Internet Speed Monitor

One of the most popular internet speed test sites is https://www.speedtest.net/ by Ookla.  They also make available executables that run on your local computer and connect to the Ookla servers to perform a speed test ( https://www.speedtest.net/apps/cli ).

The Internet Speed Monitor utility uses this command line program to repeatedly run the Ookla program to monitor the internet speed you are getting from your ISP.

Below is a sample of the Internet Speed Monitor display.  

You can see that the download speed is averaging about 70Mbps, the upload speed about 50 Mbps, and the latency around 20ms.  It looks like the internet connection was down for about an hour between 8pm and 9pm on 10/11.
