UNIX for Dummies Questions & Answers

Hello everybody,
I'm hosting several websites on the same server using apache virtual hosting:

Code:

~$ tail /etc/apache2/sites-available/default
<VirtualHost *>
    ServerName website1.mydomain.com
    DocumentRoot /var/www/website1
</VirtualHost>

<VirtualHost *>
    ServerName website2.mydomain.com
    DocumentRoot /var/www/website2
</VirtualHost>

1) I'm looking for a simple program that would give me basic traffic analysis on every website. Do you have any piece of advice? I almost just need to know the traffic generated by each website.

2) I'm very beginner in hosting my own websites. What are the crucial requirements that need to be wisely choosen and possibly analyzed and compared between websites? ram? cpu? bandwidth?

Thanks for your help.

look into google analytics for traffic monitoring

Google Analytics

Also check out awstats:
AWStats - Free log file analyzer for advanced statistics (GNU GPL).

Interesting... Thanks Ikon.
The problem is that starting from now, all websites on my server will not be mine and I cannot require other webmasters to run google analytics. I need an external* tool to be able to rate the usage made by every website of the server ressources so I can fairly share the costs among us.

* external from websites but obviously internal of the server

Thanks jimbalaya but I still cannot compare the usage of each hosted website.

Sorry i missed that. I use WHM for my website clients. It has views that show bandwidth and disk usage. If you have root access i suppose you could configure it. Not sure though as it came standard with my VPS package.

How about this mod to awstats:
