Utilização da CPU na Partição Principal do Anfitrião do System Center 2012 Virtual Machine Manager

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

Monitoriza a utilização da CPU na partição principal

Knowledge Base article:

Resumo

Este monitor controla o desempenho da CPU do anfitrião. A utilização da CPU excedeu o limiar.

Causas

As máquinas virtuais e cargas de trabalho da partição principal em execução no anfitrião estão a consumir níveis críticos dos recursos de CPU do anfitrião.

Resoluções

Migre máquinas virtuais para outro anfitrião ou reduza o consumo de CPU pela carga de trabalho da partição principal. Para que o Virtual Machine Manager efetue automaticamente o balanceamento entre clusters anfitriões, ative a otimização dinâmica. Para obter mais informações sobre a otimização dinâmica, consulte a documentação do Virtual Machine Manager.
