Modern infrastructures allow more frequent and fast deployments of applications. To deal with this ever-changing world, it becomes crucial to gain real-time visibility and detect problems as fast as possible. New tools like Prometheus are adopted more broadly but developers might be left with questions when it comes to instrumenting applications.In this talk, Simon Pasquier will do a brief introduction of the Prometheus monitoring system. He will then explain how to write good instrumentation, what are the common pitfalls and how to do effective alerting.A live demonstration will show how to get from zero instrumentation to an observable system.
