A UDP Only Syslog transport for [winston].


  $ npm install winston 
  $ npm install winston-syslogudp


This module is based on winston-syslog and syslogUdp and intended to provide a lightweight UDP only winston syslog transport. It was created when the authors experienced challenges with winston-syslog and with winston-loggly.


To use the Syslog transport in [winston], you simply need to require it and then either add it to an existing [winston] logger or pass an instance to a new [winston] logger:

  var winston = require('winston');
  winston.add(winston.transports.Syslog, options);


  • host: The host running syslogd, defaults to localhost.
  • port: The port on the host that syslog is running on, defaults to syslogd's default port.
  • pid: PID of the process that log messages are coming from (Default
  • facility: Syslog facility to use (Default: local0).
  • localhost: Host to indicate that log messages are coming from (Default: localhost).
  • type: The type of the syslog protocol to use (Default: BSD).

Metadata: Logged as string compiled by [glossy].

Log Levels

Because syslog only allows a subset of the levels available in [winston], levels that do not match will be ignored. Therefore, in order to use winston-syslogudp effectively, you should indicate to [winston] that you want to use the syslog levels:

  var winston = require('winston');

The Syslog transport will only log to the level that are available in the syslog protocol. These are (in increasing order of severity):

  • debug
  • info
  • notice
  • warning
  • error
  • crit
  • alert
  • emerg
