Simplog v1.0.3

Simplog

Simplog is a simple logger interface for your Node.js app, exposing a convenient browser log client for when ssh isn't available.

Not meant for monitoring logs on distributed machines at this time.

Requirements

• Socket.IO
• Express
• Jade

These need to be installed alongside Simplog, and are not bundled with your install.

Installation

sudo npm install simplog

or from Git

sudo npm install https://github.com/sterlingwes/Simplog/tarball/master

Usage

var express = require('express'),
	http	= require('http'),
	app		= express(),
	server	= http.createServer(app);
	server.listen(80);
	
var	io		= require('socket.io').listen(server),
	s		= require('Simplog');

Note that on account of this issue with Connect/Express & Socket.IO, we require http vs. app.listen().

Configure express to serve simplog browser client assets:

app.configure(function() {
	app.use(express.static(__dirname + '/node_modules/Simplog/public'));
});

Initialize Simplog, referencing your log files and socket.io.

s.init({
	serverlog:	'server.log',
    errorlog:   'error.log'
}, io);

Finally, setup the route to your browser client:

app.get('/log', s.render);

Now, run your app and split your log output:

sudo node server.js 1>>server.log 2>>error.log

Try using the Simplog logger in you application:

s.log('Message'); 					// defaults to debug level 1, no label/namespace
s.log('Message',2,'MainModule'); 	// info level 2, MainModule as label
s.log('Message','MainModule'); 		// defaults to debug level
s.log('Message',3);					// error level 3, no label
console.log('Message');				// this and sys.log works fine (no formatting)

That's it! More thorough API documentation to follow.

Known Issues / To-do

• Browser client does not render exception traces gracefully
• Does not support distributed logging
• Does not detect exceptions / crashes (providing notifications)
