There are plenty of statistics/analytics providers for Internet deployed software (e.g. Google Analytics), but I'm looking for an analytics tool to integrate into a LAN/intranet based web application.

I'm aware of AWStats, but I'd prefer something with a design similar to Google Analytics, where a Javascript callback can be embedded into the app and call back to an analytics server. This doesn't require any sort of extra application server configuration and access to run.

I'm thinking there's nothing available that isn't proprietary / pay-for, but I'd love to be told I'm wrong!
