winston-posix-syslog v0.0.7

winston-posix-syslog

A Syslog transport for winston using posix.

Installation

Installing winston-syslog

  $ npm install winston
  $ npm install winston-posix-syslog

Motivation

tldr;?: The winston-syslog transport is amazing, but it only capable of communicating with syslog using udp or tcp. I needed something in my environment that uses the C bindings.

Usage

To use the PosixSyslog 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');
  var PosixSyslog = require('winston-posix-syslog').PosixSyslog;

  winston.add(PosixSyslog, options);

  winston.log('info', 'I AM the one who knocks.');

The PosixSyslog transport takes the following options:

• identity: The name of the application (Default: process.title).
• facility: Syslog facility to use (Default: local0).
• cons: Write directly to system console if there is an error while sending to system logger (Default: true).
• ndelay: Open the connection immediately (Default: true).
• pid: Include PID with each message (Default: true).
• nowait: Don't wait for child processes that may have been created while logging the message (Default: true).
• odelay: Opening of the connection is delayed until syslog() is called (Default: false).

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-posix-syslog effectively, you should indicate to winston that you want to use the syslog levels:

  var winston = require('winston');
  winston.setLevels(winston.config.syslog.levels);

The PosixSyslog 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
