Hi Dougdog

I have used PRTG in the past. It is usefull even in "trail" mode. Just remember that it is based on ping response times and if your network QOS setup does not allocate priority to the required traffic it might end up with inaccurate info / reports when the line is under pressure.

*** Additional info***
I have experienced a similar problem in the past with speeds on MPLS. You might end up with a scenario where you will need to do a tracert from the site to a different location. You might notice that the speed on the line from your location runs correctly until it hits the ISP "cloud/network". odds are it goes wrong within their config.

Ixia Qcheck using the TCP throughput test with 1000kBytes packet size will generally show the maximum you can get through a network path. it requires the application to be running on a PC at each site. I use RDP to control the remote one.

If you want ip to ip ,then you need to set up jperf.

One end is set up as client,the other is set up as server.

The nitro was to test for issues for infrastructure and isp bottlenecks.
