Trace binding (query tree)

[mrandybu]

I have fastapi service and krakend (already use tracing). I add tracing for nginx, but in jaeger traces are not bound to each other (nginx -> krakend). Maybe I must use specific parameters?

Sound like nginx and application use different propogation http headers.

Make sure you have configured:

    # Propagate the active span context upstream, so that the trace can be
    # continued by the backend.
    # See http://opentracing.io/documentation/pages/api/cross-process-tracing.html
    opentracing_propagate_context;

Krakend with opencesus use the x-b3-traceid
Can I change trace format on nginx, or I need change code of service?

@mrandybu You can use Zipkin opentracing library. Example: https://github.com/opentracing-contrib/nginx-opentracing/blob/master/example/go/otel/nginx.conf#L26
