Making a Report of visitors log


i am developing y first piwik plugin and i have some issues. I want to make a report of the visitors log. The first idea was to “clone” the visitor log and make report function and the other idea was to develop a plugin completely on my own. I don´t know which one is the better idea. I know that there could be much server load with that but my website is not having much traffic (20 per day) and i need a email support of them for every day.

Did you manage to make the plugin ?
