我正在尝试创建一个脚本，该脚本从客户端工作站提取相关的系统信息，并提供以下内容：
- Ping工作站以查看是否联机/脱机
- 在屏幕上显示请求的信息
- 将请求的数据转储到文件
我之所以要写主机并转储到文件，是因为我希望能够让我们服务台的任何人运行它，如果我们需要保留数据以用于历史目的，则可以拥有文件副本。我在将信息写入文件时遇到了问题，简单明了，我不知道如何做到这一点(对不起：D(这是我的代码，如果您能提供任何帮助，我们将不胜感激。非常感谢。

非常感谢您的帮助
我会使用PSCustomObject来更好地组织数据。首先，你的代码中有几个问题，你没有引用远程计算机，而是默认由你的计算机来传递你的信息，而不是他们的信息。需要说明的另一点是连通性。仅仅因为你可以ping一台机器，并不意味着你可以连接到它。
以上所述，考虑到这将被其他人使用，我将在这种情况下创建一个可重复使用的函数：
Function Get-SystemInfo {
[cmdletbinding()]
Param (
[parameter(Mandatory=$false,
ValueFromPipelineByPropertyName=$true)]
[string[]]$ComputerName = $env:COMPUTERNAME
)
Begin
{
$PSCustomObject = [PSCustomObject]@{
ComputerName = $null
Status = $null
Manufacturer = $null
Model = $null
AssetTag = $null
CPU = $null
HDDCapacity = $null
HDDSpace = $null
DiskType = $null
RAM = $null
OperatingSystem = $null
ConnectedMonitors = $null
UserloggedIn = $null
}
}
Process
{
foreach ($computer in $ComputerName)
{
try {
$PSCustomObject.ComputerName = $computer
$cimSession = New-CimSession -ComputerName $computer -ErrorAction 'Stop'
$PSCustomObject.Status = 'Online - Connected'
$computerSystem = Get-CimInstance -ClassName 'Win32_ComputerSystem' -CimSession $cimSession -Property 'Manufacturer','Model','TotalPhysicalMemory ','UserName'
$PSCustomObject.Manufacturer = $computerSystem.Manufacturer
$PSCustomObject.Model = $computerSystem.Model
$PSCustomObject.RAM = "{0:N2}" -f ($computerSystem.TotalPhysicalMemory / 1GB) + "GB"
$PSCustomObject.UserloggedIn = $computerSystem.UserName
$computerBIOS = Get-CimInstance -ClassName 'Win32_BIOS' -CimSession $cimSession
$PSCustomObject.AssetTag = $computerBIOS.SerialNumber
$computerOS = Get-CimInstance -ClassName 'Win32_OperatingSystem' -CimSession $cimSession
$PSCustomObject.OperatingSystem = $computerOS.caption + ", Service Pack: " + $computerOS.ServicePackMajorVersion
$computerCPU = Get-CimInstance -ClassName 'Win32_Processor' -CimSession $cimSession
$PSCustomObject.CPU = $computerCPU.Name
$computerHDD = Get-CimInstance -ClassName 'Win32_LogicalDisk' -CimSession $cimSession -Filter 'drivetype=3'
$PSCustomObject.HDDCapacity = "{0:N2}" -f ($computerHDD.Size / 1GB) + "GB"
$PSCustomObject.HDDSpace = "{0:P2}" -f ($computerHDD.FreeSpace / $computerHDD.Size) + " Free (" + "{0:N2}" -f ($computerHDD.FreeSpace / 1GB) + "GB)"
$computerDiskType = Get-CimInstance -ClassName 'Win32_Diskdrive' -CimSession $cimSession | Where-Object -FilterScript { $_.Model }
$PSCustomObject.DiskType = $computerDiskType.caption
$computerDisplayCount = (
Get-CimInstance -Namespace 'rootwmi' -ClassName 'WmiMonitorBasicDisplayParams' -CimSession $cimSession |
Where-Object -FilterScript { $_.Active -like "True" }
).Active.Count
$PSCustomObject.ConnectedMonitors = $computerDisplayCount
}
catch {
$PSCustomObject.Status = if (Test-Connection -ComputerName $computer -Count 1) { 'Online - Unable to Connect' } else { 'offline' }
$PSCustomObject.Manufacturer = $null
$PSCustomObject.Model = $null
$PSCustomObject.AssetTag = $null
$PSCustomObject.CPU = $null
$PSCustomObject.HDDCapacity = $null
$PSCustomObject.HDDSpace = $null
$PSCustomObject.DiskType = $null
$PSCustomObject.RAM = $null
$PSCustomObject.OperatingSystem = $null
$PSCustomObject.ConnectedMonitors = $null
$PSCustomObject.UserloggedIn = $null
}
finally {
$PSCustomObject
if ($cimSession)
{
Remove-CimSession -CimSession $cimSession -ErrorAction 'SilentlyContinue'
}
}
}
}
End { }
}
当键入Get-SystemInfo -ComputerName 'ComputerOne','ComputerTwo'时，函数变得更加方便，而不是每次都修改$computers变量。从这里，您可以通过管道连接到Out-File、Export-Csv或您选择的任何其他导出cmdlet。
