Phant
Phant is a modular node.js based data logging tool for collecting data from the Internet of Things. It is the open source software that powers data.sparkfun.com, and is actively maintained by SparkFun Electronics.
Phant is written in node.js and is very easy to install and launch a server instance
$ npm install -g phant
Start the server:
$ phant
phant http server running on port 8080
phant telnet server running on port 8081
By default Phant stores the data in text files, so is not necessary to configure anything else!
