RabbitMQ Appender for Log4JS

Push log events to a Rabbitmq MQ. Require log4js-node 2.x or later.

npm install @log4js-node/rabbitmq

If you want to be sure that all messages have been sent before your programme exits, remember to call log4js.shutdown(<callback function>).

Example

log4js.configure({
  appenders: {
    mq: {
      type: '@log4js-node/rabbitmq',
      host: '127.0.0.1',
      port: 5672,
      username: 'guest',
      password: 'guest',
      routing_key: 'logstash',
      exchange: 'exchange_logs',
      mq_type: 'direct',
      durable: true
    }
  },
  categories: { default: { appenders: ['mq'], level: 'info' } }
});
