The day after your new feature goes live, someone will want to know how well it’s working (or not). They don’t just mean “are there any exceptions in the logs”. They mean “how are people using it, if at all?”
Hopefully, you had thought about unspecified requirements and so you already implemented something that they can see. It doesn’t even have to be super heavyweight. I’ve seen good stuff done using something sophisticated like Heap Analytics, and also seen people be able to get actionable insights from something as simple as Google Analytics.
Whatever you choose to do, make sure that there is an easy way for a non-developer to dig around the stats, and ideally download some raw data to play around with offline.
Just be sure to track everything.
