通过电子邮件发送硬盘磁盘空间警报使用Powershell

Question

我一直在浏览网页，试图找到一种方法，如果可能的话，从Gmail帐户通过电子邮件发送到共享邮箱的磁盘空间不足警报，但我正在努力与一个查询我已经拼凑起来了。

$EmailFrom = "FromEmail@Gmail.com" 
$EmailTo = "ToEmail@Gmail.com" 
$SMTPServer = "smtp.gmail.com" 
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("Username", "Password"); 
$Computers = "Local Computer" 
$Subject = "Disk Space Storage Report" 
$Body = "This report was generated because the drive(s) listed below have less than $thresholdspace % free space. Drives above this threshold will not be listed." 

[decimal]$thresholdspace = 50 

$tableFragment = Get-WMIObject -ComputerName $computers Win32_LogicalDisk ` 
| select __SERVER, DriveType, VolumeName, Name, @{n='Size (Gb)' ;e={"{0:n2}" -f ($_.size/1gb)}},@{n='FreeSpace (Gb)';e={"{0:n2}" -f ($_.freespace/1gb)}}, @{n='PercentFree';e={"{0:n2}" -f ($_.freespace/$_.size*100)}} ` 
| Where-Object {$_.DriveType -eq 3} ` 
| ConvertTo-HTML -fragment 

$regexsubject = $Body 
$regex = [regex] '(?im)<td>' 

if ($regex.IsMatch($regexsubject)) {$smtpclinet.send($fromemail, $EmailTo, $Subject, $Body)} 

脚本运行但没有任何反应，任何帮助将是太棒了！

我的版本会更长，因为我已经取代了Send-MailMessage，这样我和Send-MailMessage之间的交换就变得微不足道了。

这是一种可能的方式。对ConvertTo-Html的Fragment参数有很好的用处，但这里没有太多的理由要这样做。

这是一个脚本，预计是一个.ps1文件。强制性的东西，我真的不想硬编码超过默认设置在参数块。

param(
    [String[]]$ComputerName = $env:COMPUTERNAME, 

    [Decimal]$Theshold = 0.5, 

    [PSCredential]$Credential = (Get-Credential) 
) 

# 
# Supporting functions 
# 

# This function acts in much the same way as Send-MailMessage. 
function Send-SmtpMessage { 
    param(
     [Parameter(Mandatory = $true, Position = 1)] 
     [String[]]$To, 

     [Parameter(Mandatory = $true, Position = 2)] 
     [String]$Subject, 

     [String]$Body, 

     [Switch]$BodyAsHtml, 

     [String]$SmtpServer = $PSEmailServer, 

     [Int32]$Port, 

     [Switch]$UseSSL, 

     [PSCredential]$Credential, 

     [Parameter(Mandatory = $true)] 
     [String]$From 
    ) 

    if ([String]::IsNullOrEmtpy($_)) { 
     # I'd use $pscmdlet.ThrowTerminatingError for this normally 
     throw 'A value must be provided for SmtpServer' 
    } 

    # Create a mail message 
    $mailMessage = New-Object System.Net.Mail.MailMessage 
    # Email address formatting si validated by this, allowing failure to kill the command 
    try { 
     foreach ($recipient in $To) { 
      $mailMessage.To.Add($To) 
     } 
     $mailMessage.From = $From 
    } catch { 
     $pscmdlet.ThrowTerminatingError($_) 
    } 
    $mailMessage.Subject = $Subject 

    $mailMessage.Body = $Body 
    if ($BodyAsHtml) { 
     $mailMessage.IsBodyHtml = $true 
    } 

    try { 
     $smtpClient = New-Object System.Net.Mail.SmtpClient($SmtpServer, $Port) 
     if ($UseSSL) { 
      $smtpClient.EnableSsl = $true 
     } 
     if ($psboundparameters.ContainsKey('Credential')) { 
      $smtpClient.Credentials = $Credential.GetNetworkCredential() 
     } 

     $smtpClient.Send($mailMessage) 
    } catch {

# This is a result counter, it'll be incremented for each result which passes the threshold 
$i = 0 
# Generate the message body. There's not as much error control around WMI as I'd normally like. 
$Body = Get-WmiObject Win32_LogicalDisk -Filter 'DriveType=3' -ComputerName $ComputerName | ForEach-Object { 
    # PSCustomObject requires PS 3 or greater.
