PowerShell WMI / WQL從SCCM獲取信息-優化

Question

在這種情況下，我所擁有的功能可以正常工作，但是我不禁感到必須有一種更快的方法來做到這一點。 我在這里懷疑我的結構。 您是否看到一種更快的方法？ foreach需要一段時間，因為它必須查詢很多次。 目的是要有一個數組來顯示計算機的（ $poste ）集合（名稱和對象路徑）。

$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

這可能是您現有代碼的最干凈版本：

$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

您也可以嘗試一下，盡管我不確定WQL是否支持它：

$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

您可能可以執行以下操作：

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

當它起作用時，這太棒了。 但是，以我的經驗，使用Get-CimAssociatedInstance是一種不平衡的體驗，在遠程計算機上工作時，這種感覺加倍了。
