We’ve had a few issues with Azure AD (!!) and the question has come up of why there isn’t any monitoring in place in SCOM for Azure AD sync. Is there an official MP for this (couldn’t see one on TechNet, which wasn’t very helpful https://social.technet.microsoft.com/Forums/en-US/cc7c8d1c-8cb4-4569-98dc-f799db5c90a9/monitoring-azure-active-directory-connect-with-scom-?forum=operationsmanagermgmtpacks). If not, has anyone rolled their own I can download?
In the link you provided there is a link to this MP.
Did you try that one? Or wasn’t it sufficient?
