BEAM + Prometheus + Grafana = Observability Heaven

Learn about the importance of application/system observability and how it can impact both the engineering and business sides of the house. Also learn about some of the phenomenal community tooling that we have available to us on the BEAM and how to setup PromEx to leverage all that telemetry goodness.


The goal of this presentation is to give some background on the importance of application and system observability along with some best practices/anti-patterns. Next, we'll dive into some ecosystem observability tools available on the BEAM. Lastly we'll take PromEx for a test drive and see how easy it is to instrument our applications and extract metrics from all our telemetry supported libraries.


Anyone running production systems in Elixir who wants to step up the observability of their applications/systems.
