Novo Nordisk C# Bifrost Exporter

The content of this library is a set of OpenTelemetry instrumentation extensions for exporting telemetry to Bifrost. This library is intended to be used in conjunction with the OpenTelemetry SDK and exporter libraries.

It is based on https://github.com/NovoNordisk-OpenSource/heimdall-templates-dotnet-microservice/blob/main/src/Heimdall.Templates.Dotnet.Microservice.Infrastructure/OpenTelemetry

Example

Log Exporter

Here is an example with a dummy configuration that will export open telemetry logs to Bifrost using a service principal.

builder.Logging.AddOpenTelemetry(options =>
{
    options.AddBifrostExporter(
       bifrostEndpoint: "https://your.bifrost.endpoint/otlp/http/v1",
       bifrostEnvironmentId: "d9a8719a-8bc2-4829-a078-231df13fd125",
       identityOptions: new MicrosoftIdentityOptions
           {
               Instance = "https://login.microsoftonline.com/",
               ClientId = "8be5cb8b-3a8d-47bf-9b70-660963b311ef",
               ClientSecret = "ThisIsYourClientSecret",
               TenantId = "c39886aa-7273-4937-9cad-53b86940713f")
           });
});

The BifrostOptions can also be used in case you want to use the same configuration for both logs, traces and metrics.

var bifrostOptions = new BifrostOptions
{
    bifrostEndpoint: "https://your.bifrost.endpoint/otlp/http/v1",
    bifrostEnvironmentId: "d9a8719a-8bc2-4829-a078-231df13fd125",
    identityOptions: new MicrosoftIdentityOptions
        {
            Instance = "https://login.microsoftonline.com/",
            ClientId = "8be5cb8b-3a8d-47bf-9b70-660963b311ef",
            ClientSecret = "ThisIsYourClientSecret",
            TenantId = "c39886aa-7273-4937-9cad-53b86940713f")
        });    
};

builder.Logging.AddOpenTelemetry(options =>
{
    options.AddBifrostExporter(bifrostOptions);
});

builder.Services.AddOpenTelemetry()
    .WithTracing(tracing =>
    {
        tracing.AddBifrostExporter(bifrostOptions);
    }
    .WithMetrics(metrics =>
    {
        metrics.AddBifrostExporter(bifrostOptions);
    };

How to Contribute

Branching Strategy

Trunk based branching strategy is used. New features are added by creating feature branches that are merged to main with a pull request. Pull requests requires the build pipeline to pass.

Versioning

The nuget package follows semver.org.

Release Procedure

These are the steps needed to create a new release:

1. Make sure the CHANGELOG.mdis up to date in tha main branch.
2. In GitHub, create a new release.
   1. The tag version should be the same as the version in the CHANGELOG.md file, prefixed with a 'v'. For example v1.2.3.
   2. The release title should be the version number. Fx 1.2.3. The release title is used as the version number in the nuget package.
3. The release pipeline will now create a new nuget package and publish it to nuget.org.

To build and publish the nuget package manually, do the following:

1. Build and test the solution dotnet build and dotnet test
2. Package the nuget package with the right version: dotnet pack NovoNordisk.OpenTelemetry.Exporter.Bifrost -c Release /p:PackageVersion=[SEMVER. Fx 1.2.3]

TODO

• We could probably use BifrostOptions in the private methods of BifrostExporter and make the arguments simpler.
• Add tests
