What open-source software do you like for web-visible log stats? The servers are VPS, and log formats can be anything. A cron job does rollups, although the web stats program could take over that job if it wants.
The software should allow public access or private password-protected access at VPS customer discretion. Basically, we want to know what to suggest.
It should present reasonably pretty charts, monthly or annual, in HTML or XHTML.
The language could be anything but Python, PHP are favorites.
I'd like war stories with good bad and ugly, not just listings. Strong opinions are welcome.
I've only ever used AWStats. I've heard good things about Webalyzer but I'm now using Litespeed for my personal hosting needs which has a built in module for AWStats integration, making configuration a lot easier.
