HTML 到 CSV 文件转换

Question

我有以下显示远程服务器 CPU/Disk/Memory 健康检查的 PowerShell 脚本。

它没有以 HTML 格式提供输出，我使用 SMTP 选项将其发送到我的电子邮件 ID。一切正常。

当前输出：

除了 HTML 输出，我还希望将此输出保存在 CSV 文件中，以便我可以使用 MLOAD 将其加载到 Teradata 中。

请帮助我获取 CSV 文件中的输出。
我们如何将 CSV 文件中的数据加载到 Teradata，这可以使用 powershell 或批处理来完成吗？

代码：

$ServerListFile = "C:\Users\HOSDUM01\Desktop\Auto\Server_health_check\list.txt"  
$ServerList = Get-Content $ServerListFile -ErrorAction SilentlyContinue 
$Result = @()

    $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) } }
    $vol2 = Get-WmiObject -Class win32_Volume -ComputerName $computername -Filter "DriveLetter = 'E:'" |

Answer 1

$result = @()

for ($i=1; $i -lt 5; $i++) {
    $result += [PSCustomObject] @{ 
            ServerName = "$i"
            CPULoad = "$($AVGProc.Average)%"
            MemLoad = "$($OS.MemoryUsage)%"
            CDrive = "$($vol.'C PercentFree')%"
            EDrive = "$($vol2.'E PercentFree')%"
            FDrive = "$($vol3.'F PercentFree')%"
        }
}

$result | ConvertTo-Csv

Answer 2

因为 $result 已经在 csv 中包含了你想要的信息，所以它可以通过管道传输到 Export-Csv

只需在脚本末尾添加这一行：

$result | Export-Csv -Path C:\folder\health_check.csv -NoTypeInformation

没有使用过 Teradata 但已经有一个关于 csv 导入的问题：

Answer 3

您需要做的就是，附加到您的脚本中：

$Result | Export-Csv "C:\Users\HOSDUM01\Desktop\Auto\Server_health_check\Test.csv" -NoType

或您想要存储文件的任何路径

编辑出于兴趣修改了脚本。
