계측 설정을 OpenTelemetry 표준 환경변수로 받는다.
- DISABLE_INSTRUMENTATION 대신 OTEL_SDK_DISABLED (NodeSDK가 직접 읽음)
- OTEL_EXPORTER_OTLP_ENDPOINT_URL 대신 OTEL_EXPORTER_OTLP_ENDPOINT
(exporter에 url을 넘기지 않아 SDK가 읽음)
- 서비스 이름·버전·환경을 코드에서 빼고 OTEL_SERVICE_NAME,
OTEL_RESOURCE_ATTRIBUTES로 받음 (envDetector)
- .env를 계측 시작 전에 dotenv + dotenv-expand로 읽어, .env의 계측 설정이
적용되고 ${APP_ENV} 확장이 되게 함

- DISABLE_INSTRUMENTATION 대신 OTEL_SDK_DISABLED. Go SDK는 이 변수를 읽지 않아 앱이 같은 이름으로 직접 읽는다 - exporter에 주소·평문 옵션을 넘기지 않아 SDK가 OTEL_EXPORTER_OTLP_ENDPOINT를 읽는다 (http:// 주소면 평문 연결) - resource.WithFromEnv()로 OTEL_SERVICE_NAME, OTEL_RESOURCE_ATTRIBUTES를 읽고 서비스 이름·버전·환경은 코드에서 뺀다 - plag의 span 이름 접두어와 로그 scope 이름을 IRIS에서 PLAG로 바로잡는다 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
- OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_SERVICE_NAME을 configmap에 추가한다. 옛 이미지가 계속 동작하도록 OTEL_EXPORTER_OTLP_ENDPOINT_URL은 남긴다 - OTEL_RESOURCE_ATTRIBUTES=deployment.environment.name=$(APP_ENV)를 deployment env에 추가한다. $(VAR) 치환은 configmap 값이 아니라 파드의 env 항목에서만 일어난다 - client-api·admin-api는 APP_ENV가 이미지에만 있어 치환에 쓸 수 없으므로 stage·production configmap에 APP_ENV를 추가한다 (이미지 값과 같음) Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

service.name을 쿠버네티스 deployment 이름과 같은 소문자로 맞춘다 (CLIENT-API → client-api 등). OTel 예시와 쿠버네티스 관례를 따르고, k8s.deployment.name과 같은 값이 되게 한다. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
서비스 이름은 리소스(service.name)가 담당하므로 코드에서 뺀다. - span 이름의 서비스 접두어 제거 (IRIS:handler:judge → handler:judge) - 로그 scope 이름을 서비스 이름 대신 로거 패키지 경로로 설정 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

서비스 이름은 배포 환경이 아니라 서비스의 정체성이라 코드에 둔다. OTEL_SERVICE_NAME을 주면 여전히 그 값이 우선한다. - backend: Instrumentation.start(serviceName)으로 기본 리소스에 설정 - iris·plag: Init(ctx, serviceName)으로 리소스에 설정 - configmap과 .env.example에서 OTEL_SERVICE_NAME 제거 - 로컬 관측성 스택 README에서 서비스 이름 지정 안내 제거 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

so the OTEL_SDK_DISABLED gate and collector endpoint use values from the file,

Description
서비스들이 관측성 설정(계측 활성화 여부, 데이터를 보낼 주소, 서비스 이름 등)을 OpenTelemetry 표준 환경변수로 받도록 바꿉니다.
지금은 설정 이름이 표준이 아니고, 서비스 버전이 코드에 박혀 있습니다. 서비스 이름(
SERVICE_NAME)만 하드코딩하고 나머지는 각 configmap을 통해 환경 변수로 주입 받도록 수정합니다. 또 client·admin은.env를 계측이 시작된 뒤에 읽어서,.env에 적은 계측 설정이 무시되고 있었습니다.DISABLE_INSTRUMENTATIONOTEL_SDK_DISABLEDOTEL_EXPORTER_OTLP_ENDPOINT_URL(표준 아님)OTEL_EXPORTER_OTLP_ENDPOINT"CLIENT-API"등)client-api,admin-api,iris,plag).OTEL_SERVICE_NAME을 주면 그 값이 우선APP_ENV를 읽음OTEL_RESOURCE_ATTRIBUTES에서APP_ENV로 만듦2.2.0(2025년 5월 이후 안 바뀐 값).env를 먼저 읽습니다.IRIS, plag는 잘못 적힌IRIS)을 뺐습니다. 어느 서비스인지는 서비스 이름 라벨(SERVICE_NAME)로 구분합니다. 예:IRIS:handler:judge→handler:judgeAdditional context
