Utilizzo memoria dell'host per System Center 2012 Virtual Machine Manager

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

Consente di monitorare l'utilizzo della memoria dell'host

Knowledge Base article:

Riepilogo

Questo monitoraggio registra la quantità di memoria utilizzata nell'host, in megabyte (MB). La memoria disponibile per l'host è inferiore alla soglia specificata.

Cause

Le macchine virtuali in esecuzione nell'host utilizzano livelli critici della memoria dell'host.

Soluzioni

Per liberare memoria nell'host, eseguire la migrazione di una macchina virtuale in un altro host. È possibile abilitare la funzionalità di ottimizzazione dinamica e lasciar bilanciare automaticamente i cluster host da Virtual Machine Manager. Per informazioni sull'ottimizzazione dinamica, vedere la documentazione di Virtual Machine Manager.
