EDOT .NET Migration
Read the migration guide before making changes:
Guidelines
- Remove ALL classic APM references:
Elastic.Apm.*NuGet packages (includingElastic.Apm.NetCoreAll),
UseAllElasticApm() / AddAllElasticApm() calls, the ElasticApm section from appsettings.json, and all
ELASTIC_APM_* env vars
- Add NuGet packages:
Elastic.OpenTelemetryandOpenTelemetry.Instrumentation.AspNetCore(for ASP.NET Core apps)
- Register EDOT in startup: call
builder.AddElasticOpenTelemetry()on theIHostApplicationBuilder(inProgram.cs
or equivalent). Without this, no telemetry is collected
- Set exactly three required environment variables:
OTEL_SERVICE_NAME(replacesELASTIC_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, orOTEL_LOGS_EXPORTER— the defaults are already
correct
- Never run both classic Elastic APM agent (
Elastic.Apm.*) and EDOT on the same application
