System Center 2016 Virtual Machine Manager 호스트 메모리 사용률

Microsoft.SystemCenter.VirtualMachineManager.2016.HostMemoryUtilizationMonitor (UnitMonitor)

호스트 메모리 사용률을 모니터링합니다.

Knowledge Base article:

요약

이 모니터는 호스트에 사용되는 메모리의 양을 MB 단위로 추적합니다. 호스트에사용가능한메모리가임계값보다적습니다.

원인

호스트에서실행중인가상컴퓨터가호스트메모리를위험수준으로사용하고있습니다.

해결 방법

호스트 메모리를 확보하려면 가상 컴퓨터를 다른 호스트로 마이그레이션합니다. Virtual Machine Manager가 호스트 클러스터의 부하를 자동으로 분산하도록 하려면 동적 최적화 기능을 사용하십시오. 동적 최적화에 대한 자세한 내용은 Virtual Machine Manager 설명서를 참조하십시오.
