What is the best way to monitor subscribers to my ATOM feeds

Question

I have a bunch of ATOM feeds, some generated dynamically others not, and I would like to be able to monitor the subscribers to each one.

For the dynamic ATOM feeds, it is the same php file echoing different xml dependent on the $_GET data.

Can someone tell me an efficient way to monitor the subscribers to my feeds?

Answer 1

One method would be to parse your server logs. This is easy and requires no code modification. It can also be done offline and doesn't interfere with the site. You do have server logs, right?

Alternately, add some code to the feed generation to log request data.
