Datastore (VMware) service

The Datastore (VMware) service monitors the storage location for virtual machine files on ESXi servers.

N-able N-central uses the CIM services and ports for monitoring. Managed Object Browser (MOB) access is also required for this service.

The agent can monitor up to 100 datastores.

If your ESX/ESXi server is operating on either Dell or HP hardware, it is strongly recommended that you install the Dell or HP Offline Bundle before the Windows probe discovers the ESX/ESXi server.

Instances on a Device100

To access information on the Datastores on your ESXi server, use a browser to access the following URL:


Sometimes data is nested within sub-pages. Make sure that you click through those sub-pages for the data.

Note that the MOB by default may be disabled and you may need to enable this feature.

Metric NameDescription
Total Disk Space (GB)The total size of the datastore.
Disk Space Used (GB)The amount of space currently in use on the datastore.
Disk Space Free (GB)The amount of space that is currently unoccupied on the datastore.
Disk Usage (%)The amount of space currently unoccupied on the datastore expressed as a percentage of the total space.
List of SnapshotsA list of the record files that store configuration data for ESXi servers at particular points in time.
GuestsThe virtual machine guest operating systems currently configured on the ESXi server.
Total Disk Space used by all Virtual Machine files (GB) The amount of space is taken from the size property of the "VirtualMachineFileLayoutExFileInfo" class. The total size is in bytes, and includes all virtual machine files including the original snapshot.
Total Disk Space used by Snapshot Overhead files (GB) The amount of space currently used by all snapshot files since the original snapshot but not including the original snapshot.
