An error occured in writing to the event log on machine : cannot open log for source 'Microsoft Dynamics AX - AXUtil. You may not have write access.

I got below error while upgrading to CU 11 and performing software checklist
"An error occured in writing to the event log on machine <DBServer>: cannot open log for source 'Microsoft Dynamics AX - AXUtil. You may not have write access."

to solve, you need to get the AOS service account and give access to the SQL server. I just gave admin rights and it resolved, then you can remove for security reason.
