Get-VsanStat
This cmdlet retrieves vSAN performance statistics for the specified server entity.
Syntax
[-Entity <VIObjectCore[]>]
[-Name <String[]>]
[-Server <VIServer[]>]
[-StartTime <DateTime>]
[CommonParameters]
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| optional |
|
DateTime | named |
|
Specifies the client local time up to which you want to retrieve statistics. If the specified value is later than current server time, the value is replaced by the current server time. The returned samples include the sample at EndTime. | optional |
|
VIObjectCore[] | named |
|
Specifies the entity for which you want to retrieve vSAN performance metrics. OBN is supported for the Cluster, VMHost, VirtualMachine, VsanIscsiTarget, and VsanStoragePoolDisk (vSphere 8.0 and later) entity types. | optional |
|
String[] | named |
|
Specifies the performance metrics you want to retrieve. If not specified, all the metrics are returned. The value is in the format 'ViewName.MetricName'. ViewName is applicable to different entity types: Cluster: Backend, VMConsumption, Capacity VMHost: Backend, VMConsumption, HostNetwork, HostIscsi VirtualMachine: Performance HardDisk: VirtualDisk, Vscsi VsanDisk: Performance VsanDiskGroup: Performance VsanStoragePoolDisk: Performance VsanIscsiTarget: Performance VsanIscsiLun: Performance HostVirtualNic: Performance PhysicalNic: Performance VsanFileShare: Performance | optional |
|
VIServer[] | named |
|
Specifies the vCenter Server systems on which you want to run the cmdlet. If no value is provided or $null value is passed to this parameter, the command runs on the default servers. For more information about default servers, see the description of the Connect-VIServer cmdlet. | optional |
|
DateTime | named |
|
Specifies the client local time from which you want to retrieve statistics. The returned samples do not include the sample at StartTime. |

[CommonParameters]
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| required |
|
VsanPredefinedTimeRange | named |
|
A list of predefined time ranges (Last5Minutes, Last15Minutes, Last30Minutes, LastHour, Last24Hours, LastWeek) provides a more efficient way to specify time range in querying vSAN performance metric than using the StartTime and EndTime parameters. | optional |
|
VIObjectCore[] | named |
|
Specifies the entity for which you want to retrieve vSAN performance metrics. OBN is supported for the Cluster, VMHost, VirtualMachine, VsanIscsiTarget, and VsanStoragePoolDisk (vSphere 8.0 and later) entity types. | optional |
|
String[] | named |
