Get-DbaDiskSpace returning blank values

PowerShell Help
1

I am using this cmdlet from dbatools to report on low disk space: Get-DbaDiskSpace

Sometimes it returns blanks for certain drives like this:

ComputerName Name Label Capacity Free PercentFree
server1 D:\
server2 E:\
server3 G:\ sql_tempDB 99.89 GB 9.97 MB 0.01
Here is my code: 
$allservers  = Get-DbaCmsRegServer -SqlInstance localhost -Group myCMSgroup


$results = $allservers | Get-DbaDiskSpace | Where-Object PercentFree -lt 10


if($results.count -gt 0) {

$style = “<style>BODY{font-family: Arial; font-size: 10pt;}”

$style = $style + “TABLE{border: 1px solid black; border-collapse: collapse;}”

$style = $style + “TH{border: 1px solid black; background: #dddddd; padding: 5px; }”

$style = $style + “TD{border: 1px solid black; padding: 5px; }”

$style = $style + “</style>”


$smtpServer = “smtprelay.us.myDomain.com”

$smtpFrom = “noReply@myDomain.com”

$smtpTo = “kevin.j.sexton@myDomain.com”

$messageSubject = “Drives with less than 10% free space (PROD) (task:Drive Space Monitor-ks)”


$message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto

$message.Subject = $messageSubject

#$message.Body = $allservers | Get-DbaDiskSpace | Where-Object PercentFree -lt 10  | select-object ComputerName,Name,Label,Capacity,Free,PercentFree | convertto-html -Head $style

$message.Body = $results  | select-object ComputerName,Name,Label,Capacity,Free,PercentFree | convertto-html -Head $style


$message.IsBodyHTML = $true


$smtp = New-Object Net.Mail.SmtpClient($smtpServer)

$smtp.Send($message)

}

Just to check free space, you don’t need to go for Get-DbaDiskSpace. Use Get-Volume cmdlet.
