•    If you want to log the login and logout timings of the users (in the selected user group), go to the User groups TSI > User groups and enable the Additional security logging field by selecting Yes. This data will be stored in the security logging file. To enable this feature, you must first make the security logging settings.
For more information, refer to Authorization > Security logging.
•    The Additional security logging setting is not enabled by default because it comes with a performance penalty. If you start logging for each user, this will create a considerable overhead. Only enable this setting if you need the information to retrieve more detailed information for analyzing issues.
