Data Collection Options and Datastore Utilization
A Virtualization Manager data collection policy can be configured to gather data as follows:
Inventory (default option): Collect only the data associated with the VMs in the inventory.
Collect all files in datastore: Perform a full scan of the datastore to discover files that are resident on the datastore, but not associated with a VM in the inventory. This option finds files that may be invisible to VMware, but that are consuming space on the datastore.
When the Inventory option is configured in the data collector policy, it has the following impact on fields shown in this report:
VM Not In Inventory will be zero.
Total VM Used will be reduced by the amount that would have been collected as VM Not In Inventory if an all files collection had been done.
