如何使用 PowerCLI 获取与数据存储和数据存储集群关联的事件？

Question

这是我发布的this question 的后续，但现在遇到了枚举某些对象上的事件的问题。例如，当我运行以下代码（或尝试我之前问题中的任何解决方案）以从数据存储或数据存储集群中获取事件时：

Get-VMFolder FOLDER_NAME -Type Datastore | Get-DatastoreCluster | Get-VIEvent

对于它尝试返回的每个事件，我都遇到了以下错误：

Events can be retrieved only for inventory objects. The entity of type
'VMware.VimAutomation.ViCore.Impl.V1.DatastoreManagement.VmfsDatastoreImpl' will be ignored.

这特别烦人，因为 cmdlet 清楚地 枚举了事件，因为它尝试返回的每个事件都会出现此错误。

当我使用accepted answer 中提到的Get-TaskPlus 函数时，我之前的问题会返回不同的类型转换错误：

Cannot process argument transformation on parameter 'Entity'. Cannot convert the "DATASTORE_CLUSTER_NAME" value of type "VMware.VimAutomation.ViCore.Impl.V1.DatastoreManagement.DatastoreClusterImpl" to type "VMware.VimAutomation.ViCore.Impl.V1.Inventory.InventoryItemImpl".

如果我删除函数定义中 $Entity 参数的类型约束，错误就会消失，但我也没有得到任何结果。

我并不是真的在这里寻找建议或工具，但如果 Get-VIEvent 通过 PowerCLI 查找有关非库存对象的事件，是否有解决方法或更细微的方法来使用 PowerCLI 检索此信息？

在我发布此内容后，我进行了更多挖掘，发现 Luc Dekens 编写了另一个名为
Get-VIEventPlus 的函数。这不是开箱即用的，因为-Entity 需要VMware.VimAutomation.ViCore.Impl.V1.Inventory.InventoryItemImpl[] 类型，但数据存储和数据存储集群在VMWare.VimAutomation.ViCore.Impl.V1.DatastoreManagement 命名空间下具有不同的类型。

如果我们对 LucD 的函数进行一项更改以接受基本类型 VMware.VimAutomation.ViCore.Impl.V1.VIObjectImpl[] 而不是 InventoryItemImpl[]，则 Get-VIEventPlus 应该适用于其他 vCenter 对象类型：

function Get-VIEventPlus {
<#   
.SYNOPSIS  Returns vSphere events    
.DESCRIPTION The function will return vSphere events. With
    the available parameters, the execution time can be
   improved, compered to the original Get-VIEvent cmdlet. 
.NOTES  Author:  Luc Dekens   
.PARAMETER Entity
   When specified the function returns events for the
   specific vSphere entity. By default events for all
   vSphere entities are returned. 
.PARAMETER EventType
   This parameter limits the returned events to those
   specified on this parameter. 
.PARAMETER Start
   The start date of the events to retrieve 
.PARAMETER Finish
   The end date of the events to retrieve. 
.PARAMETER Recurse
   A switch indicating if the events for the children of
   the Entity will also be returned 
.PARAMETER User
   The list of usernames for which events will be returned 
.PARAMETER System
   A switch that allows the selection of all system events. 
.PARAMETER ScheduledTask
   The name of a scheduled task for which the events
   will be returned 
.PARAMETER FullMessage
   A switch indicating if the full message shall be compiled.
   This switch can improve the execution speed if the full
   message is not needed.   
.EXAMPLE
   PS> Get-VIEventPlus -Entity $vm
.EXAMPLE
   PS> Get-VIEventPlus -Entity $cluster -Recurse:$true
#>
 
  param(
    [VMware.VimAutomation.ViCore.Impl.V1.VIObjectImpl[]]$Entity,
    [string[]]$EventType,
    [DateTime]$Start,
    [DateTime]$Finish = (Get-Date),
    [switch]$Recurse,
    [string[]]$User,
    [Switch]$System,
    [string]$ScheduledTask,
    [switch]$FullMessage = $false
  )
 
  process {
    $eventnumber = 100
    $events = @()
    $eventMgr = Get-View EventManager
    $eventFilter = New-Object VMware.Vim.EventFilterSpec
    $eventFilter.disableFullMessage = ! $FullMessage
    $eventFilter.entity = New-Object VMware.Vim.EventFilterSpecByEntity
    $eventFilter.entity.recursion = &{if($Recurse){"all"}else{"self"}}
    $eventFilter.eventTypeId = $EventType
    if($Start -or $Finish){
      $eventFilter.time = New-Object VMware.Vim.EventFilterSpecByTime
    if($Start){
        $eventFilter.time.beginTime = $Start
    }
    if($Finish){
        $eventFilter.time.endTime = $Finish
    }
    }
  if($User -or $System){
    $eventFilter.UserName = New-Object VMware.Vim.EventFilterSpecByUsername
    if($User){
      $eventFilter.UserName.userList = $User
    }
    if($System){
      $eventFilter.UserName.systemUser = $System
    }
  }
  if($ScheduledTask){
    $si = Get-View ServiceInstance
    $schTskMgr = Get-View $si.Content.ScheduledTaskManager
    $eventFilter.ScheduledTask = Get-View $schTskMgr.ScheduledTask |
      where {$_.Info.Name -match $ScheduledTask} |
      Select -First 1 |
      Select -ExpandProperty MoRef
  }
  if(!$Entity){
    $Entity = @(Get-Folder -Name Datacenters)
  }
  $entity | %{
      $eventFilter.entity.entity = $_.ExtensionData.MoRef
      $eventCollector = Get-View ($eventMgr.CreateCollectorForEvents($eventFilter))
      $eventsBuffer = $eventCollector.ReadNextEvents($eventnumber)
      while($eventsBuffer){
        $events += $eventsBuffer
        $eventsBuffer = $eventCollector.ReadNextEvents($eventnumber)
      }
      $eventCollector.DestroyCollector()
    }
    $events
  }
}

更新：原始答案将 -Entity 类型更改为 object[]。我已更新此函数以使用 VMware.VimAutomation.ViCore.Impl.V1.VIObjectImpl[] 基本类型为 -Entity。
