powershell - 为一个 gridview 输出运行多个测试连接

Question

如何使用多个Test-Connectioncmdlet 并将它们全部放在一个中Out-GridView，或者是否有另一种解决方案来解决我在这里尝试做的事情？关键是能够一个接一个地 ping 多个地址，并将其全部显示在同一个窗口中。

Answer 1

你可以使用这个命令：

$tests=  Test-Connection -ComputerName $env:COMPUTERNAME
$tests+= Test-Connection -ComputerName $env:COMPUTERNAME
$tests| Out-GridView

Answer 2

将您的 IP 地址（或主机名）列表输入为每个地址ForEach-Object运行的循环Test-Connection中，然后将结果通过管道传输到Out-GridView：

$addr = '192.168.1.13', '192.168.23.42', ...
$addr | ForEach-Object {
  Test-Connection $_
} | Out-GridView

请注意，这可能非常耗时，具体取决于您要检查的地址数量，因为它们都是按顺序检查的。

如果您需要加快处理大量地址的速度，例如可以将检查作为并行后台作业运行：

$addr | ForEach-Object {
  Start-Job -ScriptBlock { Test-Connection $args[0] } -ArgumentList $_
} | Out-Null

$results = do {
  $running   = Get-Job -State Running
  Get-Job -State Completed | ForEach-Object {
    Receive-Job -Job $_
    Remove-Job -Job $_
  }
} while ($running)

$results | Out-GridView

但是，过多的并行性可能会耗尽您的系统资源。根据您要检查的地址数量，您可能需要在顺序运行和并行运行之间找到一些中间立场，例如使用作业队列。

Answer 3

Test-Connection can take a array of computer names or addresses and ping them. It will return a line for each ping on each computer but you can use the -Count parameter to restrict it to 1 ping. You can also use the -AsJob to run the command as a background job.

$names = server1,server2,serverN
Test-Connection -ComputerName $names -Count 1 -AsJob | Wait-Job | Receive-Job

You will get back a list of Win32_PingStatus object that are show as

Source        Destination     IPV4Address      IPV6Address     Bytes    Time(ms) 
------        -----------     -----------      -----------     -----    -------- 

If the time column (ResponseTime property) is empty, there is no ping replay, the server is offline. You can filter on this.
