Getting your application up and running may feel like the finish line - but it’s often only the first step before the real work begins. In this session we will be exploring service monitoring: how do we make sure any app we create is actually behaving as expected - or ever running properly at all? While everyone may have their preferred set of logging practices (is a few print() statements really not enough??) there are robust and universal industry standards that are becoming the norm and increasing in adoption. We will take a look at how to set up monitoring with Open Telemetry (specifically for the Python components of applications) and how to easily visualize and analyse these new data sources with Elastic. Especially in an increasingly complex and ever-shifting tech landscape, it is essential to understand tech-agnostic open-source solutions that will integrate across languages, infrastructure, vendors, or trending tooling of the month.
