If you are saving session data into database (like described in http://ellislab.com/codeigniter/user-gui...sions.html), then you could use last_activity field to calculate online users. So if you want to find online users for last 10 minutes, you could try this:

Code:

$query = $this->db->query("SELECT COUNT(*) AS online_users FROM ci_sessions WHERE last_activity > (UNIX_TIMESTAMP() - 600)")

Note: last_activity is updated on every five minutes!
