We have some heavy server load, and we're trying to see who are the top 50 incoming Apache connections in a given day. The catch is that this server has multiple IP addresses loaded up in Apache, multiple hostnames hosted on each IP (addon domains), and logs for each domain.
What's the trick that I can add into the Apache config temporarily so that, no matter what the IP or host is that we're hosting on a given server, we can track the top 50 incoming Apache connections for a given day?
Apache 2 is what we're using with FastCGI support.
(I'm sort of filling in for another sysop. My job is mostly PHP programmer. I'm winging this for now.)
EDIT: It seems there are many correct answers. So, I'm switching this to a community wiki.
