I need advice. What permissions must have an account that I use for Event collector agent on the Windows?
There is no special User to get Eventlogs. You can setup a Usergroup and give this user group the special rights to get all Eventlogs. Or you use a Domain-Admin.
The account must be part of the Event Log Readers group.
