[flow-tools] RE: bandwidth monitoring for subnets

[ctc]

Please forgive the last e-mail. 'twas a slip of the keyboard.

I'm trying to monitor bandwidth for subnets with flow-tools.
I've got it currently collecting flows. I'm having a little difficulty 
figuring out how to generate reports. I'd like to get bandwidth totals for 
specific networks (eg.10.1.1.*) incoming and outgoing (eg. 10.1.1.* --> 
*.*.*.* and *.*.*.* --> 10.1.1.*) . I'd like to get this by month. Is there 
any specific documentation I could look up that would help me with this?

Thanks,
Corban
