windows - 当多个服务器上的多个服务停止时，Powershell 邮件警报

问题描述

每当从多个服务器停止多个服务时，我都会尝试接收单个邮件警报。如果有停止的服务，我制作了一个邮件函数以在循环中调用它。我制作的脚本有效，但它为每个停止的服务发送多封邮件，因为它在循环中......

知道如何在一封邮件中编译所有详细信息吗？


#Clear values in variable in case report needs to be re-run to avoid duplicate info on the html report 
Clear-Variable -Name "Body"
Clear-Variable -Name "Body1" 
Clear-Variable -Name "serviceslist"
Clear-Variable -Name "service"
Clear-Variable -Name "machines"
Clear-Variable -Name "server"

Function SendMailFromPowershell () { 

Get-Service -Name $service -ComputerName $server | Select MachineName, Name, DisplayName, Status, StartType | Sort-Object Name | ConvertTo-Html -Head $Header | Out-File -FilePath ".\report.html"


 $Body1 = "<br><h2>Please ensure all services are stopped before cleanup</h2><br>"
 $Body1 += Get-Content (".\report.html")
 
$Body = Out-String -InputObject $Body1 #( This basically converts the Sysytem.Object to System.String) 

$SMTPServer = "prodsmtp.ncc.local" 
$EmailFrom = "Daily_Report@ncc.local"  
$EmailTo = @('noc ncc <noc@ncc.com>')


$EmailSubject = "IISServices on $(Get-Date -Format "yyyy-MM-dd")" 

Send-MailMessage  -SmtpServer $SMTPServer -From $EmailFrom -To $EmailTo -Subject $EmailSubject  -Body $body -BodyAsHtml

解决方案

感谢您解释您需要发送一封电子邮件，其中包含仍在运行的服务。
保持大部分功能体完好无损，我会这样做：

# changed the function name to comply with the PowerShell Verb-Noun naming convention
