System Center 2019+ Virtual Machine Manager Geheugengebruik op host

Microsoft.SystemCenter.VirtualMachineManager.HostMemoryUtilizationMonitor (UnitMonitor)

Hiermee wordt het geheugengebruik op de host bewaakt

Knowledge Base article:

Samenvatting

Deze monitor houdt bij hoeveel geheugen op de host wordt gebruikt (in MB). Het beschikbare geheugen voor de host ligt onder de drempelwaarde.

Oorzaken

De virtuele machines op de host verbruiken kritieke niveaus aan hostgeheugen.

Oplossingen

Migreer een virtuele machine naar een andere host om extra hostgeheugen vrij te maken U kunt de taakverdeling van hostclusters ook automatisch optimaliseren met Virtual Machine Manager door dynamische optimalisatie in te schakelen. Raadpleeg de documentatie bij Virtual Machine Manager voor meer informatie over dynamische optimalisatie.
