Using Opentracing and uber's Jaeger client is awesome. It's easy to implement, and Jaeger provides multiple different mechanisms for sampling traces (always on, guaranteed throughput etc.).

It's awesome to be able to see a UI giving you diagrams like this: https://www.dropbox.com/s/b2uhx77urpnuk9g/Screenshot%202017-... for your API.

Definitely would recommend - it beats old-school log tracing.
