winston-beanstalkd

A Beanstalkd transport for winston.

Motivation

To enable a log-based work queue compatible with existing logging mechanisms.

Usage

  var winston = require('winston');
  
  //
  // Requiring `winston-beanstalkd` will expose 
  // `winston.transports.Beanstalkd`
  //
  require('winston-beanstalkd').Beanstalkd;
  
  winston.add(winston.transports.Beanstalkd, options);

The Beanstalkd transport takes the following options. 'host' is required:

• silent: Boolean flag indicating whether to suppress output, defaults to false.
• host: The host running Beanstalkd, defaults to localhost.
• port: The port on the host that Beanstalkd is running on, defaults to

• tube: The name of the tube you want to log to, defaults to 'winston.log'. See beanstalkd FAQ.
• delay: See the beanstalkd FAQ.
• priority: See the beanstalkd FAQ.
• ttr: See the beanstalkd FAQ.
• levelFilter: Whether to append the logging level to the tube name to filter on log level.
• transformMessage: A custom function for transforming logged objects to a queue string, defaults to JSON.stringify().

Usage

See the examples for a logger and a watcher.

In one console, start the watcher:

  $ node examples/watch.js
Watching for logs on winston.log...

In another console, run the logger:

  $ node examples/logger.js
info:   Beanstalkd log event!
warn:   This is a warning!
error:  This is an error! code=505, anything=This is metadata
help:   Log number 0
help:   Log number 1
help:   Log number 2
help:   Log number 3
help:   Log number 4
log put to winston.log { level: 'info',
  text: '  Beanstalkd log event!',
  meta: undefined }
closing...
log put to winston.log { level: 'warn', text: '  This is a warning!', meta: undefined }
closing...
log put to winston.log { level: 'error',
  text: ' This is an error!',
  meta: { code: '505', anything: 'This is metadata' } }
closing...
log put to winston.log { level: 'help', text: '  Log number 0', meta: undefined }
closing...
log put to winston.log { level: 'help', text: '  Log number 1', meta: undefined }
closing...
log put to winston.log { level: 'help', text: '  Log number 2', meta: undefined }
closing...
log put to winston.log { level: 'help', text: '  Log number 3', meta: undefined }
closing...
log put to winston.log { level: 'help', text: '  Log number 4', meta: undefined }
closing...

Return to the watcher console and see the output from processing the log entries:
