그라파나 대시보드
다양한 대시보드와 그라파나에서 시각화할 수 있는 메트릭을 직접 살펴보세요.
TIP
너무 많은 대시보드를 생성하지 마세요(‘그래프의 장벽’). 엔지니어가 문제를 해결해야 하는 상황에서 원인을
파악하기가 어려워집니다. 대시보드에 더 많은 정보가 있으면 모니터링하기에 더 좋을 것이라고 생각할지도
모르겠네요. 하지만 정보가 많으면 대시보드를 보는 사용자에게 혼란을 줄 수 있습니다. 대시보드를 설계할 때
문제 해결 시간과 결과에 중점을 두세요.

로깅 개요
지금까지 메트릭과 쿠버네티스에 대한 많은 내용을 논의했습니다. 하지만 전체 환경을 보려면
쿠버네티스 클러스터와 클러스터에 배포된 애플리케이션으로부터 로그를 수집하여 중앙집중
화해야 합니다.
누군가는 ‘모든 것을 기록합시다’라고 쉽게 말할 수도 있습니다. 하지만 이에 따른 두 가지 문제
가 발생합니다.
●
너무 많은 노이즈 때문에 문제를 빠르게 발견하기 어렵습니다.
●
많은 리소스 사용으로 인한 높은 비용이 발생합니다.
