System Center 2012 Virtual Machine Manager Cloud StorageUsageGB

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

Monitors private cloud storage usage (in gigabytes)

Knowledge Base article:

Summary

The Cloud Storage Usage monitor tracks the storage usage (in gigabytes) of virtual machines and service instances running in the private cloud. When storage usage approaches the defined private cloud capacity, the monitor will go into a warning or critical state.

Causes

Storage usage within the private cloud is approaching the defined cloud capacity. By default, when storage usage exceeds 80% of private cloud capacity, the monitor will go into a warning state and when storage usage exceeds 90% of private cloud capacity, the monitor will go into a critical state. Each of these thresholds is overrideable.

Resolutions

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

Redefine the private cloud capacity limits

Reduce storage usage within the private cloud

Override the warning and critical thresholds of the monitor
