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 logging

  var log = require('logging');
