RabbitMQ Appender for Log4JS

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

``bash
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().

* host - string (optional, defaults to 127.0.0.1) - the location of the rabbitmq server

* username - string (optional, defaults to guest) - username to use when authenticating connection to rabbitmq
* password - string (optional, defaults to guest) - password to use when authenticating connection to rabbitmq

The appender will use the RabbitMQ Routing model command to send the log event messages to the channel.

Example

`javascript
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' } }
});
`
