Today we will continue exploring techniques for debugging and tracing Elixir code that are so important for running and understanding production systems. In the past, we have discussed: how to debug your application how to trace systems with Erlyberly how to use the observer to introspect applications. The examples above always connected to systems running … »

At Plataformatec, we are always learning new techniques to help our clients introspect and monitor their production systems. Last week, we saw debugging techniques in Elixir and now we will see one of many ways to do tracing in Elixir. For this post, we will use erlyberly. You can see the installation instructions in its … »
