Powershell script to find freespace available on disk and send email

Question

Here is the code and I am getting email The F: drive is below 150 GB and only at 0 GB - Please resolve, but that is not true. F drive is not low in space

$disksize = $null

$limitGB = $null

$freeSpaceGB = $null

Parameter

$limitGB = 150

$disksize = Get-WmiObject -ComputerName servername-SharepointDB -Class Win32_LogicalDisk | Where-object Name -eq "F:"

$freeSpaceGB = [math]::round($disksize.FreeSpace/1GB, 2)

If ($freeSpaceGB -lt $limitGB) {

$options = @{

'SmtpServer' = "server.smtp.com" 

'To' = "Recipient"

'From' = "sender" 

'Subject' = "F: Drive space threshold reached - $freeSpaceGB GB Free" 

'Body' = "The F: drive is below 150 GB and only at $freeSpaceGB GB - Please resolve" 

 }

Send-MailMessage @options

Hi @Avyayah ,

is there an "F:-Drive"?

Please check the value of $disksize in your script if there is a "F:-Drive" found:

$disksize = $null
$limitGB = 150
$disksize = Get-WmiObject -ComputerName localhost -Class Win32_LogicalDisk  | Where-object Name -eq "F:"
if ($disksize) {
    $freeSpaceGB = [math]::round($disksize.FreeSpace/1GB, 2)
    if ($freeSpaceGB -lt $limitGB) {
        Write-Output "running out of space - $freeSpaceGB GB free"
    } else {
        Write-Output "enough space - $freeSpaceGB GB free "
    }
} else {
    Write-Output "No F: drive found "
}

You can run this to get the disks and check which drives are found:

Get-WmiObject -ComputerName localhost -Class Win32_LogicalDisk

With this code it execute email that 702 GB left. But I guess when disk space is down it should alert me

Hi @Avyayah ,

not tested but it should help (you can increase the limitGB value for testing):

$disksize = $null
$limitGB = 150
$disksize = Get-WmiObject -ComputerName localhost -Class Win32_LogicalDisk  | Where-object Name -eq "F:"
if ($disksize) {
    $freeSpaceGB = [math]::round($disksize.FreeSpace/1GB, 2)
    if ($freeSpaceGB -lt $limitGB) {
        Write-Output "running out of space - $freeSpaceGB GB free"
        
        $sendMailMessage = @{
            From = 'User01 <user01@fabrikam.com>'
            To = 'User02 <user02@fabrikam.com>'
            Subject = 'F: Drive space threshold reached - $freeSpaceGB GB Free'
            Body = "The F: drive is below 150 GB and only at $freeSpaceGB GB - Please resolve"
            SmtpServer = 'server.smtp.com'
        }
        Send-MailMessage @sendMailMessage

    } else {
        Write-Output "enough space - $freeSpaceGB GB free "
    }
} else {
    Write-Output "No F: drive found "
}

Hi @Avyayah , try this:

$Drive = "C:"
$FreeSpace = (Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceID='$Drive'").FreeSpace /1gb -as [int]
$Limit = 10
if ($FreeSpace -lt $Limit) {

    $EmailFrom = "youremail@server.com"
    $EmailTo = "youremail@server.com"
    $Creds = Get-Credential -UserName $EmailFrom

    $Subject = “Your subject text here”
    $Body = "Your drive has {0}GB of free space left" -f $FreeSpace

    $SMTPServer = “smtp.yourserver.com”
    $SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
    $SMTPClient.EnableSsl = $true
    $SMTPClient.Credentials = New-Object System.Net.NetworkCredential($Creds.UserName, $Creds.Password)
    $SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)
    $SMTPClient.Dispose()
}

You can also implement try-catch on the $SMTPClient.Send line if you would like to check whether the email has been sent. Tested with smtp.outlook.com.
