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. 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.

Service Type ESXi
Instances on a Device 100
Supported Systems/Applications vCenter, ESXi 6.x and later
Device Class Server - ESXi
Monitored By Windows probes
Scan Interval 5 minutes
Datastore Name The name of the monitored Datastore.

This service cannot use Self Healing.

List of Snapshots A list of the record files that store configuration data for ESXi servers at particular points in time.
Guests The 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.
