It just fell back on, that in the Magento backend under customer > Customers can be seen online a nice list of shop visitors, However, earlier, the last URL was displayed, visited the respective user currently. From Magento 1.9 but not this happens automatically. For this one must under System > Configuration > Advanced / System / Log in “Enable Log” of “Visitors only” on “Yes” provide.
Furthermore, it is worthwhile to put on as short as possible to store the logs. Thus, the database is not unnecessarily inflated.
Used in Magento Version 1.9 Comments? Additions? Notes? Gladly!
