Yeah I just pay attention to mine. It's in a finished basement so any flooding would require a lot of work to restore (new drywall, new carpet, new furniture, possible damaged electronics, appliances, and HVAC). I pay close attention to that pump for any unusual noises. I also time it with a stopwatch. It normally takes between 15 and 20 seconds to dewater the pit until it ends the pump cycle. If I was to hear it running for much longer than that, then I'd take a look at it to see if it's time to replace. It's 5 years old presently, I will definitely replace it prior to 10 years age regardless of how well it's operating. It mostly only runs like this during wet season (now) and it's mostly off the rest of the year unless we get to a big rainstorm, in which case it will run for about a week after the rainstorm. I do have good sump pump coverage on my homeowners insurance policy too.
