Uso de memoria del host de System Center 2019+ Virtual Machine Manager

Microsoft.SystemCenter.VirtualMachineManager.HostMemoryUtilizationMonitor (UnitMonitor)

Supervisa el uso de memoria del host

Knowledge Base article:

Resumen

Este monitor realiza un seguimiento de la cantidad de memoria usada en el host en megabytes. La memoria disponible para el host es inferior al umbral.

Causas

Las máquinas virtuales que se ejecutan en el host están consumiendo cantidades críticas de memoria.

Resoluciones

Para liberar memoria adicional del host, migre una máquina virtual a otro host. Para que Virtual Machine Manager equilibre automáticamente la carga de los clústeres de hosts, habilite la característica de optimización dinámica. Para obtener más información acerca de la optimización dinámica, vea la documentación de Virtual Machine Manager.
