使用提供的powershell脚本从远程系统检索系统信息

Question

我正在尝试创建一个脚本，从客户端工作站提取相关的系统信息，并提供以下内容：

online/offline

• Displays

• 检查工作站，以查看是否将屏幕上所请求的信息转储到

文件。

我之所以做一个写主机并将其转储到一个文件中，我希望能够让我们服务台中的任何人运行它，如果我们需要为了历史目的保留数据，我希望有一个文件副本。我很难将这些信息写到文件中，简单明了，我不知道该如何做(抱歉:D)，这是我的代码，您能提供的任何帮助都将不胜感激。谢谢!

$Computers = "COMPUTERNAME"

Clear-Host

#Sets the array for the input of any string
$Outputmessage = @()

#Runs "foreach" loop statement and sets the computer variables, and performs WMI queries based on WMI Providers
foreach ($Computer in $Computers) {
    #Perform ping test on workstation prior to checking system information
    $pingtest = Test-Connection -ComputerName $Computer -Quiet -Count 1 -ErrorAction SilentlyContinue

    if ($pingtest) {
     
        #Runs WMI queries to get computer information to output on to the screen

        $computerSystem = get-wmiobject Win32_ComputerSystem -Computer $Computer
        $computerBIOS = get-wmiobject Win32_BIOS -Computer $Computer
        $computerOS = get-wmiobject Win32_OperatingSystem -Computer $Computer
        $computerCPU = get-wmiobject Win32_Processor -Computer $Computer
        $computerHDD = Get-WmiObject Win32_LogicalDisk -ComputerName $Computer -Filter drivetype=3
        $computerDiskType = Get-WmiObject Win32_Diskdrive | Where { $_.Model } | Select caption
        $computerDisplayCount = (Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorBasicDisplayParams | where { $_.Active -like "True" }).Active.Count

                    
        #Displays on screen the system information requested translated to the below

        "-------------------------------------------------------"

        write-host "System Information for: " $computerSystem.Name -BackgroundColor DarkCyan
        ""
        "Manufacturer: " + $computerSystem.Manufacturer
        "Model: " + $computerSystem.Model
        "Asset Tag: " + $computerBIOS.SerialNumber
        "CPU: " + $computerCPU.Name
        "HDD Capacity: " + "{0:N2}" -f ($computerHDD.Size / 1GB) + "GB"
        "HDD Space: " + "{0:P2}" -f ($computerHDD.FreeSpace / $computerHDD.Size) + " Free (" + "{0:N2}" -f ($computerHDD.FreeSpace / 1GB) + "GB)"
        "Disk Type: " + $computerDiskType.caption
        "RAM: " + "{0:N2}" -f ($computerSystem.TotalPhysicalMemory / 1GB) + "GB"
        "Operating System: " + $computerOS.caption + ", Service Pack: " + $computerOS.ServicePackMajorVersion
        "Connected Monitors: " + $computerDisplayCount
        "User logged In: " + $computerSystem.UserName
        
        ""
        "-------------------------------------------------------"

        $Result = $computerSystem.Name, $computerBIOS.Model, $computerOS.SerialNumber, $computerCPU.Name, $computerHDD.Size, $computerDiskType.caption, $computerDisplayCount, $computerSystem.UserName
            
    }
    else {
        $OutputMessage += "$Computer - OFFLINE"
    }
}

$Outputmessage + $Result | Out-File -FilePath "FILE PATH" -Encoding utf8 -Append

这是屏幕上显示的输出

非常感谢你的帮助

我会选择使用PSCustomObject来更好地组织您的数据。首先也是最重要的是，您的代码中有几个问题，您没有引用远程计算机，而是默认地将信息转发给您的计算机，而不是它们的。另一点需要说明的是连通性。仅仅因为你可以平一台机器，并不意味着你可以连接到它。

有了以上所述，考虑到其他人将使用这一点，我将在本例中创建一个可重用的函数：

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 'root\wmi' -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 { }
}

当输入Get-SystemInfo -ComputerName 'ComputerOne','ComputerTwo'时，函数变得更加方便，而不是每次修改$computers变量。从这里，您可以将管道输送到Out-File、Export-Csv或您选择的任何其他导出cmdlet。
