MRTG graphs are in bytes instead of bits 🔗 link

I started using mrtg to graph traffic over a 1 Gbps point-to-point link
to a DR site. It is currently being monitored using cricket. When
comparing the mrtg graph to the cricket graphs, the mrtg graph seems to
be in bytes/second instead of bits/second. The y-axis label says
bits/second but the values are way to small.

This is the configuration for the switch port.

## CA to AZ P2P
Directory[mrtg.ca-coresw.gi_1_1_1]: ca2az-p2p.lereta.net
Target[mrtg.ca-coresw.gi_1_1_1]: 1:user-f79b8098fe3e@xymon.invalid
Options[mrtg.ca-coresw.gi_1_1_1]: bits
Title[mrtg.ca-coresw.gi_1_1_1]: P2P to AZ
MaxBytes[mrtg.ca-coresw.gi_1_1_1]: 125000000

I haven't used mrtg in years so I may be just screwing up the
configuration.  Any help is appreciated.

Stephen, not sure what this has to do with Xymon.

I followed the instructions here:

http://xymon.sourceforge.net/xymon/help/xymon-mrtg.html

From that it looks to me like mrtg gathers the data, puts in in the rrd
file, then XYMon invokes rrdtool to create the graphs.  I was hoping
there was something I overlooked -- and someone else can see -- in the
config that would explain the difference.

Not really a big deal.  It may be better to just divorce mrtg and XYMon.
 Or I could rewrite the "broken" parts of cricket so it works on a 64
bits.  I just liked the idea of it all being in one place.

Yep, that's how I read it too.

Nothing stands out to me. However, it's been over a decade since I did
anything with MRTG.

Agreed - it's annoying having all your data in different places.

First, I would check the RRD file contents (rrdtool fetch yada yada) to see
if the numbers look like those from Cricket data. If they don't match, then
MRTG probably needs a tweak.

Also check that the RRD file shows the values as COUNTER or DERIVE (rrdtool
info).

It would seem that showgraph uses an [mrtg] section in graphs.cfg to
determine how to display network traffic. This configuration causes data
from the RRD file to be fetched, then multiplied by 8, to turn it into
bits. This all seems fine, and should produce the desired results, as long
as the RRD data is stored in bytes.
