Scripts: Export VM Name and VMDK Size

1 minute read

Here is a script that I use to gather some size data and spit out a spreadsheet listing name and VMDK size.

# PowerCLI Script to gather VM Information (Name, VMDK Size)

#Global Functions
function Get-VmSize($vm)
{
#Initialize variables
$VmDirs =@()
$VmSize = 0

$searchSpec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec
$searchSpec.details = New-Object VMware.Vim.FileQueryFlags
$searchSpec.details.fileSize = $TRUE

Get-View -VIObject $vm | % {
#Create an array with the vm's directories
$VmDirs += $_.Config.Files.VmPathName.split("/")[0]
$VmDirs += $_.Config.Files.SnapshotDirectory.split("/")[0]
$VmDirs += $_.Config.Files.SuspendDirectory.split("/")[0]
$VmDirs += $_.Config.Files.LogDirectory.split("/")[0]
#Add directories of the vm's virtual disk files
foreach ($disk in $_.Layout.Disk) {
foreach ($diskfile in $disk.diskfile){
$VmDirs += $diskfile.split("/")[0]
}
}
#Only take unique array items
$VmDirs = $VmDirs | Sort | Get-Unique

foreach ($dir in $VmDirs){
$ds = Get-Datastore ($dir.split("[")[1]).split("]")[0]
$dsb = Get-View (($ds | get-view).Browser)
$taskMoRef  = $dsb.SearchDatastoreSubFolders_Task($dir,$searchSpec)
$task = Get-View $taskMoRef

while($task.Info.State -eq "running" -or $task.Info.State -eq "queued"){$task = Get-View $taskMoRef }
foreach ($result in $task.Info.Result){
foreach ($file in $result.File){
$VmSize += $file.FileSize
}
}
}
}

return $VmSize
}

}
$Report += $Details
}

$Report | Export-Csv "C:VMDiskSize.csv"

# Disconnect from VIServer
