Platform Health Viewer is my current Ruby on Rails pet project.
Once stable, it will allow users to easily collect and visualize different types of statistical data which is typically produced by internet platforms, like CPU performance, user logins, HTTP requests etc.
The main application is build on Rails, the server used for data collection is written in node.js, the web interface makes heavy use of jQuery and uses Raphaël to create SVG graphs. Mass data is saved in a SQL db, other data is stored using CouchDB.
The project’s code is hosted on Github at https://github.com/ManuelKiessling/PlatformHealthViewer.
This video is a short introduction to the current alpha version of the project. A funny voice and lots of grammatical shortcomings are included for free:
