Getting Started with OpenTelemetry .NET in 5 Minutes

First, download and install the .NET Core SDK on your computer.

Create a new console application and run it:

dotnet new console --output getting-started
cd getting-started
dotnet run

You should see the following output:

Hello World!

Install the OpenTelemetry.Exporter.Console package:

dotnet add package OpenTelemetry.Exporter.Console -v 0.7.0-beta.1

Update the Program.cs file with the code from Program.cs:

Run the application again (using dotnet run) and you should see the trace output from the console.

Activity.Id:          00-8389584945550f40820b96ce1ceb9299-745239d26e408342-01
Activity.DisplayName: SayHello
Activity.Kind:        Internal
Activity.StartTime:   2020-08-12T15:59:10.4461835Z
Activity.Duration:    00:00:00.0066039
Activity.TagObjects:
    foo: 1
    bar: Hello, World!
    baz: [1, 2, 3]

Congratulations! You are now collecting traces using OpenTelemetry.

What does the above program do?

The program creates an ActivitySource which represents an OpenTelemetry Tracer. The ActivitySource instance is used to start an Activity which represents an OpenTelemetry Span. An OpenTelemetry TracerProvider is configured to subscribe to the activities from the source MyCompany.MyProduct.MyLibrary, and export it to ConsoleExporter. ConsoleExporter simply displays it on the console.
