Usage

Send an event record to Fluentd

Singleton style

var logger = require('fluent-logger')
// The 2nd argument can be omitted. Here is a defualt value for options.
logger.configure('tag', {
   host: 'localhost',  
   port: 24224,
   timeout: 3.0
});

// send an event record with 'tag.label'
logger.emit('label', {record: 'this is a log'});

Instance style

var logger = require('fluent-logger').createFluentSender('tag', {

The emit method has following signature

.emit(label string, , timestamp number/date, callback function)

Where only the record argument is required. If the label is set it will be appended to the configured tag.

Before using log4js support, you should install it IN YOUR APPLICATION.

var log4js = require('log4js');
log4js.addAppender(require('fluent-logger').support.log4jsAppender('mytag', {
   host: 'localhost',
   port: 24224,
   timeout: 3.0
}));

var logger = log4js.getLogger('foo');
logger.info('this log record is sent to fluent daemon');
