System Center 2016 Virtual Machine Manager Storage Pool Capacity

Microsoft.SystemCenter.VirtualMachineManager.2016.StoragePoolCapacityMonitor (UnitMonitor)

Monitors storage pool capacity usage

Knowledge Base article:

Summary

The Storage Pool Capacity monitor tracks the available capacity of storage pools in VMM. When storage usage approaches the available storage pool capacity, the monitor will go into a warning or critical state.

Causes

Storage usage of the storage pool is approaching the pool’s available capacity. By default, when storage usage exceeds 80% of capacity, the monitor will go into a warning state and when storage usage exceeds 90% of 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 storage pool’s capacity

Reduce storage usage within the pool

Override the warning and critical thresholds of the monitor
