PowerShell - 调整输出标头组

Question

所以，我有一个简单的脚本，它针对多个不同的服务器和端口运行 test-netconnection，以验证 SCCM 客户端是否具有必要的连接性。我在一开始就收集了几个变量，我静态设置了一些其他变量，因为它们不是特定于站点的，将用于所有测试。

但问题是我想在每个部分之前在屏幕上打印一个描述符，然后是输出表，只是为了让输出更容易一目了然。但它根本没有这样做，我不知道如何让它做到这一点。所以基本上我想要这样的东西：

Testing connectivity to the local distribution point
ComputerName    RemoteAddress   RemotePort        TCPTestSucceeded
--------------  -----------     ----------------  ---------------- 
DPserver        192.168.1.1     80                True

Testing Connectivity to the Management Points
ComputerName    RemoteAddress   RemotePort        TCPTestSucceeded
--------------  -----------     ----------------  ---------------- 
MPserver        192.168.1.1     80                True

但相反，我得到了这个：

Testing connectivity to the local distribution point

WARNING: TCP connect to (10.30.22.72 : 8005) failed
ComputerName                 RemoteAddress RemotePort TcpTestSucceeded
------------                 ------------- ---------- ----------------
DPserver                     10.30.22.72           80             True

Testing connectivity to the management points
MPserver1                    10.88.166.167      10123             True

部分问题是出现了错误，即使我将 -ErrorAction 设置为 SilentlyContinue，然后部分问题是标题只出现一次。我猜我必须以某种方式对结果进行分组，以使每个组的标题都出现，但我不知道该怎么做。

有人可以帮忙吗？这是我现在拥有的完整脚本（为了发布而更改了静态服务器名称）：

$DP = Read-Host -Prompt 'Input the FQDN for the local DP'
$MP1 = 'MP1'
$MP2 = 'MP2'
$MP3 = 'MP3'
$SUP1 = 'SUP1'
$SUP2 = 'SUP2'
$Client = Read-Host -Prompt 'Input the workstation to test from'

Enter-PSSession $Client

Exit-PSSession

另外，我知道我可以为某些部分执行 for-each 循环，但我想先让它按原样工作，然后再找出 for-each 循环。 （我是一个非常新手脚本编写者。）

没有错误，只有警告，您可能也想将它们静音。

在代码顶部使用下面。

$WarningPreference='SilentlyContinue'
