I woke up to an automated email saying that we'd blown our 40Gb xtra
ADSL traffic quota for the month and were now paying 2c / MB etc.
Checking our usage meter it showed we'd supposedly downloaded 9.5Gb
yesterday.
I don't think I've managed to downloaded 9Gb over an entire week in the
past let alone in one day, so I will be submitting a complaint.
Just wondering if anyone else on Xtra broadband had a massive "usage"
hike yesterday?
Hmmm... interesting - broadband usage meter is now offline while a
problem is being fixed:
"Some customers may be experiencing problems with their usage meter. Our
technicians are currently working on this problem. At this stage our
representatives are unable to provide any additional information. We
apologise for any inconvenience and thank you for your patience."
Yes - their readings are screwey for the last day or so.
Your best protection is to do something to record your traffic.
I recommend probing your DSL router via SNMP and graphing the output in
cacti. At least that gives ammunition in the event of a disagreement.

pfsense is capable of graphing its interfaces internally, but I'm not sure
if that data survives a reboot.

Aren't those rate graphs rather than total usage graphs? They may show
that particular link isn't used much, but you really need the integral
with respct to time to get total usage over a period.
I am pretty sure an rrd tool can do this too, if fed the right info.
Eyes - open them... bottom line shows 11.91 MBytes for that 3 hour
window in the top of the cacti graph
Likewise the pfsense rrd graphs show 12.6 MBytes in 10.4 out and 23.03
MBytes total in the 2 days graph.
But you are right - the graphs are of bandwidth usage. However the only
difference would be the scale and units on the vertical axis... the
graph line would look exactly the same shape.
Admittedly that probably wasn't the best interface to graph... should
have shown my internet connections like this 5 day window.....
