How to read data?

Hello,

I have download Netflow Analyzer. Now I have made config changes on two routers - Site A Router A (two interfaces - FE0/0 & S0/0) and Site B Router B (two interfaces - FE0/0 & S0/0). Both these routers are Cisco 1760. Connected by Point-Point FULL T1.
I have setup ip flow-export source FastEthernet0/0.

Now, how do I get Bandwidth usuage from the data collected?

Thanks for the help.

Regards,
Krishna
