Bandwith monitoring for two isp(bsnl & Airtel)

[vijaya kumar s]

Hi,
I have two bb from bsnl and airtel. I have to monitor BSNL for limit of 8gb after that speed reduces to 256 for unlimited. Airtel is also similar..
I am manually checking in the bsnl portal and monitoring its usage for important downloads at higher speed and skype etc.
Is there any bandwidth meter which i can use to monitor download from 2 isps..(generally the bandwith meter monitors downloads from nw card, wifi,etc.) Now i am using shaplus bandwith meter which is good, but its gives total download from both isps..
any help in this regard..??

Thanx, networx is good, but can monitor any one isp at a time or i can select both mac address of gateway to monitor both. but report does not come separately for each isp. I need to know how much i have used on a/c of both isps ( airtel and bsnl).
As an alternate I intend to monitor only bsnl in networks and total in other shaplus bandwidth monitor.
if any one knows a better way to do this, pl help..
