The agent provides the outer-most Span; Pedestal's request-tracing interceptor adds the inner Span; this means we get much better information about the time spent outside of Pedestal.

For example, when streaming a long response, Pedestal will have closed its Span while the response is still sent back down but Jetty is still working on it and I believe that time will be reflected in the outer span, at the end.

Early days yet...

Nice!! Looks much better than the default jetty 8 spans I’m getting. Those are all under GET /** for some reason.

This is with Jetty 11. The agent seems to provide a span named after the method, and the interceptor creates a span named with the method and route path.

Very exciting!

Can’t wait to try it out 🙂
