show the busy virtual hosts

Hi All,

I have an apache server runing on CENTOS 5.x,

Server version: Apache/2.2.3

I was wondering if anyone has a solution where I could see utilization inside my apache process. I would like to see which of my virtual hosts are most busy,

Thanks in advance

If you want to see present connections you could do something like this if they're on separate ips--

Code:

netstat -plan | grep ":[443|80]" | awk '{print $4}' | sort -n | uniq -c | sort -n

If you're doing name based it's a bit harder, as you'd have to look at all the logs to determine the information.

You could also try apachetop.

There is a really cool module to watch what is going on in apache in real time. It is called mod_status. Here is a page with a quick how to. http://www.cyberciti.biz/faq/apache-server-status/
Here is what you see when you set this up.

If you have mod_status enabled you can also do a 'apachectl status' at the command line and get the same information at the prompt, or alternately 'watch -n10 apachectl status' and it'll update every 10s.
