Question

我有一个脚本用于检查远程服务器上的服务，如果服务已关闭，则发送电子邮件。但是，如果服务器在脚本运行时发生故障，则可能导致脚本运行很长时间。有没有办法加快这个过程？我希望脚本继续直到完成。任何帮助将不胜感激。此外，如果还有其他任何我可以改进的脚本，请告诉我，因为我是PowerShell的新手。谢谢！

}

#******************  Set Variables  ******************#
$erroractionpreference = "SilentlyContinue"

$servicesPath = "C:\path_to_file\services.txt"

$servers = Get-Content $serversPath

#******************  Check Services And Send E-Mail  ******************#

foreach ($service in $services) { 

foreach ($server in $servers) 
{

    #Check If Service Exist On Server
    $checkService = Get-Service -ComputerName $server -DisplayName $service

    #If The Service Exists Evaluate Status
    if($checkService)

        if ($checkService.status -notlike "Running")
        {
            #Get Server Last Boot Up Time, Set E-Mail Subject And Body, And Send E-Mail
            $OperatingSystem = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $server
            $LastBootUp = $OperatingSystem.ConvertToDateTime($OperatingSystem.LastBootUpTime)
            $eSubject = "$service DOWN on $server"
            $eBody = "$date`r`n$service DOWN on $server`r`nLast bootup time for $server is: $LastBootUp"
            sendEmail
        }
    }
}
}

在致电Get-Service之前，请检查服务器是否在线。以下将发送一个ping以查看服务器是否在线，如果不是，将跳转到$servers中的下一个项目。将其放在您拨打Get-Service的行之前。

if ((Test-Connection -computername $server -quiet -count 1) -eq $false) {
    continue;
}

服务器关闭时，Powershell get-service运行很长时间
