-----------------------------------------

             Summary: Add OpenTracing support
                 Key: DISPATCH-1088
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1088
             Project: Qpid Dispatch
          Issue Type: New Feature
            Reporter: Carsten Lohmann


In order to get an overview of the lifetime of a message going through different messaging components, it would be good to have support for distributed tracing in the dispatch router.
 The [OpenTracing|http://opentracing.io/] standard defines an API for this, facilitating the use of different (OpenTracing-compatible) tracing systems (e.g. [Jaeger|https://jaegertracing.io/]).

This will mean identifying the different steps of the message processing inside the router and creating/finishing corresponding (child-)_Span_s for it (see [OpenTracing semantic spec|https://github.com/opentracing/specification/blob/master/specification.md]).

As for the implementation, there is an [OpenTracing API for C++|https://github.com/opentracing/opentracing-cpp].

Some more pointers:
 - [Example for loading the tracer library dynamically|https://github.com/opentracing/opentracing-cpp/blob/master/example/dynamic_load/dynamic_load-example.cpp] (corresponding [PR|https://github.com/opentracing/opentracing-cpp/pull/45])
 This approach is supported by Jaeger now as well.
