I am looking for suggestions on how to best monitor traffic between our companies two sites. We have a T1 line running between the two and are trying to find a solution that will help us monitor and analyze the traffic that is going back and forth at any given time. I am familiar with Ethereal however just capturing the packets isn't exactly what I had in mind. We would like to have something that could show us the utilizlation of the line as well as what type of traffic is going back and forth. It's something we would like to be able to keep running at all times. Any ideas would be welcome!
