Sane Solutions has an ISP partner program designed for that purpose. The package generates a fairly standard set of reports, among them host and domain summaries, which show where users are coming from, and a user summary, including those who log in with a user name and password. The page and path summaries give data on the most accessed pages and the paths taken to retrieve them, and the browser and platform summaries let you determine the software and operating systems your visitors are using. Because NetTracker's interface is fully interactive, it can offer drill-down capabilities. The initial reports are surface-level, and you can effectively create your own more detailed reports by digging further.
Reports offer hyperlinks that increasingly narrow the report's focus.
As an example, the top level of the ad summary displays a listing of ads and their click-through numbers and rates. The numbers for impressions and click-throughs are hyperlinked. And each of those offers drill-down links as well. You can build customized reports that let you include or exclude pages, hosts, and other details, and you can tell NetTracker to construct graphs to display the information in line, pie, bar, or 3-D format. All the reporting is done through Java, and all of it is surprisingly fast.
