Question

我正在这里进行一个项目，而我陷入了一件事情。该项目是针对客户环境的评估过程的自动化。

这个想法是在客户环境上运行一个脚本，该脚本将从客户环境中检索许多信息，然后将其转储到xml文件中，然后稍后使用另一个脚本，读取转储的xml文件并在其中转换数据到PowerShell对象以对此数据执行分析。

检索到的数据应该以一种方式进行组织，所以我要做的是获取所有信息和数据，并将它们添加到PSCustomeObject / HashTable中，然后将其转换为xml，然后将其保存到所需的路径。

要整理我在PSCustomObject / HashTable中检索到的数据，实际上我有一个嵌套的PSCustomObject / HashTable，这使其变得更加复杂。

将要检索的数据具有不同的类型，其中一些实际上是一个csv文件，其中一些是字符串，其他是系统对象。

下面是我正在处理代码的示例。

#Get NSX Controller Config From Managing NSX Manager.
$ControllerConfig = $ContConfig

#Get NSx Controller VM vSphere Info.
$ControllerVmInfo = Get-VM -Server $vCenterServerHostingWorkingNsxControllers | Where-Object {$_.ExtensionData.moref.value -Eq $ContConfig.virtualMachineInfo.objectId}
$ControllerESXi = Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-VMHost
$ControllerCluster = Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Cluster
$ControllerDataStore = Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Datastore
$ControllerSnapShot = Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Snapshot
$ControllerClusterResources = Get-ClusterInfo -ReqVIServer $vCenterServerHostingWorkingNsxControllers -ReqCluster $ControllerCluster.Name
$ControllerVMCpuUsagePercent = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Realtime -Stat cpu.usage.average | Sort-Object Timestamp -Descending | Select-Object -First 1).Value
$ControllerVMMemUsagePercent = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Realtime -Stat mem.usage.average | Sort-Object Timestamp -Descending | Select-Object -First 1).Value
$ControllerVMUsedDiskSpace = [math]::Round(((Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name).UsedSpaceGB | Measure-Object -Sum).sum)
$ControllerCpuHistoricUsage = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Stat cpu.usage.average)
$ControllerMemoryHistoricUsage = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Stat mem.usage.average)
$ControllerVMDiskReadLatency = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Realtime -Stat virtualdisk.totalreadlatency.average)
$ControllerVMDiskWritLatency = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Realtime -Stat virtualdisk.totalwritelatency.average)
$ControllerVMMaxTotalLatency = (Get-VM -Server $vCenterServerHostingWorkingNsxControllers -Name $ControllerVmInfo.Name | Get-Stat -Stat disk.maxTotalLatency.latest)

#Get NSX Controller SSH Output.
$ControllerSSHPassword = ConvertTo-SecureString $EnvironmentInfo.NsxControllersPassword -AsPlainText -Force
$ControllerCredentials = New-Object System.Management.Automation.PSCredential ("admin", $ControllerSSHPassword)
$ControllerSSHSession = New-SSHSession -ComputerName $ContConfig.ipAddress -Credential $ControllerCredentials -AcceptKey
$ControllerClusterStatus = (Invoke-SSHCommand -SSHSession $ControllerSSHSession -Command "show control-cluster status").Output
$ControllerClusterStartupNodes = (Invoke-SSHCommand -SSHSession $ControllerSSHSession -Command "show control-cluster startup-nodes").Output
$ControllerDiskStatus = (Invoke-SSHCommand -SSHSession $ControllerSSHSession -Command "show status").Output | Where-Object {$_ -Match "\S+\s+\d+\s+\d+\s+\d+\s+(\d+)%\s(\/\S*)$"}
$ControllerUpTime = (Invoke-SSHCommand -SSHSession $ControllerSSHSession -Command "show status").Output | Where-Object {$_ -Match "Uptime"}
Remove-SSHSession -SSHSession $ControllerSSHSession | Out-Null  

#Add all retrived data in a Hash Table
$NsxControllerDataRetrival = New-Object PSObject -Property @{
    ControllerId = $ControllerConfig.id
    ControllerConfig = $ControllerConfig
    ControllervSphereInfo = New-Object PSObject -Property @{
        ControllerVmInfo = $ControllerVmInfo
        ControllerESXi = $ControllerESXi
        ControllerCluster = $ControllerCluster
        ControllerDataStore = $ControllerDataStore
        ControllerSnapShot = $ControllerSnapShot
        ControllerClusterResources = $ControllerClusterResources
        ControllerVMCpuUsagePercent = $ControllerVMCpuUsagePercent
        ControllerVMMemUsagePercent = $ControllerVMMemUsagePercent
        ControllerVMUsedDiskSpace = $ControllerVMUsedDiskSpace
        ControllerCpuHistoricUsage = $ControllerCpuHistoricUsage
        ControllerMemoryHistoricUsage = $ControllerMemoryHistoricUsage
        ControllerVMDiskReadLatency = $ControllerVMDiskReadLatency
        ControllerVMDiskWritLatency = $ControllerVMDiskWritLatency
        ControllerVMMaxTotalLatency = $ControllerVMMaxTotalLatency
    }
    ControllerSshInfo = New-Object PSObject -Property @{
        ControllerClusterStatus = $ControllerClusterStatus
        ControllerClusterStartupNodes = $ControllerClusterStartupNodes
        ControllerDiskStatus = $ControllerDiskStatus
        ControllerUpTime = $ControllerUpTime
    }
}

 ($NsxControllerDataRetrival | ConvertTo-Xml).Save($ResultFilePath + "NSX-Controller-Data-" + $EnvironmentInfo.NsxManagerFqdn + ".xml")

实际上，如果我使用PSObject并将其转换为XML，则会由于以下错误而出错，因为我需要添加深度，但是很难确定所需的深度，请记住，上面的操作会重复多次用不同的数据来提取不同的时间。

如果使用HashTable添加所有数据，然后将它们转储到XML文件中，则XML文件格式非常困难，并且在阅读时我无法弄清楚点符号或XPath查询来提取属性/元素稍后介绍xml文件。 xml文件的示例如下：

<?xml version="1.0" encoding="utf-8"?>
<Objects>
  <Object Type="System.Collections.Hashtable">
    <Property Name="Key" Type="System.String">ControllerSshInfo</Property>
    <Property Name="Value" Type="System.Collections.Hashtable">
      <Property Name="Key" Type="System.String">ControllerClusterStatus</Property>
      <Property Name="Key" Type="System.String">ControllerUpTime</Property>
      <Property Name="Value" Type="System.String">Uptime: 106 days 16 hours 43 minutes 54 seconds </Property>
      <Property Name="Key" Type="System.String">ControllerClusterStartupNodes</Property>

      </Property>
    </Property>

如果能帮助我以更简单的格式将数据转储到xml文件中，或者甚至将我指向可以执行上述操作的其他路径，我将不胜感激。

感谢您的帮助。

您是否尝试过Export-CliXml和Import-CliXml？这是为了将PS对象另存为XML并返回。

https://docs.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Utility/Export-Clixml?view=powershell-5.1

这将获取dirinfo个对象，进行导出和导入，然后转储第一个对象。

Export-Clixml -InputObject $x -path c:\temp\test.xml
$listing = Import-Clixml -Path c:\temp\test.xml
$listing[0] | gm

输出

TypeName: Deserialized.System.IO.DirectoryInfo
....

PowerShell将数据转储到xml文件中，然后稍后读取并将其转换为原始对象
