Can I count total uPortal logins over time?

Is there a way to obtain statistics of logins to uPortal or number of sessions in a given time frame (i.e. total logins to portal by fiscal year)?
In order to obtain this statistic, uPortal would need to record whenever a user login event fires, e.g. via the uPortal stats recorder API. User login is a supported statistic, so it's a matter of using a recorder implementation that say records a user-timestamp pair to a database table on every login event and then to query the database to count logins for a given time interval.

While the API supports handling this event, uPortal doesn't out of the box record each login as a separate entry to a database table, and so out of the box, this statistic is not available.
