This repository is a suppliment to my Talk around using OpenTelemetry with .NET.
It can be used as a standalone example of configuring and using OpenTelemetry with .NET, specifically demoing:
- ASP.NET Core automatic instrumentation
- HttpClient instrumentation
- Using Baggage between mulitple services
The solution required .NET 6.0 which you can download from here: Download .NET 6
From the repository root directory:
dotnet build
The solution is separated into 2 services.
This is to simulate the Endpoint that a user would interact with directly.
This is to simulate an internal backend service that is only called from the edge service.
The first thing to do is get a Jaegar instance up and running to receive the traces. This repository provides a preconfigured Jaegar instance in the form of a Docker Compose. You'll need docker installed in order for this to work.
docker-compose up -d
Next, we'll need the services to be running.
cd service1
dotnet run
in another terminal window
cd service2
dotnet run
You'll now be able to open a browser or run wget/curl for the service1 URL.
This will generate a basic single service trace with just the basic ASP.NET Core instrumentation.
This will generate a single service trace with a child span with delays so that you can see the generated spans.
This will generate a distributed trace with baggage propagation.
If you open a browser and navigate to the below URL, you can select OpenTelemetry Demo from the services dropdown, then click "Find Traces".
