First, you will need to create a table `users_online` in your database (and have access to one). Also, create at least 3 columns (id, ip and time) set as: int(11), varchar(15) and varchar(11).
Next, you need the code to appear in your page_header, you can save the code as a file, and include it; or just paste the code directly in your header.
Finally, you can add alot to this code, and use the table to show "who" is online as well.
A server can print message "warning: too many connections" if a users makes too many requests in a short period of time, then other users will not be able to view your site, this is a very common problem.
