bunyan-kafka

This is a bunyan plugin for Apache Kafka. It allows you to stream your bunyan logs to Kafka. You can then forward the logs on to some other distributed processing framework, such as Elasticsearch.

Usage

The stream needs to connect to kafka, and thus we have to instantiate it asynchronously and add the stream to the logger after the ready event has been emitted. We use bunyan's addStream() API to accomplish this.

var KafkaStream = require('kafka-stream');
LOGGER = bunyan.createLogger({
    name: 'kafka-bunyan-test',
    level: bunyan.TRACE
});

var kafkaStream = new KafkaStream({
    kafka: {
        connectionString: 'localhost:2181'
    },
    topic: 'bunyan-kafka-topic'
});

kafkaStream.on('ready', function () {
    LOGGER.addStream({
        level: bunyan.INFO,
        stream: kafkaStream
    });

    // Now you can log
    LOGGER.info('Come on you target for faraway laughter, come on you stranger, you legend, you martyr, and shine!');
});

Tests

You'll need to have kafka installed locally, with zookeeper running on localhost:2818
