Timber Hitch

A tiny module to generate a logging key, exposing the hostname, process id and an optional component name.

It is designed to be used where multiple node processes are running behind a load balancer logging to a central location.

The generated key looks like this

[orwell.local:13691]

This includes

• hostname for the process
• process id

Or this if you include a component name

[component:orwell.local:13691]

This includes

• the component name
• hostname for the process
• process id

Installation

npm install timberhitch

Usage

You can pass an optional component name if you wish to include that in your logging key.

var timberhitch = require('timberhitch');
console.log(timberhitch());

> [orwell.local:13691]

var timberhitch = require('timberhitch');
console.log(timberhitch('component'));

> [compenent:orwell.local:28984]

You can use it with any library through string concatenation.

var winston = require('winston'),
  timberhitch = require('timberhitch'),
  loggingKey = timberhitch();

winston.info(loggingKey + 'some log message');

> info: [orwell.local:13691] some log message
