Tracing
|
|
=======
|
|
|
|
This page details how to perform distributed tracing with Ocelot. At the moment we only support Butterfly but other tracers might just work without
|
|
anything Ocelot specific.
|
|
|
|
Butterfly
|
|
^^^^^^^^^
|
|
|
|
Ocelot providers tracing functionality from the excellent `Butterfly <https://github.com/liuhaoyang/butterfly>`_ project. The code for the Ocelot integration
|
|
can be found `here <https://github.com/ThreeMammals/Ocelot.Tracing.Butterfly>`_.
|
|
|
|
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.
|
|
|
|
``Install-Package Ocelot.Tracing.Butterfly``
|
|
|
|
In your ConfigureServices method
|
|
|
|
.. code-block:: csharp
|
|
|
|
services
|
|
.AddOcelot()
|
|
// this comes from Ocelot.Tracing.Butterfly package
|
|
.AddButterfly(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..
|
|
|
|
.. code-block:: json
|
|
|
|
"HttpHandlerOptions": {
|
|
"UseTracing": true
|
|
},
|
|
|
|
Ocelot will now send tracing information to Butterfly when this ReRoute is called.
