BuildingBlocks.Telemetry

Config-driven OpenTelemetry metrics, logging, and tracing for .NET.

NuGet License: MIT

What's new in 1.0.1

  • IntegrateMediator also AddMeter("BuildingBlocks.Mediator") so Send metrics export with traces
  • TelemetryDefaults.MediatorMeter (same name as the mediator ActivitySource)

Requirements

  • .NET 8, .NET 9, or .NET 10 (net8.0 / net9.0 / net10.0)
  • IHostApplicationBuilder (Microsoft.AspNetCore.App)

Install

dotnet add package BuildingBlocks.Telemetry

Quick start

builder.AddTelemetry(o =>
{
    o.IntegrateMediator = true;
    o.Instrumentation.Npgsql = true;
    o.Instrumentation.EventBus = true;
});

builder.AddTelemetry(
    configureOptions: o => o.EnableMetrics = true,
    configureBuilder: t => t.AddSource("DbMigrations"));

OTLP turns on when OTEL_EXPORTER_OTLP_ENDPOINT is set. Prefer env over hard-coded endpoints. On that fast-path, Exporters.Otlp.Protocol is ignored; use OTEL_EXPORTER_OTLP_PROTOCOL.

Features

  • Tracing, metrics, and logs from one AddTelemetry call
  • Stable instrumentations: ASP.NET Core, HttpClient, Runtime, Npgsql (on by default); SqlClient opt-in
  • Framework meters: Hosting, Kestrel, Routing, Diagnostics, Auth, MemoryPool, Http, DNS
  • Health/metrics path filter (/health, /alive, /ready, /metrics)
  • RecordException and SetErrorStatusOnException
  • telemetry.component span tag for filtering
  • Startup summary log: service name, environment, signals, exporter modes, instrumentation — plus a warning when no exporter is configured
  • Source-only: Mediator (IntegrateMediator), EventBus, MassTransit
  • Exporters: OTLP, Console, optional Azure Monitor
  • ParentBased sampling; AlwaysOn in Development unless TracesSamplerRatio is set
  • Trace-based exemplars; deployment.environment / service.environment resource attributes
  • TelemetryActivity for manual spans
  • TelemetryBuilder hooks: ConfigureTracing / ConfigureMetrics / ConfigureLogging / AddSource / AddMeter

ConfigureAspNetCore / ConfigureHttpClient / ConfigureSqlClient order: Filter / RecordException → user callback → telemetry.component.

Extra instrumentations (not shipped here) go through TelemetryBuilder.ConfigureTracing.

Startup summary

One Information log after host start, e.g.:

BuildingBlocks.Telemetry ready for catalog-api in Development. Signals: traces, metrics, logs.
Exporters: OTLP (environment). Instrumentation: aspnetcore, httpclient, runtime, npgsql, framework-meters, mediator.

Endpoints, OTLP headers, and connection strings are never logged. Silence it with a log filter on BuildingBlocks.Telemetry.Internal.Pipeline.TelemetryStartupSummaryReporter.
