磁盘空间报告的Powershell

Question

我正在尝试在所有服务器上编写用于磁盘空间报告的PowerShell。目的是使其在每天的午夜作为计划任务运行，这将导出CSV并在桌面空间不足10％时发送电子邮件，该电子邮件将包含最新CSV的附件报告。

我遇到的问题是电子邮件部分。整个代码如下！

$OldReports = (Get-Date).AddDays(-30)

    #edit the line below to the location you store your disk reports# It might also
    #be stored on a local file system for example, D:\ServerStorageReport\DiskReport

    $messageParameters = @{                        
                    Subject = "Weekly Server Storage Report"                        
                    Body = "Attached is Weekly Server Storage Report. The scipt has been amended to return only servers with free disk space less than or equal to 10%. All reports are located in \\universalexplorer.net\REPORTS\ServerStorageReports$Env:COMPUTERNAMEDiskReport\, but the most recent  is sent weekly"                   
                    From = "<[email protected]>"                        
                    To = "<[email protected]>"
                    Attachments = (Get-ChildItem "\\universalexplorer.net\REPORTS\ServerStorageReports\DiskReport_$Env:COMPUTERNAME*" | sort LastWriteTime | select -last 1)                   
                    SmtpServer = "smarthost.universalexplorer.net"                        
                }

    Get-ChildItem "\\universalexplorer.net\REPORTS\ServerStorageReports\DiskReport_$Env:COMPUTERNAME*" | `
    Where-Object { $_.LastWriteTime -le $OldReports} | `
    Remove-Item -Recurse -Force -ErrorAction SilentlyContinue  

    #Create variable for log date

    $LogDate = get-date -f yyyyMMddhhmm

    Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '3'" | 
    Select-Object -Property DeviceID, DriveType, VolumeName, 
    @{Label = "Drive Letter";Expression = {$_.DeviceID}},
    @{Label = "Total Capacity (GB)";Expression = {"{0:N1}" -f( $_.Size / 1gb)}},
    @{Label = "Free Space (GB)";Expression = {"{0:N1}" -f ( $_.Freespace / 1gb ) }},
    @{Label = 'Free Space (%)'; Expression = {"{0:P0}" -f ($_.freespace/$_.size)}} | Export-Csv -path "\\universalexplorer.net\REPORTS\ServerStorageReports\DiskReport_$Env:COMPUTERNAME'_'$logDate.csv" -NoTypeInformation

    Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '3'" | Send-MailMessage @messageParameters -BodyAsHtml | Where-Object {($_.freespace/$_.size) -le '0.1'}

这是电子邮件部分的代码片段。

Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '3'" | Send-MailMessage @messageParameters -BodyAsHtml | Where-Object {($_.freespace/$_.size) -le '0.1'}
