如果使用 invoke-command，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，它正在检查进程和内存列表，然后创建一个很好的 HTML 文件作为报告，一旦我添加了一个循环 + 调用，这个脚本在我的本地机器上运行良好-命令和 list_server.txt 获取列表中每个服务器的进程信息，我发现 html 文件保存在 C:/$server?documents 中每个服务器的列表。我想将 HTML 结果保存在我运行脚本所在的本地计算机中。

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-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 {

)  

#Getting all process

$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>"

#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

}

我还有第二个问题，正如您所看到的，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放在一个 HTML 文件中而不是分开，非常感谢。

Answer 1

在我看来，我绝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所在的本地计算机中。）。这就是我要做的，我也稍微增强了你的代码。

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，我没有看到任何特定或特定的需要一次处理每台服务器。 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.

完成所有调用时的操作非常相似

如果使用 invoke-command，本地脚本输出将保存在远程服务器上

Local script output is saved on remote server if using invoke-command
