System Center 2012 Virtual Machine Manager 主机内存使用率

Microsoft.SystemCenter.VirtualMachineManager.2012.HostMemoryUtilizationMonitor (UnitMonitor)

监视主机内存使用率

Knowledge Base article:

概述

此监视器跟踪主机上的内存使用量（以 MB 为单位）。主机的可用内存小于阈值。

原因

主机上运行的虚拟机所消耗的主机内存已达到严重级别。

解决方案

要释放额外的主机内存，请将虚拟机迁移到另一个主机。要让 Virtual Machine Manager 自动对主机群集进行负载平衡，请启用动态优化功能。有关动态优化的信息，请参阅 Virtual Machine Manager 文档。
