Usage monitoring software

I need a utility that will allow me to determine how much internet bandwidth I'm using, and when I'm using it. I'd like actual figures, not graphs, and I'm after the numbers my ISP would see (or at least as close as possible), so it needs to work with my router (SNMP is available).

Open source is best, but I'll pay if the price is right. Linux, OS X, Windows, all fine with me.

@Stoned_SpaZZZ:

On the router isn't an option (no firmware support, no upgrade path). On a Linux router is an option, but one I'd rather explore as a last resort.

However, I know it can be done, but I'm only getting graphs out of the tool I'm using and they're no use to me. If I get desperate, I'll throw something together in PHP/MySQL, but I'd rather not have to.

@Craig321:

Will look into PRTG to see if it'll produce the reports I need.

@Craig321:

No support for Netflow. I don't think packet sniffing will be very useful given that most of the traffic on my network goes via Linux. In any event, all I really need is the totals. Looks like PRTG Traffic Grapher might be what I want.

@tolien:

As it happens, I've already got as far as getting the data into an RRD file:

If there's a more useful way of getting the data back out, that'll be great.

PS - I know about the gaps in that data - that monitoring is done from outside my network and sometimes I get time-outs doing that. Moving the monitoring local would fix that.

SNMP, packet sniffing, and Netflow (Cisco).

I've got SNMP enabled, so that'll do.

Cacti successfully installed (eventually). As well as the pretty graphs, it looks like it'll dump data to CSV which I can then import into Excel to play with.

I'll give it a day and then see if it'll tell me the information I need to know - which is how likely I am to get capped to hell and back if I move from Be to Virgin.

Thanks all.
