System Center 2012 Virtual Machine Manager - Utilização de CPU do Host

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

Monitora a utilização de CPU do host

Knowledge Base article:

Resumo

Esse monitor rastreia o desempenho de CPU do host. A utilização de CPU excedeu o limite.

Causas

As máquinas virtuais em execução no host estão consumindo níveis críticos dos recursos de CPU no host.

Resoluções

Para liberar recursos de CPU, faça a migração de uma máquina virtual para outro host. Também é possível fazer com que o Virtual Machine Manager otimize clusters de hosts automaticamente, habilitando a Otimização Dinâmica. Para obter informações sobre a Otimização Dinâmica, consulte a documentação do Virtual Machine Manager.
