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 occur
  • exceptions recorded on traces, client disconnects ignored
  • inject trace id to http requests
  • health checks (excluded from tracing)
  • best practices from aspire
    • servicediscovery
    • http resilience handler

Initialization in ASP.NET Core

builder.AddObservability();

builder.Services.Configure<ObservabilityOptions>(options =>
{
    options.TraceIdHeader = "x-trace-id";
    options.Augment = (context, tags) =>
    {
        tags.Add("TenantId", "extract from http context");
        return ValueTask.CompletedTask;
    };
});

// required - register early, so exceptions from later middleware are enriched and handled
app.UseObservability();

// optional - /health and /alive are anonymous, consider mapping them only in development or on an internal port
app.MapObservabilityHealthChecks();

app.UseAuthorization();

app.MapControllers();
app.Run();

More Instrumentation

builder.AddObservability(configureTracing: tracer =>
{
    tracer.AddEntityFrameworkCoreInstrumentation();
    tracer.AddRedisInstrumentation();
});
