Microservices Observability with OpenTelemetry

OpenTelemetry is becoming the standard for distributed tracing and metrics. Here’s how to instrument .NET apps.

Three Pillars

• Traces: Request flow across services
• Metrics: Counters, gauges, histograms
• Logs: Structured logging with context

.NET Setup

services.AddOpenTelemetryTracing(builder => builder
    .AddAspNetCoreInstrumentation()
    .AddHttpClientInstrumentation()
    .AddJaegerExporter());
