.13.port:public at x.x.x.x/1.3.6.1.2.1.16.1.1.1.5.port&1.3.6.1.2.1.16.1.1.1.5.port:public at x.x.x.x*100
AbsMax[collch]: 100
MaxBytes[collch]: 100
Options[collch]: nopercent
(I don't think the perhour option would change something there)


I doesn't work. What is the exact syntax for calculating percentages
with MRTG?
(yes, it's my first calculation attempt :-)
