1. frostwoods.cc Public Transport Applications - End User Statistics Case: data.itsfactory.fi Juha Lundan, Frostwoods Oy
2. frostwoods.cc data.itsfactory.fi • data.itsfactory.fi serves various public transport related data to developers and organizations – SIRI Vehicle Monitoring • JSON, XML over HTTP – GTFS • ASCII files in ZIP archive, downloadable with browser – GTFS-RT Vehicle Positions • JSON over HTTP and Google Protocol Buffers (binary, downloadable by browser)
3. frostwoods.cc Statistics • To develop the service further, we wanted to know – How much data our server was delivering to our clients – Which data was mostly used • In addition, we were interested in – Who was using our data (broad strokes) – Were there any usage patterns • We didn't want to pay much. =)
4. frostwoods.cc Implementation • First we were thinking that we would implement custom statistics logic: use a database, record requests as they arrive etc. • However: – All our data was on top of HTTP – We were anyways using Apache to handle or proxy all our requests – Apache logs every request that comes in, so why not use that? • We ended up using AWStats
5. frostwoods.cc AWStats • Is Open Source Software, no costs to use • Reads Apache web server logs, and produces reports based on those. Has a report interface, too. – Overall request statistics – Breakdowns by time (year, month etc..), URL and countries – And a lot more • We set that up, and put it where everyone can see it. =) • http://data.itsfactory.fi/statistics/awstats.pl
6. frostwoods.cc Some figures from data.itsfactory.fi • During April 2014 – 2,9 million data requests – 36 000 unique visitors – 2300 unique visitors per day – Total amount of data requested: 113 Gigabytes • Most of the requests coming from Finland, Germany is next followed by Austria, United States and Netherlands • Usage increases during mornings and peaks during afternoon – Usage is low during nights, when only servers are awake. =)
