Remove machines from Change Tracking and Inventory

When you're finished tracking changes on your Azure or non-Azure machines in your environment, you can stop managing them with the Change Tracking and Inventory feature. To stop managing them, you will edit the saved search query MicrosoftDefaultComputerGroup in your Log Analytics workspace that is linked to your Automation account.

To remove your machines

  1. In the Azure portal, launch Cloud Shell from the top navigation of the Azure portal. If you are unfamiliar with Azure Cloud Shell, see Overview of Azure Cloud Shell.

  2. Use the following method to identify the UUID of an Azure virtual machine or non-Azure machine that you want to remove from management.

    az vm show -g MyResourceGroup -n MyVm -d
    

  1. In the Azure portal, navigate to Log Analytics workspaces. Select your workspace from the list.

  2. In your Log Analytics workspace, select Computer Groups from the left-hand menu.

  3. From Computer Groups in the right-hand pane, the Saved groups tab is shown by default.

  4. From the table, click the icon Run query to the right of the item MicrosoftDefaultComputerGroup with the Legacy category value ChangeTracking.

  5. In the query editor, review the query and find the UUID for the VM. Remove the UUID for the VM and repeat the steps for any other VMs you want to remove.

    Note

    For added protection, before making edits be sure to make a copy of the query. Then you can restore it if a problem occurs.

    If you want to start with the original query and re-add machines in support of a cleanup or maintenance activity, copy the following query:

    Heartbeat
    | where Computer in~ ("") or VMUUID in~ ("")
    | distinct Computer
    
  6. Save the saved search when you're finished editing it by selecting Save > Save as function from the top bar. When prompted, specify the following:

    • Name: ChangeTracking__MicrosoftDefaultComputerGroup
    • Save as computer Group is selected
    • Legacy category: ChangeTracking

Note

Machines are still shown after you have unenrolled them because we report on all machines assessed in the last 24 hours. After removing the machine, you need to wait 24 hours before they are no longer listed.
