Usage
Information
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
and the details of any failed login attempts by others.
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.
NOTE: Login statistics is not applicable for login sessions that do not use user names for
authentication. For example, the system does not report login activity for a telnet session that
prompts only a password field.
Example
