Incoming feed statistics

I have this funny feeling there's a tool I should know of but don't...

We aim to carry a binary-clean feed, and for the most part I think we do a 
pretty good job.  But lately I've been seeing some spikes in the incoming 
traffic logs that make me wonder if something is getting past Cleanfeed.

It's not clear what the suspicious articles are, and I'm not sure how to 
investigate them.  The obvious approach is to write some stats out with a 
newsfeeds entry, but before I hack together something myself, surely such 
a tool exists?
