OpenSearch Dashboards는 OpenSearch 데이터를 시각화하고 상호 작용할 수 있는 강력한 도구입니다. 그러나 이를 최대한 활용하려면 로깅과 관련된 구성 설정을 이해해야 합니다. 아래에서는 주요 옵션과 배포에 대한 의미에 대해 깊이 탐구합니다.

1. 로깅 쿼리 설정: opensearch.logQueries
이 설정은 대시보드에서 OpenSearch로 전송되는 모든 쿼리의 로깅을 활성화합니다. 기본적으로는 비활성화되어 있습니다 (false) 하지만, 활성화되면 (true), 그리고 logging.verbose와 결합되면, 대시보드가 생성하는 쿼리에 대한 상세한 통찰력을 제공합니다. 이는 디버깅 및 성능 최적화에 대단히 가치가 있습니다.

2. 로그 대상으로 지정하기: logging.dest
기본적으로 OpenSearch Dashboards는 출력을 stdout (콘솔)로 로그합니다. 그러나 이 설정을 통해 경로를 지정하여 로그를 파일로 리디렉션할 수 있습니다. 이는 특히 컴플라이언스나 문제 해결을 위해 영구적인 로그 기록이 필요한 경우 유용합니다.

3. 디스크 공간 오류 처리: logging.ignoreEnospcError
디스크 공간 문제는 치명적일 수 있습니다. logging.ignoreEnospcError 설정을 활성화하면 true대시보드 프로세스가 ENOSPC (장치에 남은 공간 없음) 오류로 인해 중단되는 것을 방지합니다. 이는 다운타임을 방지하지만 스토리지를 주의 깊게 모니터링하여 다른 잠재적 문제를 피해야 합니다.

4. 로그 출력 관리: logging.silent 및 logging.quiet

logging.silent: 모든 로그 출력을 억제합니다. 이는 로깅이 불필요한 상황에 유용하지만 디버깅에는 적합하지 않습니다.
logging.quiet: 오류 메시지만 출력하여 로그 소음을 최소화하면서도 주요 문제에 대한 경고를 받을 수 있는 환경에 중간 정도의 해결책을 제공합니다.

5. 상세 로그 활성화: logging.verbose
포괄적인 통찰력을 위해 logging.verbose 를 true로 설정하세요. 이 설정은 시스템 자원 사용에서 모든 수신 요청까지 모든 것을 로그하여 성능 또는 구성 문제를 진단할 수 있는 강력한 도구입니다.

OpenSearch Dashboards 로깅 구성 팁

프로덕션에 적용하기 전에 항상 스테이징 환경에서 변경 사항을 테스트하십시오.
로깅 설정을 전략적으로 사용하십시오: 디버깅을 위해 일시적으로 상세 로깅을 활성화하고, 성능을 위해 프로덕션에서 조용하거나 무음 모드로 전환하십시오.

이러한 로깅 설정을 이해하고 조정함으로써, 고유한 요구에 맞춰 OpenSearch Dashboards를 최적화하고 안전하고 효율적이며 사용자 친화적인 경험을 보장할 수 있습니다.
