Question

您能否帮助我将这三个脚本组合成一种类似

的格式

ComputerName     CPUUsageAverage    MemoryUsage    C PercentFree
xxx                           12            50%              30%

我执行此操作的方式是： Get-content '.\servers.txt' | Get-CPUusageAverage

以下是脚本：

CPU

Function Get-CPUusageAverage
{
$input|Foreach-Object{Get-WmiObject -computername $_ win32_processor | Measure-Object -property LoadPercentage -Average | Select Average}
}

内存

    Function get-MemoryUsage
{
$input|Foreach-Object{
gwmi -Class win32_operatingsystem -computername $_ |
Select-Object @{Name = "MemoryUsage"; Expression = { “{0:N2}” -f ((($_.TotalVisibleMemorySize - $_.FreePhysicalMemory)*100)/ $_.TotalVisibleMemorySize) }
}
}
}

C PercentFree

Function get-CPercentFree
{
$input|ForEach-Object{
  Get-WmiObject -Class win32_Volume -ComputerName $_ -Filter "DriveLetter = 'C:'" |
  Select-object @{Name = "C PercentFree"; Expression = { “{0:N2}” -f (($_.FreeSpace / $_.Capacity)*100) } }
 } 
 }

首先我会避免使用$ input。您可以将查询组合成单个函数，然后输出带有每台计算机数据的pscustomobject，例如：

function Get-ComputerStats {
  param(
    [Parameter(Mandatory=$true, Position=0, 
               ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]
    [ValidateNotNull()]
    [string[]]$ComputerName
  )

  process {
    foreach ($c in $ComputerName) {
        $avg = Get-WmiObject win32_processor -computername $c | 
                   Measure-Object -property LoadPercentage -Average | 
                   Foreach {$_.Average}
        $mem = Get-WmiObject win32_operatingsystem -ComputerName $c |
                   Foreach {"{0:N2}" -f ((($_.TotalVisibleMemorySize - $_.FreePhysicalMemory)*100)/ $_.TotalVisibleMemorySize)}
        $free = Get-WmiObject Win32_Volume -ComputerName $c -Filter "DriveLetter = 'C:'" |
                    Foreach {"{0:N2}" -f (($_.FreeSpace / $_.Capacity)*100)}
        new-object psobject -prop @{ # Work on PowerShell V2 and below
        # [pscustomobject] [ordered] @{ # Only if on PowerShell V3
            ComputerName = $c
            AverageCpu = $avg
            MemoryUsage = $mem
            PercentFree = $free
        }
    }
  }

 cat '.\servers.txt' | Get-ComputerStats | Format-Table

Answer 2

怎么样：

cat '.\servers.txt' | % {select -property @{'n'='CPUUsageAverage';'e'={$_ | Get-CPUUsageAverage}},@{'n'='Memory Usage';'e'={$_ | Get-MemoryUsage}},@{'n'=C PercentFree';'e'={$_ | Get-CPercentFree}}}

我上一篇文章（编辑过）上面的道歉，这是我用来获取生成HTML文件的CPU，Mem和C Drive可用空间的平均值的脚本

$ServerListFile = "D:\serverList.txt"  
$ServerList = Get-Content $ServerListFile -ErrorAction SilentlyContinue 
$Result = @() 
ForEach($computername in $ServerList) 
{

$AVGProc = Get-WmiObject -computername $computername win32_processor | 
Measure-Object -property LoadPercentage -Average | Select Average
$OS = gwmi -Class win32_operatingsystem -computername $computername |
Select-Object @{Name = "MemoryUsage"; Expression = {“{0:N2}” -f ((($_.TotalVisibleMemorySize - $_.FreePhysicalMemory)*100)/ $_.TotalVisibleMemorySize) }}
$vol = Get-WmiObject -Class win32_Volume -ComputerName $computername -Filter "DriveLetter = 'C:'" |
Select-object @{Name = "C PercentFree"; Expression = {“{0:N2}” -f  (($_.FreeSpace / $_.Capacity)*100) } }

$result += [PSCustomObject] @{ 
    ServerName = "$computername"
    CPULoad = "$($AVGProc.Average)%"
    MemLoad = "$($OS.MemoryUsage)%"
    CDrive = "$($vol.'C PercentFree')%"
}
$Outputreport = "<HTML><TITLE> Server Health Report </TITLE>
                 <BODY background-color:peachpuff>
                 <font color =""#99000"" face=""Microsoft Tai le"">
                 <H2> Server Health Report </H2></font>
                 <Table border=1 cellpadding=0 cellspacing=0>
                 <TR bgcolor=gray align=center>
                   <TD><B>Server Name</B></TD>
                   <TD><B>Avrg.CPU Utilization</B></TD>
                   <TD><B>Memory Utilization</B></TD>
                   <TD><B>Drive C Free Space</B></TD>
                   </TR>"

Foreach($Entry in $Result) 

    { 
      if(($Entry.CpuLoad) -or ($Entry.memload) -ge "80") 
      { 
        $Outputreport += "<TR bgcolor=white>" 
      } 
      else
       {
        $Outputreport += "<TR>" 
      }
      $Outputreport += "<TD>$($Entry.Servername)</TD><TD align=center>$($Entry.CPULoad)</TD><TD align=center>$($Entry.MemLoad)</TD><TD align=center>$($Entry.CDrive)</TD></TR>" 
    }
 $Outputreport += "</Table></BODY></HTML>" 
    } 

$Outputreport | out-file "D:\Result $(Get-Date -Format yyy-mm-dd-hhmm).htm"
