如果使用调用命令，本地脚本输出将保存在远程服务器上

Question

大家好，感谢您在这里提供的帮助，

我有下面的脚本，他正在检查进程和内存列表，然后创建一个漂亮的 HTML 文件作为报告，这个脚本在我的本地机器上运行良好，一旦我添加了一个循环 + Invoke-Command 和一个 list_server。 txt 以获取列表中每个服务器的进程信息，我发现 html 文件保存在列表中每个服务器的 C:/$server?documents 中。我想将 HTML 结果保存在我运行脚本的本地机器中。

这是我的脚本：

$serversname = Get-Content -Path Server_list.text

Foreach ($servername in $serversname)

{
    invoke-command -scriptblock {

$Header = @"

<style>
h1 {

        font-family: Arial, Helvetica, sans-serif;
        color: #e68a00;
        font-size: 28px;
        text-align:center;
        margin: 0 auto;

    }

    
    h2 {

        font-family: Arial, Helvetica, sans-serif;
        color: #000099;
        font-size: 16px;
        text-align:center;
        margin: 100 auto;

    }
table {
        width:50%;
        margin-left:auto; 
        margin-right:auto;
}

table {
        font-size: 12px;
        border: 0px; 
        font-family: Arial, Helvetica, sans-serif;
    } 
    
    td {
        padding: 4px;
        margin: 0px;
        border: 0;
    }
    
    th {

        vertical-align: middle;
    }
    tbody tr:nth-child(even) {
        background: #f0f0f2;
    }
    p {

#Getting all process

$ComputerName = "<h1>Nom du serveur : $env:computername</h1>"
$ProcessInfo = Get-process  | Select-Object $properties | Sort-Object  -Property "Memory (MB)" -Descending |  ConvertTo-Html -Head $Header  -PreContent "<h2>Informations sur les processus</h2>"
$Report = ConvertTo-HTML -Body " $ComputerName $ProcessInfo" -Title "Informations sur les processus Genetec" -PostContent "<p>Date de creation : $(Get-Date)<p>"
$Report | Out-File .\log.html

#Getting only Firefox process

$ProcessInfo_firefox = Get-process firefox | Select-Object $properties | Sort-Object  -Property "Memory (MB)" -Descending |  ConvertTo-Html -Head $Header  -PreContent "<h2>Informations sur les processus Firefox</h2>"

$Report | Out-File .\log_firefox.html

#Getting only Firefox process with more than 200Mb memory 

$ProcessInfo_firefox_plus200 =  Get-Process firefox   | Select-Object @{Name="Process Name"; Expression = {$_.name}},@{Name="Memory (MB)"; Expression = {[Math]::Round(($_.WorkingSet / 1mb ),2)}} | where {$_.'Memory (MB)' -gt 300} | ConvertTo-Html -Head $Header  -PreContent "<h2>Informations sur les processus Firefox qui utilise plus que 200mb de RAM</h2>"
$Report = ConvertTo-HTML -Body " $ComputerName $ProcessInfo_firefox_plus200" -Title "Informations sur les processus Firefox qui utilise plus que 200mb de RAM" -PostContent "<p>Date de creation : $(Get-Date)<p>"
$Report | Out-File .\log_firefox_plus200.html


} -computername $servername

}

另外，我还有第二个问题，正如您所见，我的脚本正在为每个服务器生成一个 HTML 文件，我能否以某种方式将所有进程表不单独放在一个 HTML 文件中，非常感谢。

在我看来，我永远不会在远程服务器上构建 HTML 报告。但是按照您的示例代码并给出您的“问题”（我想将 HTML 结果保存在我运行脚本的本地计算机中。）。这就是我要做的，我也对你的代码做了一些改进。

在远程服务器上调用命令时也不需要使用foreach 循环，除非有特殊需要。在您的示例中，我看不到一次对每台服务器进行任何特定或特定的需要。 Powershell 允许您在一组服务器上调用相同的命令，这与使用-AsJob 开关后跟Wait-Job 完成所有调用的情况非常相似。
