Hope this isnt a redundant question : Cisco IOS Netflow analysis mechanisms?

["Drew Weaver" <drew.weaver () thenap com>]

        We're looking for a method of actively monitoring certain
metrics on our network via software or a somewhat inexpensive hardware
solution (those metrics being which AS numbers are the highest
destinations for our network) and information like that which will help
us with capacity planning. We are looking for suggestions if anyone has
any real-world knowledge of anything that would tell us for example:

8% of our traffic is destined to AS 2828 (XO communications) etc.

Data such as that,

Thanks.
