[Swift-devel] swift user map

[David Kelly]

In 0.93 and later, IP address is recorded as a part of the usage statistics. This is modeled pretty closely after the way that Globus does their usage tracking. More information about this is at http://www.ci.uchicago.edu/swift/docs/tracking_policy.php

Every night from cron a script extracts a list of IP addresses from the usage database and runs them through a geolocation database called MaxMind GeoLite City. From there I extract latitudes and longitudes and use those as plot points on Google Maps.

Some information about the accuracy of the GeoLite database is at https://www.maxmind.com/app/geolite_city_accuracy.
