Apache capacity planning tool?

Is there any tool specially designed to analyze Apache traffic logs and give some advices on future load (bandwidth & requests per second)?

I am searching for some tools to help me understand better how the server is used and where the performance bottleneck will appear.

From stackoverflow

• There's Webalizer. As for it giving advice, I don't know. But it's a start.

• I have found a nice tool for this. It's not exactly what I want but it's ok for now.

  You can find it at the following page:

• Hi,

  I was searching for something similar to that too and I found apachetop:

  official site: http://www.webta.org/projects/apachetop/

  how to use and example: http://www.howtogeek.com/howto/ubuntu/monitor-your-website-in-real-time-with-apachetop/

  I haven't used it yet, but I hope it helps you.

  EDIT:

  Another alternative: mod_status. Which looks like is the one used by WHM/cpanel to display current apache requests, etc: http://www.debian-administration.org/articles/161

  Andrei Savu : I am already using apachetop. It's a nice tool if you want to have a live look at server activity. What I need is a tool to help me see server activity ( request per second and bandwidth usage ) back in time.
