Get Program Execution History from a ConfigMgr Client with PowerShell

Have you ever been in the situation where something unexpected happens on a users computer and people start pointing their fingers at the ConfigMgr admin and asking “has anyone deployed something with SCCM?” Well, I decided to write a PowerShell script to retrieve the execution history for ConfigMgr programs on a local or remote client. This gives clear visibility of when and which deployments such as applications/programs/task sequences have run on the client and hopefully acquit you (or prove you guilty!)

Program execution history can be found in the registry but it doesn’t contain the name of the associated package, so I joined that data with software distribution data from WMI to give a better view.

You can run the script against the local machine, or a remote machine if you have PS remoting enabled. You can also run it against multiple machines at the same time and combine the data if desired. I recommend to pipe the results to grid view.

Get Previous and Scheduled Evaluation Times for ConfigMgr Compliance Baselines with PowerShell

I was testing a compliance baseline recently and wanted to verify if the schedule defined in the baseline deployment is actually honored on the client. I set the schedule to run every hour, but it was clear that it did not run every hour and that some randomization was being used.

To review the most recent evaluation times and the next scheduled evaluation time, I had to read the scheduler.log in the CCM\Logs directory, because I could only find a single last evaluation time recorded in WMI.

The following PowerShell script reads which baselines are currently deployed to the local machine, displays a window for you to choose one, then basically reads the Scheduler log to find when the most recent evaluations were and when the next one is scheduled.

HTML Report for SCCM Site Component Warnings and Errors

Just a quick one 🙂

If you’re like me you are too lazy busy to regularly check the component status of an SCCM Site Server for any issues, so why not get PowerShell to do it for you?

The code below will email an html-formatted report of any site components that are currently in an error or warning status, together with the last few error or warning status messages for each component. Run it as a scheduled task or with your favorite automation tool to keep your eye on any current issues. Whether you get annoyed because you now created more work for yourself, or get happy because you can stay on top of issues in your SCCM environment, I leave to you!

The report will display the components that are marked as either critical or warning with the current number of messages:

It will then display the last x status messages for each component for a quick view of what the current issue/s are:

Run the script either on the site server or somewhere where the SCCM console is installed, and set the required parameters in the script.

Create Collections for SCCM Client Installation Failures by Error Code

Ok, so in a perfect SCCM world you would never have any SCCM client installation failures and this post would be totally unnecessary. But in the real world, you are very likely to have a number of systems that fail to install the SCCM client and the reasons can be many.

To identify such systems, it can be helpful to create collections for some of the common client installation failure codes so you can easily see and report on which type of installation failures you are experiencing and the number of systems affected.

To identify the installation failure error codes you have in your environment for Windows systems, run the following SQL query against the SCCM database:

select 
	Count(cdr.Name) as 'Count',
	cdr.CP_LastInstallationError as 'Last Installation Error Code'
from v_CombinedDeviceResources cdr
where
	cdr.CP_LastInstallationError is not null
	and cdr.IsClient = 0
	and cdr.DeviceOS like '%Windows%'
group by cdr.CP_LastInstallationError
order by 'Count' desc
Client installation error counts

Next simply create a collection for each error code using the following WQL query, changing the LastInstallationError value to the relevant error code:

select 
    SYS.ResourceID,
    SYS.ResourceType,
    SYS.Name,
    SYS.SMSUniqueIdentifier,
    SYS.ResourceDomainORWorkgroup,
    SYS.Client 
from SMS_R_System as SYS 
Inner Join SMS_CM_RES_COLL_SMS00001 as COL on SYS.ResourceID = COL.ResourceID  
Where COL.LastInstallationError = 53 
And (SYS.Client = 0  Or SYS.Client is null)

Error codes are all fine and dandy, but unless you have an error code database in your head you’ll want to translate those codes to friendly descriptions. To do that, I use a PowerShell function I created that pulls the description from the SrsResources.dll which you can find in any SCCM console installation. There’s more than one way to translate error codes though – see my blog post here. Better yet, create yourself an error code SQL database which you can join to in your SQL queries and is super useful for reporting purposes – see my post here.

Anyway, once you’ve translated the error codes, you can name your collections with them for easy reference:

Client installation failure collections

Now comes the hard part – figuring out how to fix those errors and working through all the affected systems 😬

New Tool: Delivery Optimization Monitor

Delivery Optimization Monitor is a tool for viewing Delivery Optimization data on the local or a remote PC.

It is based on the built-in Delivery Optimization UI in Windows 10 but allows you to view data graphically from remote computers as well.

The tool uses the Delivery Optimization PowerShell cmdlets built in to Windows 10 to retrieve and display DO data, including stats and charts for the current month, performance snapshot data and data on any current DO jobs.

Requirements

  • A supported version of Windows 10 (1703 onward)
  • PowerShell 5 minimum
  • .Net Framework 4.6.2 minimum
  • PS Remoting enabled to view data from remote computers.

This WPF tool is coded in Xaml and PowerShell and uses the MahApps.Metro and LiveCharts open source libraries.

Download

Download the tool from the Technet Gallery.

Use

To use the tool, extract the ZIP file, right-click the Delivery Optimization Monitor.ps1 and run with PowerShell.

To run against the local machine, you must run the tool elevated. To do so, create a shortcut to the ps1 file. Edit the properties of the shortcut and change the target to read:

PowerShell.exe -ExecutionPolicy Bypass -File “<pathtoPS1file>”

Right-click the shortcut and run as administrator, or edit the shortcut properties (under Advanced) to run as administrator.

For completeness, you can also change the icon of the shortcut to the icon file included in the bin directory.

Delivery Optimization Statistics

There are 3 tabs – the first displays DO data for the current month together with charts for download and upload statistics.

The second tab displays PerfSnap data and the third displays any current DO jobs.

Create Disk Usage Reports with PowerShell and WizTree

Recently I discovered a neat little utility called WizTree, which can be used to report on space used by files and folders on a drive. There are many utilities out there that can do that, but this one supports running on the command line which makes it very useful for scripting scenarios. It also works extremely quickly because it uses the Master File Table on disk instead of the slower Windows / .Net methods.

I wanted to create a disk usage report for systems that have less than 20GB of free space – the recommended minimum for doing a Windows 10 in-place upgrade – so that I can easily review it and identify files / folders that could potentially be deleted to free space on the disk. I wanted to script it so that it can be run in the background and deployed via ConfigMgr, and the resulting reports copied to a server share for review.

The following script does just that.

First, it runs WizTree on the command line and generates two CSV reports, one each for all files and folders on the drive. Next, since the generated CSV files contain sizes in bytes, the script imports the CSVs, converts the size data to include KB, MB and GB, then outputs to 2 new CSV files.

The script then generates 2 custom HTML reports that contain a list of the largest 100 files and folders, sorted by size.

Next it generates an HTML summary report that shows visually how much space is used on the disk and tells you how much space you need to free up to drop under the minimum 20GB-free limit.

Finally, it copies those reports to a server share, which will look like this:

fs

The Disk Usage Summary report will look something like this:

dus

And here’s a snippet from the large directories and files reports:

ld

lf

There are also CSV reports which contain the entire list of files and directories on the drive:

csv

To use the script, simply download the WizTree Portable app, extract the WizTree64.exe and place it in the same location as the script (assuming 64-bit OS).  Set the run location in the script (ie $PSScriptRoot if calling the script, or the directory location if running in the ISE), the temporary location where it can create files, and the server share where you want to copy the reports to. Then just run the script in admin context.
