This guide concerns the listening information of Infomaniak Streaming Radio that can be exported using the FTP protocol; these logs (from which the listening statistics are also derived after "cleaning" or "purification") are then automatically transferred by FTP to be processed.

Preamble

• The logs of your radio will be provided in the form of a compressed file xyz.mp3-20140805.log.gz (the log date is in the form YYYYMMDD).
• Each log starts at 04:00 Swiss time and ends at 03:59:59 the next day.
• The log is in the form ip user-identifier authuser [date-time] "request" status octets "referer" "useragent" listening-time:

  • 81.56.215.98 - - [09/Apr/2019:08:23:18 +0200] "GET /toto.mp3 HTTP/1.1" 200 1211297 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8) Gecko/2019032711 Ubuntu/8.10 (intrepid) Firefox/3.0.8" 69

  • It may happen that the log line is malformed, due to a referer that is too long, for example; this behavior of Icecast cannot be modified.
• The IP addresses in the range 84.16.67.128/25 must be ignored as they are the streaming servers.
• From the settings page on the Manager, you can request the logs of past days.
• You can also directly export them to ACPM or Mediapulse.

Process logs

The best approach is to use a regular expression like the one below:

"/^(\S+)\s(.+)\s(\S+)?\s\[((\d\d)\/([a-zA-Z]{3,3})\/(\d\d\d\d)\:(\d\d)\:(\d\d)\:(\d\d)\s\+\d\d\d\d)\]\s"GET\s\/([\-a-z0-9]{1,40}(\.)?(mp3|aac|ogg){0,1})(.*)?"\s(\d{3,3})\s(\d+)\s"(.+)"\s"(.+)"\s(\d+)$/i";

This syntax is for the PHP function preg_match and will need to be adapted if other functions/languages are used.

The function preg_match returns an array with the following significant positions:
