Ocelot providers tracing functionality from the excellent Butterfly project.

In order to use the tracing please read the Butterfly documentation.

In ocelot you need to do the following if you wish to trace a ReRoute.

In your ConfigureServices method

    .AddOpenTracing(option =>
        //this is the url that the butterfly collector server is running on...
        option.CollectorUrl = "http://localhost:9618";
        option.Service = "Ocelot";

Then in your ocelot.json add the following to the ReRoute you want to trace..

"HttpHandlerOptions": {
      "UseTracing": true

Ocelot will now send tracing information to Butterfly when this ReRoute is called.
