EDOT .NET Migration

Read the migration guide before making changes:

Guidelines

Remove ALL classic APM references: Elastic.Apm.* NuGet packages (including Elastic.Apm.NetCoreAll ), UseAllElasticApm() / AddAllElasticApm() calls, the ElasticApm section from appsettings.json , and all ELASTIC_APM_* env vars
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 (replaces ELASTIC_APM_SERVICE_NAME / ElasticApm:ServiceName )
OTEL_EXPORTER_OTLP_ENDPOINT — must be the managed OTLP endpoint or EDOT Collector URL. Do NOT reuse the old ELASTIC_APM_SERVER_URLS value. 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>" (replaces ELASTIC_APM_SECRET_TOKEN )
Do NOT set OTEL_TRACES_EXPORTER , OTEL_METRICS_EXPORTER , or OTEL_LOGS_EXPORTER — the defaults are already correct
Never run both classic Elastic APM agent (Elastic.Apm.* ) and EDOT on the same application

Examples

See the EDOT .NET migration guide for complete examples.
