node-websocket-activity-monitor

Show, don't tell

Prerequisite

• node.js
• ruby - just to server static files. Can be anything
• OS which runs "iostat". Most linux and osx should be okay. Don't know about windows.
• A browser which supports HTML5 canvas

How to get this

git clone git://github.com/makoto/node-websocket-activity-monitor.git

How to setup on WebSocket supported browsers

node server/websocket-server-node.js/server.js
open client/web-socket-js/iostat-client.html # in Websocke supported browser (eg: Chromium, OSX Chrome)

How to setup on NON WebSocket supported browsers (tested on firefox, and safari)

node server/websocket-server-node.js/server.js
cd client/web-socket-js
ruby server.rb
open http://localhost:10080/iostat-client.html

• client/web-socket-js/style.css
• client/web-socket-js/server.rb
• server/websocket-server-node.js/resources/iostat.js

Others (Thanks !!)

• jquery - The Write Less, Do More, JavaScript Library
• underscore - Functional Programming Aid for Javascript. Works well with jQuery.
• RGraph - A canvas graph library based on the HTML5 canvas tag
• web-socket-js - HTML5 Web Socket implementation powered by Flash
• websocket-server-node.js - A Web Socket server for local use written in JavaScript, using node.js

NOTE: I forked websocket-server-node.js and implemented support for websocket-server-node.js

Todo

• Tidy up file structures
• Remove ruby (please someone let me know nice ways to server static files from node.js)
• Write a blog post
