Microsoft.Extensions.AmbientMetadata.Application 9.0.0-preview.2.24157.4

Microsoft.Extensions.AmbientMetadata.Application

This flows runtime information for application-level ambient metadata such as the version, deployment ring, environment, and name. This information can be useful to enrich telemetry.

Install the package

From the command-line:

dotnet add package Microsoft.Extensions.AmbientMetadata.Application

Or directly in the C# project file:

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.AmbientMetadata.Application" Version="[CURRENTVERSION]" />
</ItemGroup>

Usage Example

Registering Services

The services can be registered using any of the following methods:

public static IHostBuilder UseApplicationMetadata(this IHostBuilder builder, string sectionName = DefaultSectionName)
public static IServiceCollection AddApplicationMetadata(this IServiceCollection services, Action<ApplicationMetadata> configure)

Configuration

When loading from configuration, the version and deployment ring metadata are read from the ambientmetadata:application section. The environment and application names are read from the IHostEnvironment.

{
  "AmbientMetadata" {
    "Application" {
      "BuildVersion": "1.0-alpha1.2346",
      "DeploymentRing": "InnerRing"
    }
  }
}

Consuming Services

The ApplicationMetadata can be injected wherever needed. For example:

public class MyClass
{
  public MyClass(IOptions<ApplicationMetadata> options) { Application = options.Value; }

  private ApplicationMetadata Application { get; }

  public void DoWork()
  {
    Log.LogEnvironment(Application.Version, Application.DeploymentRing, Application.Environment, Application.Name);
  }
}
