I NO LONGER USE THE ELK STACK AND SO THIS REPO IS NO LONGER MAINTAINED, IF ANYONE WISHES TO TAKE IT OVER PLEASE RAISE AN ISSUE

Logstash TCP Wins

Inspired by the winston-logstash module but as that isn't actively maintained and doesn't support 3.0.0 of Winston, I decided to create my own

A Transport for Winston that allows for the sending of data to the Logstash TCP input plugin

Install

npm i logstash-tcp-wins

Initialise the log transport like so:

const logger = createLogger({
    format: combine (
        label({ label: 'right meow!' }),
        timestamp(),
        prettyPrint(),
        json()
    ),
    transports: [
        new logstashTcpWins({
            level: "debug",
            port: 5000,
            json: true,
            host: "localhost",
            retryInterval: 2000,
            maxRetries: 1000,
            label: "test",
        })
    ],
    exitOnError: false
})

Set up your logstash pipeline like this:

input {
    tcp {
        codec => json
        port => 5000
    }
}


output {
    stdout { codec => rubydebug } 
    elasticsearch {
        hosts => "elasticsearch:9200"
    }
}

See the app.js file in Github for requires.

Still to-do

At the moment, the recovery from a Logstash outage relies on 60s passing after the socket has reported it's connected which is pretty poor. Working on finding a way to be able to determine and rely on the socket being properly writeable to Logstash without resorting to time period. If you've got a way, please do create a PR.
