추천
현재 CPU 사용률 추세를 기준으로 클러스터가 CPU 사용량이 많은 것으로 플래그 지정됩니다.
하위 유형: HIGH_INSTANCE_CPU_UTILIZATION
CPU 크기를 늘리거나 CPU 사용률을 줄입니다.
하위 유형: INCREASE_PRIMARY_INSTANCE_SIZE
현재 메모리 사용률 추세를 기준으로 클러스터가 메모리 사용량이 많은 것으로 플래그 지정됩니다.
하위 유형: HIGH_INSTANCE_MEMORY_UTILIZATION
메모리 크기를 늘리거나 메모리 사용률을 줄입니다.
하위 유형: INCREASE_PRIMARY_INSTANCE_SIZE
Google Cloud 콘솔을 사용하여 추천 적용
추천을 신중하게 평가하고Google Cloud 콘솔에서 다음을 실행하여 추천을 구현합니다.
클러스터에서 수정을 클릭합니다.
기본 인스턴스 수정 창에서 vCPU와 메모리가 더 많은 머신 유형으로 전환합니다.
클러스터 크기를 정확히 추천받은 만큼 조정할 필요는 없습니다. 자신의 클러스터 프로비저닝 방식에 따라 크기를 판단하여 조정합니다.
