We didn't really start taking metrics until FC6.

So here's a graph of the smolt vs yum ip stuff:

https://admin.fedoraproject.org/cacti/graph.php?action=view&rra_id=all&local_graph_id=253

The problem with the smolt numbers is that anyone doing kickstarts, 
installing via runlevel 3, yum upgrades or anaconda upgrades will never 
get prompted to enable smolt and there are privacy concerns just 
enabling it by default.  So I think the only way we can do it is start 
to seed people now, get the word out about smolt, and start monitoring 
upgrades from F7 to F8 and so on.

Adding a query string or changing the http agent on yum could also be 
useful.  It did just dawn on me that I've stopped monitoring FC6 yum 
connections and perhaps I should re-enable it.  The scary thing is I 
still regularly get requests regarding Fedora Core 1!!  (we moved it 
from the primary mirror to 
http://archives.fedoraproject.org/fedora/linux/core/1/ and that brought 
some people out of the woodwork)

I'm always open to suggestions for changes to smolt or our yum method.
