This article details how to generate report using the RestAPI which will mirror as closely as possible the "OutputDevices" report which was available in V3 of iQSonar.
You can download the latest version of the file: OutputDevices-v1.ps1, and simply customise the $user, $pass and $sonar values and it should run in your environment

| PhysicalFQDN | Fully Qualified Domain Name of the Physical Device | Get this from the /devices/{Device_ID} RestAPI endpoint; May not always be available |
| IP Address |
| V4 also exposes IP6 addresses. |
| PhysicalMACAddress | If more than 1, will be semi-colon separated. | |
| VirtualMACAddress | If more than 1, will be semi-colon separated. | |
| ClusterInformation | The virtualization cluster that the physical machine is part of | Only available if it is part of a cluster, and the cluster has been scanned |
| ClusterName | Name of cluster | Only available if it is part of a cluster, and the cluster has been scanned |
| PartitioningMethod | Virtualization Method (VMware, HyperV, LPAR etc.). If this field is null it indicates the device is physical. | |
| DerivedCPU | Not directly available via RestAPI. Must be coded in the script. | |
| DerivedCoresPerCPU | Not directly available via RestAPI. Must be coded in the script. | |
| Bios | Concatenation of Device.BIOSName, DeviceBIOSManufacturer, Device.BIOSVersion separated by semi-colons. | Get this from the /devices/{Device_ID} RestAPI endpoint. |
| LastScanDate | Last date the device was scanned | Get this from the /devices/{Device_ID} RestAPI endpoint. |
| DeviceID | The unique identifier for this device | The Rest API gives unique identifiers in GUID format |
| PhysicalDeviceID | The unique identifier of the Physical Device (where relevant) – used to map logical devices or Virtual machines back to the Physical Device which hosts them. | Get this from the /devices/{Device_ID} RestAPI endpoint; May not always be available |
| PhysicalCPUNotes | Notes that indicate CPU vs socket mismatches or CPU core values that don’t match the CPU model | This V3 data is not directly available via RestAPI. This functionality is part of DataHub for V4, and if required must be coded in the script. |

The script above works to extract the data, but if you want to feed the CSV file to a data processing application which was written for a V3 datasource, you probably want to have the columns in the "correct" order (including empty columns) so that your third party application does not need to be reconfigured or re-written. So, to Simply calling the "Export-CSV" cmdlet as shown above is insufficient, as the ordering of the columns is determined by the cmdlet rather than by the initial ordering we defined. To force all the columns to be saved, including the columns that are always empty, and to have the columns in the correct order corresponding to the original V3 file, we use the Select-Object powershell cmdlet, and then pipe the results into the Export-CSV cmdlet.
