Webserver Log Analysis

What types of reports do you find Useful?

[Ocean10000]

I am curious what type of reports other webmasters/seo's find useful that are generated by [Insert Favorite Webserver Log Analysis program]. I wrote my own to suit my own needs and for the challenge of doing it.

1. I find useful is where my visitors are coming from in the world.
2. What specific books or authors they were looking at when they come in and what they were looking at when they left.
3. What resolution they were running at and actual browser window size.
4. What keywords they were using to find me with and what search engine they used to find me or other referrers.
5. Browser details that can be determined via JavaScript and useragent sniffing. (Browser name, OS, version, Preferred language, etc)
6. Search engine crawling coverage, how much and how fast are the different major search engines crawling or recrawling my site.
7. What was the most requested page (author/comic) per day or selected period of time.

Two more than I have:

8. Show successfull and fail request (200, 404, etc.)
9. Slightly similar that No 4 but with your own page so that you know which page get the most click and which don't.

All these things sound good. I'd also like to know about return visits (this would need a cookie).

I use these general stats but things really get useful when I can get

8. the 100 most visited pages in any day/week/custom time period.

It's this that helps me spot the trends (which widgets are becoming popular).

Everything depends on type of the site and traffic volume. My site has about 200 pages,and 50 - 200 visit a day.
All what I need gives me a little, open code abandon-ware "Logling" by Steffen Gerlach. The most important section is "visitors history", a facility which makes log readable without imposing any kid of interpretations.
Software is in a very initial phase.
I wish, someone would like to refine it without sacrificing simplicity.
The files are not avail at www.steffengerlach.de, but I will provide the package to a programmer freely accordingly to general permissions included into the docs.

2. recursively find entry points for conversions
