Hey guys, cc: harlowja, DinaBelova, boris-42 I saw a lot of great work in OSProfiler. I see that "Trace every N request configuration (not done yet)". [1] Both Zipkin [2] and OpenTracing [3] have this feature. OSProfiler aim to be a small library --> May this feature make any overhead? Do you guys have any idea how to implement this?
