RSS Subscriber Analyzer

This is a simple Python script that attempts to determine how many people are subscribed to your weblog. It is definitely not 100% accurate. You feed it lines from your web server log, filtered to only show hits for your RSS feed. It reports the number of times your feed was downloaded by different users. The algorithm is very simple. If the hit is from a service like Bloglines or NewsGatorOnline, the number of subscribers they report is added to the daily total. Otherwise, we count unique (ip address, user agent) pairs. This means that the number will be underestimated if two users with the same program access your feed from the same IP. The number will be overestimated if a user accesses your feed twice in the same day from different IP addresses.


Usage is something like: grep 'index.rss' /var/log/thttpd.log | python
