[tlug] MRTG question

["Jean-Christian Imbeault" <jean_christian@example.com>]

I feel dumb for asking but ... I've got a small bytes to bits problem with 
MRTG.

I've stoped using SNMP to give out data transfer numbers to MRTG and instead 
am using a little perl script someone wrote to fetch the data directly from 
/proc/net/dev as suggested by Tobias.

Everything works but the numbers MRTG puts out seem to be confused as to 
wether they are bits or bytes.

I have a 100Mbps line and right now MRTG is giving out these numbers as 
outgoing bandwidth usage:

Max  Out: 6844.3 kB/s (6.8%) Average  Out: 4802.8 kB/s (4.8%) Current  Out: 
6844.3 kB/s (6.8%)

6844.3 kB/s is about 6.8 MB/s ...my line is 100 Mbps (or 12.5 MBps) ... 
there's no way that I am using >50% of the bandwidth ... (Though the 
*percentages* given out are about right, but not the raw numbers).

Can someone help me figure out what I am doing wrong? Is my arithmetic wrong 
or my MRTG config file? Or the script that provides the numbers?

I think my MRTG config file must be off ...

If anyone can help out, here's what my config file looks like:

MaxBytes[eth0]: 12500000
AbsMax[eth0]: 12500000
Options[eth0]: bits, growright, transparent,dorelpercent
Target[eth0]: `/usr/local/mrtg-2/mrtg-eth.pl -d eth0`
YLegend[eth0]: Bytes/s
ShortLegend[eth0]: B/s
Legend1[eth0]: Incoming Traffic
Legend2[eth0]: Outgoing Traffic
Legend3[eth0]: Maximum Incoming Traffic
Legend4[eth0]: Maximum Outgoing Traffic
LegendI[eth0]:  In:
LegendO[eth0]:  Out:
WithPeak[eth0]: ymwd
YTics[eth0]: 4

Thanks,

Jc
