You could combine the users table with ci_sessions table to access the user_agent, ip_address and last_activity columns (last_activity is a timestamp, so use with from_unixtime(last_activity) to get even more info for the admin.

Tank_auth created user table should have a last_login column. You can query that to get the login times.
