Meaningful Application Logging

A piece of software does not speak to us. Sometimes we would like our application to explain what is going on and why something is not working as expected. For this reason, it is essential to teach the application how to talk to us through logs.

In this chapter, we will see how to implement meaningful application logs to help us understand what is going on in our software. It is vital to monitor that everything is working as expected, as well as to keep track of what has gone wrong.

You will learn how to set up the perfect logging configuration without losing essential information. Moreover, you will discover how to avoid logging sensible data and print out only what you need.

The learning path we will cover in this chapter is as follows:

  • How to use Fastify’s logger
  • Enhancing the default logger
  • Collecting the logs
  • Managing distributed logs
