Hi Guys,
Its been a long time since I made a post here. Anyway, I was working on this great tool that I thought I want to share to the community. I installed it in my linux box to monitor the traffic of all my routers. It also shows up/down status of the interface. Take note that this tool is free from linux community. It has a windows version as well but i find it hard to install in windows. you can get info on this site: www.cacti.net
Enjoy!!!
