[olug] Monitoring/graphing Ethernet port errors.

I'm trying to monitor for port errors on my Cox cable modem -- under load
I'm getting about 3-5% CRC or Framing errors on in-bound packets (Cox was
out and said they see some issues with the up-stream signal so they'll be
out tomorrow too).

I've got a Cisco switch (2900) between the switch and firewall so I can use
MRTG to graph the bandwidth, but I can't seem to find a good example of
monitoring errors (ifInError and ifOutError).

Right now I have it setup to pull the ifInError/ifOutError data, but the
graphing is setup like it's pulling bandwidth so the scales and graphs don't
really provide a usable chart...

Anyone have a sample bit of mrtg.conf I can use?

Or has the world moved on to Cacti, or Cricket, or Zabbix, or...?
