cd Logman
npm install
cd examples
node server.js

In another term :

node client.js

Then open your browser :

google-chrome "http://localhost:4444/#/server"

And see the realtime logs ;)

Stack

  • Redis
  • Node/Express
  • AngularJS
  • Socket.io

Standalone server

  • Timestamp all logs received
  • Store them to redis
  • Realtime web interface if enabled

API

This directly start the log server and the web interface :

var logServer = new LoggyServer({
    bind_port : 3044,             // logger port
    web_port : 4444,              // web interface port
    enableMonitoringPage : true,  // enable web interface
    enableClientSideLog : true    // enable routes for client side logging
});

Client side logging - logmanWeb.js

In order to log client side messages you must include logmanWeb.js in your pages. Messages are sent to the Logman server via JSONP, it doesn't need jQuery or other dependencies.

JSONP permits you to log events from web applications that runs under different domain names.

API

When you include logmanWeb.js to your web app, it directly binds logman to the window js variable.

By default window.onerror is overidded to catch all uncaught errors and send them to Logman.

--- Variables
logman.logman_url  // (str) Set the URL of the Logman server
logman.display     // (bool) Display logman logs - good for development
logman.remote(log/warn/error/exception) // Param which event should be sent to Logman

--- Methods
logman.log(msg)            // by default it just print a message
logman.warn(msg)           // send warn message to Logman
logman.error(msg)          // send error message to Logman
logman.notify(event, msg)  // send a custome event with msg to Logman

logman.monitor()           // Not implemented yet

Server side logging - logmanClient.js

Logger for server side applications, send events and custom message to Logman. Available in lib/logmanClient.js

Options

Init

var Logger = require('./path/to/logmanClient.js');

Logger.init({
   port : 3044,      // Port of the MessageBus.js server   
   ip : '127.0.0.1', // IP adress of the MessageBus.js server
   remote : true,    // Do the log should send data to MessageBus.js
   display : true    // Display log messages ? (for debug)
});

Usage

Custom events

If you want to throw custom events (user:signup for example) :

var log = require('./path/to/logmanClient.js').getCustomLogger();

// Will send { event : 'user:signup', msg : { dt : 'User alex registered' } }
log('user:signup', {dt : 'User alex registered'});

Prefixed custom events

Same event logger (TJ debug like)

If you want to use the same storage key (also a route with Messagebus.js):

var log = require('./path/to/logmanClient.js').getLogger('user:registration');

// Will send { event : 'user:registration', msg : 'User registered'}
log({msg : 'User registered'});

Express/Connect middleware logging - afflux-express.js

For documentation please reffer to : https://github.com/Alexandre-Strzelewicz/afflux-server.js

Just make sure that you use the same port for transiting the logs.
