It is kind of crude and the file will be very large but it works. It will ping 1000 times and insert a timestamp then ping 1000 more times untill you use CTL-C or close the command window. your information will be in the Text.Txt file.

Ping -n 1000 127.0.0.1 >text.txt

You can't monitor bandwidth by pinging. You can install BitMeter on server (Proxy) if possible. Google BitMeter.

This is the tool that I use to monitor bandwidth and availability on my networks.

It is Free and takes just a few minutes to set up.

bandwidth is your total capacity.

Throughput is actual bandwidth taking in consideration X conditions of the line.


latency is the X conditions such as a router in the path with lower response, overheads etc.

speed is simply how fast traffic going from point A to B on available bandwidth.

your continious ping test will send ping packets to a destination and cause congestion in the line [more overhead] and not only that cause latency because the routers in the path have to process the ping packets which cause higher CPU utilization. If you ping a router enough, you can cause it to use up most of it's resources processing the ping packets.

So that does nothing for monitoring you bandwidth. If anything gives you a false reading of available bandwidth, throughput and latency as the ping packets are causing lower throughput and higher latency.
