You’re welcome

PRTG Network Monitor installed on a spare mini PC or laptop, can monitor everything you’d ever want and more.

Smokeping works great check multiple endpoints https://oss.oetiker.ch/smokeping/

https://www.epanorama.net/blog/2017/07/16/probing-ethernet-cable-with-an-oscilloscope/

This article talks about measuring 10 Mbit/s (10Base-T) and 100 Mbit/s (100Base-TX) twisted pair Ethernet signals. Those standards use two wire pairs for the communications and use differential signaling.
