EDOT Java Migration Read the migration guide before making changes: Migration guide EDOT Java setup EDOT Java configuration Guidelines Remove ALL classic APM references: elastic-apm-agent.jar , elasticapm.properties , all ELASTIC_APM_* env vars, and any co.elastic.apm Maven/Gradle dependencies Use elastic-otel-javaagent.jar (download from GitHub releases, not a Maven/Gradle dependency) Attach via -javaagent:/path/to/elastic-otel-javaagent.jar or JAVA_TOOL_OPTIONS="-javaagent:/path/to/elastic-otel-javaagent.jar" — without this the agent does nothing Set exactly three required environment variables: OTEL_SERVICE_NAME (replaces ELASTIC_APM_SERVICE_NAME ) OTEL_EXPORTER_OTLP_ENDPOINT — must be the managed OTLP endpoint or EDOT Collector URL. Do NOT reuse the old ELASTIC_APM_SERVER_URL value. Never use an APM Server URL (no apm-server , no :8200 , no /intake/v2/events ) OTEL_EXPORTER_OTLP_HEADERS — "Authorization=ApiKey " or "Authorization=Bearer " (replaces ELASTIC_APM_SECRET_TOKEN / API_KEY ) 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 and EDOT agent on the same JVM Examples See the EDOT Java migration guide for complete examples.
