The latest MirrorManager release (0.6.1) which is active since 2015-12-17 in Fedora’s infrastructure has a few additional features which provide insights into the mirror network usage.

The first is called statistics. It gives a daily overview what clients are requesting. It analysis the metalink and mirrorlist accesses and draws diagrams. Each time the local yum or dnf metadata has expired a new mirrorlist/metalink is requested which contains the ‘best’ mirrors for the client currently requesting the data. The current MirrorManager statistics implementation tries to display how often the different repositories are requested from which country for the available architectures:

• Repositories
• Countries
• Architectures

In addition to the statistics where the clients are coming from and which files they are interested in the old code to draw a map of the location of all mirror servers has been re-enabled: maps

Another new visualization tries to track the propagation. The time the existing mirrors need to carry the latest bits. A script connects to all enabled mirrors and checks which repomd.xml file is currently available on the mirror. This is done for the development branch and all active branches. The script displays how many mirrors have the current repomd.xml file or if the mirror still has the  repomd.xml file from the previous push (or the push before) or if the file is even older: Propagation.

Another relevant change in Fedora’s MirrorManager is that it is no longer possible to enter FTP URLs. This is the first step to remove FTP based URLs  as FTP based mirrors are often, depending on the network topology, difficult to connect to, other protocols (HTTP, RSYNC) are better suited and more mirror server are not providing FTP anyway.
