如果使用調用命令，本地腳本 output 將保存在遠程服務器上

Question

大家好，感謝您在這里提供的幫助，

我有下面的腳本，他正在檢查進程列表和 memory 然后創建一個不錯的 HTML 文件作為報告，這個腳本在我的本地機器上運行良好，一旦我添加了一個循環 + Invoke-Command 和一個 list_server.txt 來獲取列表中每個服務器的進程信息，我發現列表中每個服務器的 html 文件保存在 C:/$server?documents 中。 我想將 HTML 結果保存在我運行腳本的本地計算機中。

這是我的腳本：

$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 {
        background: #395870;

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

        font-family: Arial, Helvetica, sans-serif;

)

$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

}

還有第二個問題，如您所見，我的腳本正在為每台服務器生成一個 HTML 文件，我能否以某種方式將所有進程表不單獨放在一個 HTML 文件中，非常感謝。

Answer 1

在我看來，我永遠不會在遠程服務器上構建 HTML 報告。 但是按照您的示例代碼並給出您的“問題”（我想將 HTML 結果保存在我運行腳本的本地計算機中。）。 這就是我會做的，我也稍微增強了你的代碼。

在遠程服務器上調用命令時也不需要使用foreach循環，除非有特殊需要。 在您的示例中，我看不到一次對每台服務器進行任何特定或特定的需要。 Powershell 允許您在一組服務器上調用相同的命令，這與使用-AsJob開關后跟Wait-Job完成所有調用的情況非常相似。
