EDOT Java Migration

Read the migration guide before making changes:

Guidelines

  1. Remove ALL classic APM references: elastic-apm-agent.jar, elasticapm.properties, all ELASTIC_APM_* env vars, and any co.elastic.apm Maven/Gradle dependencies
  2. Use elastic-otel-javaagent.jar (download from Maven Central, not a Maven/Gradle compile dependency)
  3. 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
  4. 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 <key>" or "Authorization=Bearer <token>" (replaces ELASTIC_APM_SECRET_TOKEN / API_KEY)
  5. Do NOT set OTEL_TRACES_EXPORTER, OTEL_METRICS_EXPORTER, or OTEL_LOGS_EXPORTER — the defaults are already correct
  6. Never run both classic Elastic APM agent and EDOT agent on the same JVM

Examples
