I think you would need something that tracks relevant per cable metrics over time to see if it is degrading.
That one just says yes/no, but maybe yes/no starts to flicker around its end of life?
wiggle the cables around to see if and when any of the lights flicker, indicating a bad or broken connection. i've found a few bad cables that would intermittently fail.
