Intropy.Telemetry.ConsoleApp 0.1.0

Intropy.Telemetry

Simple OpenTelemetry configuration for .NET applications. Hook up tracing, metrics and logging with a single method call.

Why?

Setting up OpenTelemetry in .NET involves a fair amount of boilerplate: configuring resource attributes, wiring up instrumentations, adding OTLP exporters, enriching exceptions, filtering health checks, etc. This library packages all of that into a simple AddOpenTelemetry extension method so you don't have to repeat it across every project.

Packages

Getting Started

ASP.NET Core

dotnet add package Intropy.Telemetry.AspNetCore

using Intropy.Telemetry.AspNetCore;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddOpenTelemetry(config =>
{
    config.ServiceName = "MyService";
    config.Environment = builder.Environment.EnvironmentName;
});

var app = builder.Build();
app.Run();

Console Application

dotnet add package Intropy.Telemetry.ConsoleApp

using Intropy.Telemetry.ConsoleApp;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();

services.AddOpenTelemetry(config =>
{
    config.ServiceName = "MyWorker";
    config.Environment = "Production";
});

var serviceProvider = services.BuildServiceProvider();
using var telemetryScope = new OpenTelemetryScope(serviceProvider);

// Your application code here

What You Get Out of the Box

Tracing

• ASP.NET Core requests (ASP.NET Core package only)
• Outbound HTTP calls
• SQL Client database operations
• gRPC client calls
• Automatic exception enrichment with type, message, and stack trace

Metrics

• ASP.NET Core HTTP request metrics (ASP.NET Core package only)
• HTTP client metrics

Logging

• OTLP export of structured logs

All telemetry is exported via OTLP, configured through standard OpenTelemetry environment variables:

OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317

Configuration

Both packages expose the same configuration pattern via OpenTelemetryConfiguration:

The ASP.NET Core package also exposes:

Full Example

builder.Services.AddOpenTelemetry(config =>
{
    config.ServiceName = "Orders.API";
    config.ServiceNamespace = "mycompany";
    config.Environment = "Production";
    config.ServiceVersion = "2.1.0";

    config.ConfigureTracing = tracing =>
    {
        tracing.AddSource("MyCustomActivitySource");
    };

    config.ConfigureMetrics = metrics =>
    {
        metrics.AddMeter("MyCustomMeter");
    };

    config.ConfigureResource = resource =>
    {
        resource.AddAttributes([
            new KeyValuePair<string, object>("team", "backend")
        ]);
    };
});
