DB discovery issue



Please let me know how database discovery works.


which jobs find out the sql instances and deep discovery of SQL .


I found  database connection by sql , host resource and applications by wmi and db connections by wmi can discover the sql instances but unable to see deep disocvery for all


I want to know which job is responsible for deep discovery ????


Does sql user needs sysadmin permission for deep disocvery(to carry out commands on master database).



with regards,
