Retrieve Template Information using PowerCLI

It is possible to retrieve template information using the Get-Template cmdlet to obtain a number of properties. In this example I will be looking to retrieve the following items and export to comma-separated values (CSV) file:

  • Name
  • vCPU
  • Memory
  • Number of Hard Disks
  • Size of Hard Disks

Firstly, we will connect to the VI Server and return a collection of templates using the Get-Template cmdlet.

If (-not (Get-PSSnapin VMware.VimAutomation.Core -ErrorAction SilentlyContinue)) 
    {
    Add-PSSnapin VMware.VimAutomation.Core > $null
    }

Connect-VIServer server1.domain.local
$Templates = Get-Template

For each template  in the collection we will retrieve the above items and store these in a variable for exporting to a CSV file. For the number of hard disks, these will count the number retrieved and for size join the values to a single string by invoking the Get-HardDisk cmdlet.

$Inventory= ForEach ($Template in$Templates)
    { 

"" | Select-Object -Property @{N="Name";E={$Template.Name}},
      @{N="vCPU";E={$Template.ExtensionData.Config.Hardware.NumCPU}},
      @{N="Memory (MB)";E={$Template.ExtensionData.Config.Hardware.MemoryMB}},    
      @{N="Number of Hard Disks";E={($Template | Get-HardDisk | Measure-Object).Count}},
      @{N="Size of Hard Disks";E={[string]::Join(',',(($Template |Get-HardDisk).CapacityKB))}}

    } 
$Inventory | Export-Csv -NoTypeInformation -UseCulture -Path ("D:\Output\" + [guid]::NewGuid() + "-inv_template.csv")
