Instrumenting Phoenix with Telemetry Part IV: Erlang VM Measurements with `telemetry_poller`
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 telemetry_poller library into our Phoenix app so that we can observe and report on Erlang VM Telemetry events.
Instrumenting Phoenix with Telemetry Part III: Phoenix + Ecto Telemetry Events
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 examine Phoenix and Ecto’s out-of-the-box Telemetry events and use Telemetry.Metrics to observe a wide-range of such events.
Instrumenting Phoenix with Telemetry Part II: Telemetry Metrics + Reporters
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 II we’ll use Elixir’s Telemetry.Metrics and TelemetryMetricsStatsd libraries to define and send metrics to StatsD for a given Telemetry event.
Instrumenting Phoenix with Telemetry and LiveDashboard
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.
Instrumenting Phoenix with Telemetry Part I: Telemetry Under The Hood
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
LiveView Design Patterns - LiveComponent and the Single Responsibility Principle
It’s easy to end up with an overly complex LiveView that houses lots of business rules and responsibilities. We can use Phoenix.LiveComponent to build a LiveView feature that is clean, maintainable and adherent to the Single Responsibility Principle.
