Ka Log Analyzer (which is in beta stage, as well as the documentation) is a tool for analyzing server's log files. You can view the result by providing 'context' and 'filters' dynamically. You can view for example:

* accessed file of certain type/in certain folder(s), from certain referrers, accessed by given IP(s) only.
* referrers to images only,
* IP(s) which accessed only given file(s)

You can then sort the result by file/referrer/hits/unique hits/ and so on.
