Pending Reboot Reporting with Orchestrator

As we are implementing the ADR in SCCM for servers, we want to know if systems are pending a reboot without having to log into every server. Thankfully, Kent Agerlund, formulated and posted this awesome solution for tracking pending reboots using a compliance rule and baseline in SCCM. It reports systems that are waiting for a reboot to a non-compliance collection.

I wanted to take this to the next level with automated reporting via email. I wrote the script below that queries the non-compliance collection in SCCM and writes the results to a .CSV file and emails that file to the appropriate IT staff. I integrated this with Orchestrator so this process becomes an automated process.

To implement this in Orchestrator, you will need to use the monitor date/time activity to schedule the execution. I have it scheduled for every day.



Next, you link a Run Program activity to run the PowerShell script.



The next activity is the Get File Status. This will check to see if the .CSV file exists. The PowerShell script will delete the old .CSV file and will not create a new one if there are no systems pending a reboot.



The next thing is to customize the link between the Get File Status and Send Email activities. This stops the Send Email from taking place if the .CSV file is not present.


Finally, the Send Email activity is executed to send an email to the appropriate IT staff with the attached .CSV file.


Here is a screenshot of my runbook.

I have included in the script an example of how to implement this in the command line. You can download the PowerShell script from my GitHub site located here.

I also wanted to say how much easier SAPIEN's PowerShell Studio made writing this script. PowerShell studio is a fantastic PowerShell editing tool that takes coding to a whole new level.

 <#  
      .SYNOPSIS  
           Reboot Report  
        
      .DESCRIPTION  
           This script will query SCCM for a list of machines pending a reboot. It will then write the list to a .CSV file.  
        
      .PARAMETER CollectionName  
           Name of the collection to query for a list of machines  
        
      .PARAMETER SCCMServer  
           Name of the SCCM Server  
        
      .PARAMETER SCCMDrive  
           Drive of the SCCM server  
        
      .PARAMETER ReportFile  
           Name of the file to write the list of systems pending a reboot.  
        
      .EXAMPLE  
           powershell.exe -file RebootReporting.ps1 -CollectionName "All Servers" -SCCMServer ACMESCCM -SCCMDrive CMG -ReportFile "PendingRebootReport.csv"
