As I always do, I stopped crying, read the documentation of MRTG, and then
read it again and again and again and again and ... guess what I found:
1. In the /etc/mrtg.cfg, following the sample provided, I defined a
MaxBytes value based on 256kbps / 8 * 1000. This would have been correct
EXCEPT that as evident I exceed this rating. I found out about the AbsMax
setting and set this to the theoretical maximum of the LAN card.
2. I prefer using 1024 instead of 1000 (so instead of Kilobytes I'm
technically reporting Kibibytes) so I use a MaxBytes setting of 32768 and
a AbsMax setting of 1310720 and a kilo setting of 1024.
[OFF-TOPIC: What IS the telco standard when converting Kbps -> bps? KBps
-> Bps will follow easily from this. Ang gulo kasi nung 1000 vs 1024 eh.]
3. I retain all my other settings.
Now my MRTG reports are pretty close to the kbytes/sec values of
iptraf:
Current In: 41.9 kB/s (130.8%)
Current Out: 1031.0 B/s (3.1%)
Whee!!!
What's more, the graphs are cute. I get a horizontal line with my
theoretical maximum, and from there the graph goes up to show me how good
the transfer's going. :)
[BTW Ian: if your perl script can do away with snmp and can still achieve
similar results with mrtg then my offer holds to exchange any single CD
you want _at cost_ (not free, sorry) for that.]
