Question

此PowerShell脚本非常有用，如果您在DMZ中有SQL服务器，则可以使用它来获取总容量，已用容量，可用空间和可用空间％。我使用相同的脚本来检查所有内部SQL服务器的硬盘空间。但是，当我尝试在DMZ中对我的SQL服务器运行时，会发生一件奇怪的事情。

此PowerShell脚本从名为dmzsl.txt的文件中获取SQL Server列表。当我仅使用一个SQL服务器更新dmzsl.txt文件并运行PowerShell脚本时，我会为同一服务器返回3个结果集。

我已经尝试了几种方法来解决这个问题，但我不能让它用一个数据集报告而不重复。

set-location C:\SQLServerDiskSpaceReport

$isodate=Get-Date -format s
$isodate=$isodate -replace(":","")
$basepath=(Get-Location -PSProvider FileSystem).ProviderPath

$instancepath=$basepath + "\config\dmzsl.txt"
$outputfile="\DMZServerLogs\sql_server_db_sizes_" + $isodate + ".html"
$outputfilefull = $basepath + $outputfile

$filePath = ""

$freeSpaceFileName = $outputfilefull
$warning = 30
$critical = 10
New-Item -ItemType file $freeSpaceFileName -Force

我收到一条错误消息，但我不熟悉PowerShell以了解这个错误。错误也有点含糊不清，因为你可以看到它无法验证参数＆＃39; computername＆＃39;的参数。但是它能够为同一台服务器生成3次报告。

Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The
argument is null or empty. Provide an argument that is not null or empty,
and then try the command again.

Answer 1

错误消息实际上是不言自明的。您的循环变量$server为空。检查文件$instancepath。
