I am doing now even more data-mining in the log files of our mirror server and in the last few weeks I have added more graphical output to the information interface of our mirror server.
The first, pretty simple, new diagram is the Disk Usage By Mirrored Project. It is created daily from a du run over the whole mirror area and then visualized using the existing code to draw a pie chart. The reason that Fedora is the largest mirrored project is due to the fact that I count all the Fedora related projects I am mirroring (fedora, archive.fedoraproject.org, secondary.fedoraproject.org) as fedora. If this diagram is now compared to the Overall Traffic Breakdown diagram it is interesting to see that there is not much difference in traffic generated by mirroring Fedora and Ubuntu, but the space required to mirror Ubuntu is much lesser. If I would know a lot more about Ubuntu I probably could start mirroring exotic Ubuntu things (just like I do with Fedora).
In addition to the new pie charts I have also created world maps on which the client distribution around the world can be seen. The code to generate the maps is based on generate-worldmap.py. With the help of this I am now able to create a world map with the client distribution for all downloads on which it can be seen that Europe is clearly the location of many (maybe even most) clients connecting to our mirror server, but also that there are basically connection coming from all over the world.
In addition to the overall map I am also creating a map for each mirrored project. It can be seen that there are mirrored projects (like Ubuntu, Fedora and OpenSUSE) which have pretty good redirectors so that only clients in the vicinity are redirected to our mirror. There are also mirrored projects (dag) which do nothing like that which results in connection from all over the world. And then there are projects which have a good redirector but do not have enough mirrors around the world like fedoraproject. What is called fedoraproject on our mirror server is a mirror of archive.fedoraproject.org (Fedora 8 and older right now, which still seems to be downloaded).
