Skipping virtually all cached items

[snicoara]

I'm hoping this isn't a simple mistake on my part but running this script on a device with administrative access and 35 separate items in the ccmcache results in only 2 being visible when the script is run. I have tried modifying the thresholds as I want it to be fairly aggressive in it's cleanup but it will not spot the remaining 33 items.

No errors logged, results below:

Any idea's what may be going on here?

Hi,

That script needs a re-write.

What types of cache items are not detected?

And what are the exact parameters you used?

I thought it may have been an age thing. In the above example the only parameter that was changed was setting the cleanupactions to all. Essentially I want to remove anything and everything that has not been referenced in the last 60 days. This script is a bit of overkill but I may end up having use for a few of the other features so would love to get it working. Running the latest version of SCCM (2111).

The items that are not seen are virtually anything. The systems I'm testing on have several packages and updates, maybe a couple applications. Doesn't seem to find any of them.

``

        ## Initialize the CCM resource manager com object
        [__comobject]$CCMComObject = New-Object -ComObject 'UIResource.UIResourceMgr'

        ## Get ccm cache info
        $CacheInfo = $($CCMComObject.GetCacheInfo().GetCacheElements())

        ## Get ccm application list
        $Applications = Get-CimInstance -Namespace 'Root\ccm\ClientSDK' -ClassName 'CCM_Application' -Verbose:$false

        ## Count the applications
        $ApplicationCount = $($Applications | Measure-Object).Count

$CacheInfo $ApplicationCount $Applications ``

Can you run this, we need to check if the number of cached apps is correct

Running this against a different device today but the same issue is occurring with the script.

It seems that the get-ciminstance line isn't returning anything when searching the clientsdk, regardless of the classname.

[Ioan-Popovici]

The Get-CimInstance -Namespace 'Root\ccm\ClientSDK' -ClassName 'CCM_Application' should return all applications deployed to the machine. Are you sure that you are running powershell as an admin?

If you say that there are applications deployed that are still in the cache they should show up here too. This is needed in order to detect if an app is still needed in the cache or not.

If a cache item is not referenced in WMI then it will be removed by the Orphaned cache cleanup but if it's in the WMI as with the ones above they will not get 'Detected'.

[Ioan-Popovici]

Can you also run this?

## Get ccm package list
$Packages = Get-CimInstance -Namespace 'Root\ccm\ClientSDK' -ClassName 'CCM_Program' -Verbose:$false

## Count the packages
$PackageCount = $($Packages | Measure-Object).Count

## Get ccm update list
$Updates = Get-CimInstance -Namespace 'Root\ccm\SoftwareUpdates\UpdatesStore' -ClassName 'CCM_UpdateStatus' -Verbose:$false

## Count the updates
$UpdateCount = $($Updates | Measure-Object).Count

$PackageCount
$UpdateCount

[snicoara]

Definitely running as admin. I've added proof below.

I'm assuming that the package model packages also show up under the application classname? We only really use packages deployed to machines, we don't really use the application model or user based deployment.

[Ioan-Popovici]

No, the packages should show the the 'CCM_Program' class. Maybe if packages do bot have a program? I need the check the CM SDK again. If you say you are using packages the package count should not be 0.

[Ioan-Popovici]

The things starting with SH should be packages and the ones with { are updates I think. Let me check and I'll get back to you
