It is common yet quite new to hear the term ‘Observability’. But what does that mean? Is it just another new acronym for monitoring?

In this current modern technology world where we are working with so many different types of systems - microservices, distributed system and many others which are kind of huge spider webs. Imagine while testing these distributed systems and you have no clue of what’s going on under the hood. Gone are the days where testers have to rely only testing the user interface or the api’s. I worked on a distributed system where no one had an answer to what’s going wrong whenever there was a production issue each time. We had some monitoring and logging in place but we had no clue where to look at when things went wrong on production. There was a need to have more powerful insights of the internals of the system and more than that there was a need for visibility to understand what’s happening under the hood of the system which is giving the team the superpowers to predict the future.

This is where we started first steps into ‘Observability’. In this talk, I’ll share my journey of adoption of a culture of observability within the engineering team.
