如何解决当多个服务器上的多个服务停止时，Powershell 邮件警报
每当多个服务器停止多个服务时，我都会尝试收到一个邮件警报。如果有停止的服务，我做了一个邮件函数来在循环中调用它。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汇总所有详细信息吗？

解决方法
感谢您解释您需要发送一封包含仍在运行的服务的电子邮件。
保持大部分函数体完好无损，我会这样做：
# changed the function name to comply with the PowerShell Verb-Noun naming convention
function Send-MailFromPowershell {
$machines = 'NPRODWEB01','NPRODWEB02'
$serviceslist = 'IISADMIN','w3logsvc','WinRM','W3SVC','WAS','NetPipeActivator','NetTcpActivator','vds','WcsPlugInService','THREADORDER'
# loop over the servers
$result = foreach ($server in $machines) {
# loop over the services in the list
foreach ($service in $serviceslist) {
try {
# try and get this service,jump to the catch block if something goes wrong
$svc = Get-Service -Name $service -ComputerName $server -ErrorAction Stop
if ($svc.Status -eq 'Running') {
Write-Warning "Service '$service' is still Running on $server"
# output an object to be collected in $result
$svc | Select-Object MachineName,Name,DisplayName,Status,StartType
}
else {
Write-Host "$service is stopped on $server" -ForegroundColor Green
}
}
catch {
Write-Warning "$server error! Please manually check on server`r`n$($_.Exception.Message)"
}
}
}
# only send an email if there is something to alert (not all services were stopped)
# the @() is needed to force $result to be an array even if it has only one item
if (@($result).Count) {
# convert the resulting array of objects into a HTML table
$table = ($result | Sort-Object MachineName,Name | ConvertTo-Html -Fragment) -join [environment]::NewLine
# create a HTML template for the email using a Here-String
$htmlTemplate = @'
<html><head>
<meta http-equiv='Content-Type' content='text/html; charset=iso-8859-1'>
<title>IIS Services</title>"
<style>
TABLE {border-width: 1px; border-style: solid; border-color: black; border-collapse: collapse;}
TH {border-width: 1px; padding: 3px; border-style: solid; border-color: black; background-color: #6495ED;}
TD {border-width: 1px; padding: 3px; border-style: solid; border-color: black;}
</style>
</head>
<body>
<h2>Please ensure all services are stopped before cleanup</h2>
<br />
@@TABLE@@
</body></html>
'@
# create a Hashtable to splat the parameters to Send-MailMessage
$mailParams = @{

To = 'noc ncc <noc@ncc.com>'
Subject = 'IISServices on {0:yyyy-MM-dd}' -f (Get-Date)
SmtpServer = 'prodsmtp.ncc.local'

}
# send the email

# call the function
