In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part III we’ll incorporate Erlang’s

The recent release of the LiveDashboard library allows us to visualize our application metrics, performance and behavior in real-time. In this post, we’ll add LiveDashboard to our Phoenix app, examine the out-of-the-box features and take a look under the hood to understand how LiveDashboard hooks into Telemetry events in order to visualize them.
In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. In Part I we’ll start out by setting up a basic, DIY Telemetry pipeline and examining how Erlang’s Telemetry library works under the hood
It’s easy to end up with an overly complex LiveView that houses lots of business rules and responsibilities. We can use
