EDOT .NET Instrumentation Read the setup guide before making changes: EDOT .NET setup EDOT .NET configuration OpenTelemetry .NET instrumentation Guidelines Add NuGet packages: Elastic.OpenTelemetry and OpenTelemetry.Instrumentation.AspNetCore (for ASP.NET Core apps) Register EDOT in startup: call builder.AddElasticOpenTelemetry() on the IHostApplicationBuilder (in Program.cs or equivalent). Without this, no telemetry is collected Set exactly three required environment variables: OTEL_SERVICE_NAME OTEL_EXPORTER_OTLP_ENDPOINT — must be the managed OTLP endpoint or EDOT Collector URL. Never use an APM Server URL (no apm-server , no :8200 , no /intake/v2/events ) OTEL_EXPORTER_OTLP_HEADERS — "Authorization=ApiKey " or "Authorization=Bearer " Do NOT set OTEL_TRACES_EXPORTER , OTEL_METRICS_EXPORTER , or OTEL_LOGS_EXPORTER — the defaults are already correct Do NOT manually configure TracerProvider or MeterProvider — AddElasticOpenTelemetry() handles everything Never run both classic Elastic APM agent ( Elastic.Apm.* ) and EDOT on the same application Examples See the EDOT .NET setup guide for complete examples.
