Disclaimer

I will not maintain this anymore. There are better logging frameworks out there. Try https://github.com/winstonjs/winston or https://github.com/trentm/node-bunyan

If some still wants to maintain this, just leave me a message, I'll be happy to hand over ownership.

About

This is a syslog appender for log4js. It is a rewrite of https://www.npmjs.com/package/log4js-node-syslog. It uses ain2 (https://github.com/phuesler/ain) again since node-syslog does not work with the latest versions of node.

log4js-syslog-appender works with node versions 0.10.x, 0.11.x and 0.12.x.

Installation

npm install log4js-syslog-appender --save

Configuration

In your log4js config you can use the following configuration:

UDP

"appender": { "type": "log4js-syslog-appender", "tag": "YOUR LOG TAG", "facility": "local0", "hostname": "localhost", "port": 514, "transport": "UDP" }

Options:

  • tag: appears in front of your log message in the syslog / default: log4js
  • facility: your syslog facility / default: local0
  • hostname: hostname of your syslog server / default: localhost
  • port: port of your syslog server / default: 514
  • transport: how to connect to syslog server / default: UDP

Socket

"appender": { "type": "log4js-syslog-appender", "tag": "YOUR LOG TAG", "facility": "local0", "path": "/dev/log", "transport": "socket" }

Options:

  • tag: appears in front of your log message in the syslog / default: log4js
  • facility: your syslog facility / default: local0
  • path: path to your syslog socket / default: /dev/log
  • transport: how to connect to syslog server / default: UDP s

Example:

var log4js = require('log4js'); log4js.configure({ appenders: [ { type: 'log4js-syslog-appender', tag: 'My API', facility: 'local0', hostname: 'localhost', port: 514 } ]}); var logger = log4js.getLogger('syslog'); logger.trace('a trace message'); logger.debug('a debug message'); logger.info('an info message'); logger.warn('a warning message'); logger.error('an error message'); logger.fatal('a fatal message');

This should produce messages in your syslog similar to this:

Jan 27 17:08:12 2015-01-27T16:08:12.808Z localhost My API[52315]: [WARN] - a warning message Jan 27 17:08:12 2015-01-27T16:08:12.808Z localhost My API[52315]: [ERROR] - an error message Jan 27 17:08:12 2015-01-27T16:08:12.808Z localhost My API[52315]: [FATAL] - a fatal message

Please note! Depending on your syslog setup trace, debug and info might not appear in the syslog.

Troubleshooting

If you want to send log messages via UDP, your syslog setup must accept network sockets in order to receive messages. Most syslog implementations have UDP disabled by default.
