[mrtg] The Math

Yes, I'm new to MRTG. And I don't understand the math.

100Mbps interface

snmpd.conf on (Linux) box shows:

## specify type and speed of interfaces:
## if the last char is an asterisk, any suffix will match.
## (feel free to add more)
interface:      lo*     24      20000000
interface:      dummy*   1      10000000
interface:      eth*     6      10000000

./cfgmaker creates MaxBytes[myserver.com.2]: 1250000. Since I know this is
a 100Mbps interface, I set my.cfg as:

Target[myserver.com.2]: 2:boogers at myserver.com
MaxBytes[myserver.com.2]: 12500000
kilo[myserver.com.2]: 1024
Title[myserver.com.2]: myserver.com: eth0

I have toggled:

Options[myserver.com.2]: absolute


Options[myserver.com.2]: gauge

No matter what I do, the math just don't work. MRTG reports (default)
values as kB/s although I see data moving at rates in mB/s. In other words,
data transfers which are observed at 4mB/s are plotted at 800 kB/s
(approximate values).

What am I missing?? Thanks for any info!!
