# 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();
});
```
