UDPATE: This is a feature built into 6.4 now, so this is no longer really necessary. 

Pretty simple Custom Inventory Rule for the K1000 below you can use to tell if FileVault is enabled or not:


ShellCommandTextReturn(fdesetup status)

It will report whether it's on or off. Now you can make smart labels for which Mac's have it enabled and which one's do not. 

If you need instructions for how to create a custom inventory rule:

  1. From the Admin portal, click Inventory > Software
  2. From the Choose Action drop down, click New
  3. Enter a name for the rule.    
    1. In this example, I used "File Vault Encryption Status"
  4. In the Custom Inventory Rule text box, enter in the rule you want to do. 
    1. For a list of available rules, click the tiny blue question mark


BONUS! - How to make a label to see all of your Custom Inventory Rules (CIR)


When you start making more and more rules, it's hard to remember which ones you have. 
You can create a smart label that includes all of them. 

  1. From the Admin portal, click Inventory > Software
  2. Click Smart Label
  3. Without entering any criteria for the search, give the smart label a name and click Save. 
    1. I named my "S - Custom Inventory Rules"
  4. Go to Home > Label Management > Smart Labels > Click the Smart Label you created
  5. Click the Edit SQL button
  6. Replace the text for the SQL query with the below then click the Save button:

SELECT ID FROM SOFTWARE
    WHERE (SOFTWARE.IS_MANUAL='1')
      AND ((SOFTWARE.INVENTORY_RULE != ''))

      Now when you go to Software inventory and click View By > Label, and select the label you created, you will see all of you CIR's.
