PowerShell WMI/WQL 从 SCCM 获取信息 - 优化

Question

在这种情况下，我的工作正常，但我不禁觉得必须有更快的方法来做到这一点。我在这里怀疑我的结构。您是否看到可以更快地完成此操作的方法？ foreach 需要一段时间，因为它必须查询很多次。目标是拥有一个显示计算机 ($poste) 集合（名称和对象路径）的数组。

$poste = "p1234"

$SiteCode = "PRX"
$SiteServer = "SSX"

$ResourceID = Get-WmiObject -Namespace root\sms\site_$SiteCode -Computer $SiteServer -Class SMS_R_SYSTEM -Filter "Name='$poste'" |
              Select-Object -ExpandProperty ResourceID
$CollectionIDs = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class sms_fullcollectionmembership -Filter "ResourceID ='$resourceID'" |
                 Select-Object -expand CollectionID

foreach ($CollectionID in $CollectionIDs) {
    $query = @"
SELECT * FROM SMS_Collection
WHERE SMS_Collection.CollectionID='$CollectionID'
"@

[array]$CollectionNamesPath += Get-WmiObject -Namespace root\sms\site_$SiteCode -Computer $SiteServer -Query $query |
                               Select-Object name,ObjectPath |
                               Sort-Object -Property Name
} 

$CollectionNamesPath | Out-GridView

这可能是您现有代码的最简洁版本：

$poste = "p1234"
$SiteCode = "PRX"
$SiteServer = "SSX"
$ResourceID = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class SMS_R_SYSTEM -Filter "Name='$poste'" -Property ResourceID | Select-Object -ExpandProperty ResourceID
$CollectionIDs = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class sms_fullcollectionmembership -Filter "ResourceID='$resourceID'" -Property CollectionID | Select-Object -ExpandProperty CollectionID

$CollectionNamesPath = foreach ($CollectionID in $CollectionIDs) {
    $Query = "Select Name, ObjectPath From SMS_Collection Where SMS_Collection.CollectionID='$CollectionID'"
    Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Query $Query | Select-Object Name, ObjectPath | Sort-Object -Property Name
} 

$CollectionNamesPath | Out-GridView

你也可以试试这个，虽然我不确定 WQL 支持它的程度：

$poste = "p1234"
$SiteCode = "PRX"
$SiteServer = "SSX"
$ResourceID = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class SMS_R_SYSTEM -Filter "Name='$poste'" -Property ResourceID | Select-Object -ExpandProperty ResourceID
$CollectionIDs = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class sms_fullcollectionmembership -Filter "ResourceID='$resourceID'" -Property CollectionID | Select-Object -ExpandProperty CollectionID

$Query = "Select CollectionID, Name, ObjectPath From SMS_Collection Where" + $($($CollectionIDs | ForEach-Object { " SMS_Collection.CollectionID='$_' " }) -join 'or')

$CollectionNamesPath = Get-WmiObject -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Query $Query |
    Sort-Object -Property CollectionID, Name |
    Select-Object Name, ObjectPath

$CollectionNamesPath | Out-GridView

您可能能够做这样的事情：

Get-CimInstance -Namespace root\sms\site_$SiteCode -ComputerName $SiteServer -Class SMS_R_SYSTEM -Filter "Name='$poste'" -KeyOnly |
    Get-CimAssociatedInstance -ComputerName $SiteServer -ResultClassName sms_fullcollectionmembership -KeyOnly |
    Get-CimAssociatedInstance -ComputerName $SiteServer -ResultClassName SMS_Collection |
    Sort-Object -Property CollectionID, Name |
    Select-Object Name, ObjectPath

当它工作时，它太棒了。然而，根据我使用 Get-CimAssociatedInstance 的经验，充其量是一种不平衡的体验，在远程计算机上工作时更是如此。
