Thanks, Matt -Matt ----- Forwarded message from Matt Domsch <matt@xxxxxxxxxx> ----- Date: Thu, 4 Feb 2010 10:16:09 -0600 From: Matt Domsch <matt@xxxxxxxxxx> To: advisory-board@xxxxxxxxxxxxxxxxxxxxxxx Subject: Improving metrics gathering I've spent quite a bit of time over the last week fixing up the scripts that generate Fedora's worldwide user maps [1] including the worldwide map for all Fedora versions currently in use [2] as determined by yum requests for mirrorlists. One thing that's painfully obvious is that the "Unique IP addresses" method of counting the number of installations [3] is woefully under-counting the actual number of installs. Looking at a single day's worth of checkins (over 3 million), we see ~40k unique IP addresses checking in twice a day, another 40k checking in between 4x/day and up to say 20x/day, and then a long tail, fairly evenly distributed, where a small number of single IPs are checking in up to 2000x/day. It takes quite a bit of effort to cause yum to make that many mirrorlist requests using a single machine and a single IP address - but it's highly likely there are 1000-2000 machines behind a NAT making those requests. [snip] To this end, I would like to see yum enhanced to provide information which we can use to more accurately count the number of installed Fedora systems. This has been discussed before, and documented on the wiki [5], but for various reasons never been acted upon. While I'll leave the implementation details to the appropriate teams, I think including some form of UUID in yum mirrorlist queries would be both appropriate, and safe.
