seneca-logstash-logger v1.0.0

A Seneca.js logger for Logstash

seneca-logstash-logger

• Lead Maintainer: David Gonzalez
• Sponsor: nearForm
• node: 4.x, 6.x

This module is a plugin that enables your Seneca-based microservice to send logs to Logstash via TCP or UDP.

Seneca compatibility

Supports Seneca versions 2 - 3.x

Getting Started

Here is an example on how to use the logger:

var Seneca = require('seneca')

var logstash = {
		host: 'localhost',
		port: 7132,
		type: 'udp'
}

var seneca = Seneca({legacy: {logging: false}, 'logstash-logger': logstash})
seneca.use(require('seneca-logstash-logger'))

And that's all! From now on, all the Seneca log output will be sent to the Logstash instance specified by the host property of the configuration.

Configuration

In order to configure the logger there is a number of configuration parameters that can be passed into Seneca in the key 'logstash-logger'.

Those parameters are defined by Node Logstash Client which is the library used by this module to communicate to logstash.

Running Logstash using Docker

If you need to spin up a new instance of logstash for testing purposes, the following command matches the configuration from the example above:

docker run -it --rm -p 7132:7132 logstash logstash -e 'input { udp { port => 7132} } output { stdout { } }'

Please note that if you are using docker-machine or any other virtualization technology to run Docker you will need to replace localhost by the IP of the docker-machine (just run docker-machine ip in the console).

Compatibility

seneca-logstash-logger is only compatible with Seneca 3.0+ and Node 4.x+
