A post script validation after Deploy-OSDcloud runs

I am trying to "validate" that Deploy-OSDCloud was "Successful". The problem is, i don't have anything to key off that tells you its ok to reboot. I thought looking for a string in the X:\windows\temp\osdcloud-logs\transcript.log would do it, but nothing seems like a good option. Having a built in validation to key off would be great. That way I can create a prompt for the technician to restart the osdcloud process or wipe and reboot. It could be as simple as a global variable that gets flipped to true. Thanks!
