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

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

Monitora l'utilizzo della CPU dell'host

Knowledge Base article:

Riepilogo

Questo monitoraggio tiene traccia delle prestazioni della CPU nell'host. L'utilizzo della CPU è risultato superiore alla soglia specificata.

Cause

Le macchine virtuali in esecuzione nell'host utilizzano livelli critici di risorse della CPU nell'host.

Soluzioni

Per liberare risorse della CPU, eseguire la migrazione di una macchina virtuale in un altro host. È possibile inoltre abilitare l'ottimizzazione dinamica e lasciare eseguire automaticamente l'ottimizzazione dei cluster host da Virtual Machine Manager. Per informazioni sull'ottimizzazione dinamica, vedere la documentazione di Virtual Machine Manager.
