[mrtg] AW: Re: monitoring bandwidth per protocol

[Oliver Ziltener]

Hello
NBAR is done in software, take care of this impact on your router/switch
Netflow is based on the cef technology and is most done in hardware, but
the configuration is not so easy.

Best regards
Oliver

So, between the two, Netflow & NBAR, whch is better? I suspect there's
advantages and disadvantages to each...

yeah Zeeshan is right you can use ip nbar.

if your router did not support ip nbar then run cache flow on required
interface and get statistics via netflow or you can write your own
expect script  to get statistics from router. I'm sure you can find tool
or script via search on net that can be use to get cache flow
statistics.
Rule of thumb if you have data u can generate graph :)
