winston3-logstash-transport

A winston@3 transport for LogStash.

This winston transport has been rewritten from both winston-logastah and winston-logstash-udp to use the new Transport behavior from winston@3.

Where possible, this has been updated to mimic the behaviors of the original modules. There are some changes that have been made to allow the transport to handle either TCP or UDP connections to LogStash, instead of being dedicated to a single transport-layer protocol.

Usage

const Winston = require('winston');
const WinstonLogStash = require('winston3-logstash-transport');

const logger = Winston.createLogger();

logger.add(new WinstonLogStash({
  mode: 'udp',
  host: '127.0.0.1',
  port: 28777
}));

logger.error('Some Error');
