Only the system and security administrators can configure login activity tracking and view the login activity details of other users. If you enable user login statistics, the system displays the last successful login details of the current user, the details of any failed login attempts by others, and if the current user's permissions have changed since the last login. If you use the login statistics time-period days command to set a custom time period, the system only reports the login statistics during that interval.
