logstash tcp module for bunyan

Logstash TCP stream for Bunyan-Hub

This is a fork of chris-rock/bunyan-logstash-tcp to use with bunyan-hub. It re

install

npm i --save bunyan-hub-logstash-tcp

usage

Use with bunyan-sub-stream:

var SubStream = require('bunyan-sub-stream');
var subStream = new SubStream({
    level: 'debug',
    raw: true
});
var bunyantcp = require('bunyan-hub-logstash-tcp');
var pubStream = bunyantcp.createStream({
    host: '127.0.0.1',
    port: 9998
});
subStream.pipe(pubStream);

and you've done forwarding all events to logstash up from debug level.
