Logging

Simple logging module for microsystems that wraps winston and continuation-local-storage.

What we ultimately wanted to achieve is to generate microservice logs that are unique, traceable, and contain enough data to act on quickly and effectively. To create these logs: * Append a unique identifier to requests as they enter the architecture. * Identify the service that generates events. * Generate events specific to each microservice as the request enters and leaves the service. * Correlate events from each microservice to create an overall view of the request.

Install

 npm install micro-logging

  var log = require('micro-logging');

  log.info('hello world');
