cloudwatchtographite

AWS CloudwatchToGraphite Ruby Gem

This application will fetch a list of AWS CloudWatch metrics using the Fog library to connect to the Amazon APIs. It can parse a list of metric definitions in either JSON or YAML formats. It will take the results and submit them to a Graphite server of your choosing.
