Not really. I mean, not any more difficult than any other internal component of an application. Yes, you can't just aggregate by URL endpoint, but add opentracing and start at the top level resolver, and then start a new segment at each nested resolver. Poof - you have an extremely nuanced view of your application performance. Add in aggregate time metrics for each unique query/mutation and you'll have an even better view of what going on - far better than if you were simply looking at API endpoint timings in the first place.
