Changed by Unknown Docs incorrect?
Users need the ALTER TRACE and VIEW SERVER STATE permissions to access the default trace. To add these permissions, your system administrator needs to go to each user's login (Security > Logins on the server level) and enable them under Securables.
Our DBAs gave those permissions to my account and it does not work. If our DBAs give my user account sysadmin privs, then I can see a name in Last Changed By column. We tested by adding the correct roles and refreshing the view under "Commit Changes" and it shows Unknown. Then they added sysadmin to my account, I refreshed and the Last Changed By was populated.
Are the docs wrong? Is there another permission that the user needs that is included in sysadmin but missing from the docs?
