Question

我有以下Powershell脚本来查询几个远程VM上的正常运行时间/磁盘空间/内存使用情况，但生成的结果被捆绑在一起，因为我将剩余的服务器添加到此脚本中（大约30/40多个待添加）数据开始变得不可读。

[CmdLetBinding()]
Param ( [Parameter(Mandatory=$false,Position=1)][string]$path = "C:\LON3 Web Server Report - $(get-date -f dd_MM_yyyy).html", 
        [Parameter(Mandatory=$false,Position=2)][array]$servers = @("Svr1","Svr2","Svr3")
)

Function Get-UpTime 
{ Param ([string[]]$servers) 
  Foreach ($s in $servers)  
   {  
     $os = Get-WmiObject -class win32_OperatingSystem -cn $s  
     New-Object psobject -Property @{  
       Uptime = ((get-date) - $os.converttodatetime($os.lastbootuptime)).Days 
       Hostname=$s  
         }
        }     
       } 

Function Get-DiskSpace 
{ 
 Param ([string[]]$servers) 
  Foreach ($s in $servers)  
   {  
     Get-WmiObject -Class win32_volume -cn $s |
       Select-Object @{LABEL='Server';EXPRESSION={$s}}, 
         driveletter, label,
         @{LABEL=" Total (GB)"; Expression = {" {0:N2} " -f ($_.capacity / 1GB)}}, 
         @{LABEL=" Free Space (GB) ";EXPRESSION={" {0:N2} " -f ($_.freespace/1GB)}},
         @{LABEL=" Percent Free (%) ";Expression = { "{0:N2} " -f (($_.FreeSpace / $_.Capacity)*100) }},
         @{LABEL=" Percent Usage (%) ";Expression = {" {0:N2} " -f ((($_.Capacity - $_.freespace)/$_.Capacity)*100) }}           
    }
}

Function Get-MemoryUsage 
{ 
 Param ([string[]]$servers) 
  Foreach ($s in $servers)  
   {  
     Get-WmiObject -Class win32_OperatingSystem -cn $s |
       Select-Object @{LABEL='Server';EXPRESSION={$s}}, 
         @{LABEL=" Total Physical Memory (MB) "; Expression = {" {0:N0} " -f (($_.totalvisiblememorysize / 1024))}},
         @{LABEL=" Free Physical Memory (MB) "; Expression = {" {0:N0} " -f (($_.freephysicalmemory / 1024))}},
         @{LABEL=" Total Virtual Memory (MB) "; Expression = {" {0:N0} " -f (($_.totalvirtualmemorysize / 1024))}}, 
         @{LABEL=" Free Virtual Memory (MB) "; Expression = {" {0:N0} " -f (($_.freevirtualmemory / 1024))}}     
    }
}

下面这张图片让您更容易理解。我基本上需要在每个服务器之间显示一个“新行”或“中断”（标记为“红色”行），但我无法弄清楚Powershell / HTML编码以实现此目的。

完成分离的最简单方法可能只是在每个集合的底部添加一个空对象，Will至少会在每个服务器之间提供一个换行符。所以你可以在Get-DiskSpace函数

的底部添加这样的东西

Function Get-DiskSpace 
{ 
 Param ([string[]]$servers) 
  Foreach ($s in $servers)  
   {  
     Get-WmiObject -Class win32_volume -cn $s |
       Select-Object @{LABEL='Server';EXPRESSION={$s}}, 
         driveletter, label,
         @{LABEL=" Total (GB)"; Expression = {" {0:N2} " -f ($_.capacity / 1GB)}}, 
         @{LABEL=" Free Space (GB) ";EXPRESSION={" {0:N2} " -f ($_.freespace/1GB)}},
         @{LABEL=" Percent Free (%) ";Expression = { "{0:N2} " -f (($_.FreeSpace / $_.Capacity)*100) }},
         @{LABEL=" Percent Usage (%) ";Expression = {" {0:N2} " -f ((($_.Capacity - $_.freespace)/$_.Capacity)*100) }}           
}
    [PsCustomObject]@{Server = "";driveletter = "";label = ""; "Total (GB)" = ""; "Free Space (GB)" = ""; "Percent Free (%)" = ""; "Percent Usage (%)" = ""}

}

请注意，这可能不是最佳方式，因为很难将该方法扩展到其他脚本，但它可以实现您所需的目标。
