I need to audit only the user logins, but i got more information than i need (see pic bellow).

Auditing information that i dont need can decrease performance of the server. How to stop alfresco from auditing the information that i dont need?
Here are my global properties that i added
audit.enabled=true
audit.alfresco-access.enabled=true
audit.alfresco-access.sub-actions.enabled=false
audit.filter.alfresco-access.default.enabled=true
audit.filter.alfresco-access.default.user=~System;~null;.*
