Good web log analyzer

[Gaby <gabi@jpost.com>]

Hi all .
In fact that here all use only russian ,I don't want to annoy and write 
on translite,so i write in english .

I search for good web log analyzer .
Wanted to know which programs "dear all " use .

Following are the requirements from a statistics program:

Reports:
- Outputs reports in HTML format
- Have the following summaries for hour, day and month:
- page views
- unique hosts
- visits (cookie based is preffered)
- 200 top visited pages
- 200 top visited directories
- hits (optional)
- visit length (optional)
- we can look page views and visitors for a specific directories (by
typing the URL)


I guess a program like this would use some sort of database (mySQL,
PostgreSQL etc).

Thanks for any suggestion .
Gabi.
