[CommonParameters]

Parameters

Required	Parameter Name	Type	Position	Features	Description
required	PredefinedTimeRange	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	Entity	VIObjectCore[]	named	pipeline wildcards	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	Name	String[]	named	wildcards	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	ProgressAction	ActionPreference	named
optional	Server	VIServer[]	named	wildcards	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.

Required	Parameter Name	Type	Position	Features	Description
optional	EndTime	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	Entity	VIObjectCore[]	named	pipeline wildcards	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	Name	String[]	named	wildcards	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	ProgressAction	ActionPreference	named
optional	Server	VIServer[]	named	wildcards	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	StartTime	DateTime	named		Specifies the client local time from which you want to retrieve statistics. The returned samples do not include the sample at StartTime.
