We are frequently using Amazon AWS EC2 servers for our customers. In order to caclulate the usage we need a tool/script which records the inbound and outbound traffic values since startup. Additionally numeric values which have to be extracted from an XML file have to be added to the statistics.
The results have to be stored/added to a CSV File in Interval (eg every 30 seconds)
It must be possible to add all necessary script files via ftp to the server, and execute them via an php script which is also stored on this server.
For testing and developing an EC2 server can be provided for a limited time of 48 hrs. You will have FTP access. If you have your own Amazon AWS Account the AMIs of the servers we use will be provided, and will give you an advantage, but this is no must.
