[plug] Traffic monitoring.

[Gavin Tweedie]

Heya guys,
This is slightly off topic, but anyways...

I'm seeking a good linux based solution to monitor interfaces on (mainly)
cisco routers in terms of bytes/octets in and out.
It would be best if its perl based and even better if it can display
results to a webpage and would be VERY nice if you can specify time
periods to be shown or to just show 24hr periods for several days etc.

For the ISP kinda people, I basically want something like what you recieve
from TIA/Paradox/Optus each week/month/whatever which shows you your usage
which arrives in your email.

If anyone has any recommendations (of free/gnu) software or suggestions
I'd like to hear them

Ta.

Gavin
