I wasn't able to find any feature/feature request regarding the extension of the audit log depth for new events or to increase the storage time of the audit log. However, if you'd like this type of feature to be implemented, please submit a feature request.
When it comes to monitoring traffic statistics of a user per session, you should be able to do this within Azure Active Directory under Audit logs and filtering by "Initiator/actor". If you're using O365, you can search the audit log for the specific event(s).
