# 3-Line OpenTelemetry ASP.NET Core Integration

- trace id in response header

- sends logs, metrics and traces to opentelemetry collector

- enrichment/augmentation of logs and traces even when exceptions occurr

- inject trace id to http requests

- health checks

- best practices from aspire

  - servicediscovery

  - http resilience handler

## Initialization in ASP.NET Core

```csharp

builder.AddObservability();

builder.Services.Configure(options =>

{

    options.TraceIdHeader = "x-trace-id";

    options.Augment = (context, tags) =>

    {

        tags.Add("TenantId", "extrakt from http context");

        return ValueTask.CompletedTask;

    };

});

```

```csharp

// optional

app.MapObservabilityHealthChecks();

app.UseAuthorization();

// required

app.UseObservability();

app.MapControllers();

app.Run();

```

## More Instrumentation

```csharp

builder.AddObservability(configureTracing: tracer =>

{

    tracer.AddEntityFrameworkCoreInstrumentation();

    tracer.AddRedisInstrumentation();

});

```
