System Center 2012 Virtual Machine Manager Cloud CPUUsageCount

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

Monitors the private cloud CPU usage count

Knowledge Base article:

Summary

The Cloud CPU Usage monitor tracks the CPU usage of the private cloud. When CPU usage approaches the defined private cloud capacity, the monitor will go into a warning or critical state.

Causes

CPU usage within the cloud is approaching the defined private cloud capacity. By default, when CPU usage exceeds 90% of private cloud capacity, the monitor will go into a critical state. This threshold is overrideable.

Resolutions

To return the monitor to a healthy state, you may:

Redefine the private cloud capacity limits

Reduce CPU usage within the private cloud

Override critical threshold of the monitor
