[mrtg] graph over 120MB

[Steve Shipway]

This is an old problem, already in the FAQ.

If you want to graph speeds of over 120Mbps, you MUST use SNMPv2 and the 64bit counters, as the standard 32bit counters will roll over within the standard 5min polling window.

Add --snmp-options=:::::2 to the beginning of your cfgmaker command line options.

It would probably make sense for cfgmaker to probe a device for SNMPv2 and 64bit counters and use them by default without having to be prompted, but it's an old program that was originally written before GigE appeared.

I'm having a similar issue.  Trying to graph 10Gig and GigE
links.  Getting some nice graphs and all, but they never go
over 120M even though the one link in question was maxing out
at 1 Gig when looking at the manufacturers management software.

Used the following:

cfgmaker --global 'WorkDir: /var/www/mrtg' --output /etc/mrtg/mrtg.cfg public at localhost
