EDOT.NET Instrumentation
Read the setup guide before making changes:
Guidelines
- Add NuGet packages:
Elastic.OpenTelemetryandOpenTelemetry.Instrumentation.AspNetCore(for ASP.NET Core apps) - Register EDOT in startup: call
builder.AddElasticOpenTelemetry()on theIHostApplicationBuilder(inProgram.csor 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 <key>" or "Authorization=Bearer <token>"
- Do NOT set
OTEL_TRACES_EXPORTER,OTEL_METRICS_EXPORTER, orOTEL_LOGS_EXPORTER— the defaults are already correct - Do NOT manually configure
TracerProviderorMeterProvider—AddElasticOpenTelemetry()handles everything - Never run both classic Elastic APM agent (
Elastic.Apm.*) and EDOT on the same application
