Využití procesoru hostitele nástroje System Center 1801+ Virtual Machine Manager

Microsoft.SystemCenter.VirtualMachineManager.HostCPUUtilizationMonitor (UnitMonitor)

Sleduje využití procesoru hostitele.

Knowledge Base article:

Souhrn

Tento monitor sleduje výkon procesoru hostitele. Hodnota využití procesoru překročila prahovou hodnotu.

Příčiny

Virtuální počítače spuštěné v hostitelském počítači spotřebovávají kritickou úroveň prostředků procesoru hostitele.

Řešení

Chcete-li uvolnit prostředky procesoru, proveďte migraci některého virtuálního počítače na jiného hostitele. Rovněž lze povolením dynamické optimalizace nechat nástroj Virtual Machine Manager, aby automaticky optimalizoval clustery hostitele. Informace o dynamické optimalizaci získáte v dokumentaci k nástroji Virtual Machine Manager.
