I am looking for a simple tool that I can monitor available bandwidth on my 3 different ISPs in real time. Not what is being used, but what is available…like a speed test, but one that can show historical data. I have PRTG but that shows what is being used. I also do not want it to constant speed tests, that would take up everything I have. I know I could just as easily do a spreadsheet and fill it in. Anyone maybe have a Powershell script that would do this, do a speed test and then fill in results on a spreadsheet?
Yes, but doing a speed test while you’re using the link isn’t an accurate test, so it’s extremely difficult to be able to show bandwidth issues with anything other than a graph. If the ISP is not giving you your full bandwidth, you’ll flatline below the full bandwidth on the graph. If you are using half your link and do a speed test you will only get results for about half your link unless you drop all other traffic to do the speed test.
