How it works

Configuration Example (Minimal API)

var builder = WebApplication.CreateBuilder(args);

builder.Logging.ClearProviders();
builder.Logging.AddConsole(options =>
{
    options.IncludeScopes = true;
    options.TimestampFormat = "yyyy-MM-ddTHH:mm:ss.fffZ ";
});

builder.Services.AddOpenTelemetry()
    .WithTracing(trace => trace
        .AddAspNetCoreInstrumentation()
        .AddHttpClientInstrumentation()
        .AddSource("Orders"))
    .WithMetrics(metrics => metrics
        .AddRuntimeInstrumentation())
    .WithLogging(logging => logging
        .AddConsoleExporter());

var app = builder.Build();

app.MapPost("/orders", async (
    ILogger<Program> logger,
    HttpContext context) =>
{
    using var scope = logger.BeginScope(new
    {
        CorrelationId = context.TraceIdentifier,
        Tenant = context.Request.Headers["X-Tenant"].FirstOrDefault() ?? "unknown"
    });

    logger.LogInformation("Received order request");

    // Simulate work
    await Task.Delay(10);

    logger.LogInformation("Order accepted at {AcceptedAt}", DateTimeOffset.UtcNow);
    return Results.Accepted();
});

app.Run();
