Server Management - Need script to monitor free space on server - windows

Question

Need script to monitor free space on server and if the free memory space goes done certain threshold send alert mail.
PS- I think the solution will be Power Shell + Windows Timer Job. I am new to Power Shell though.

Answer 1

You can get free disk space using a command like this:
([wmi]"\\$computer\root\cimv2:Win32_logicalDisk.DeviceID='$drive'").FreeSpace
And you cand send an email using the function below:
function Send-EMail
{
param (
[parameter(Mandatory = $false)][string] $EmailTo = "<Your destination email>",
[parameter(Mandatory = $false)][string] $EmailFrom = "<The sending email address>",
[parameter(Mandatory = $false)][string] $EmailSubject = "Disk space problem",
[parameter(Mandatory = $false)][string] $SMTPServer = "<your smtp server>"
)
$MailMessage = New-Object System.Net.Mail.MailMessage
$MailMessage.From = ($EmailFrom)
$MailMessage.To.Add($EmailTo)
$MailMessage.Subject = $EmailSubject
$MailMessage.Body = $EmailBody
$MailMessage.IsBodyHTML = $true
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 25)
$SMTPClient.Send($MailMessage)
}
Now combine these two functions in a PowerShell script that you can schedule with Windows scheduller.

Answer 2

You need to deal with WMI objects.

Scripting might not be necessary. If you are on Wk3 Server you can enable quota management on volumes. W2k8 has extended quota management to volume folders also.
