Elixir Application Monitoring with StatsD and Statix

To keep Elixir applications running smoothly under heavy loads, you need real-time visibility into their performance. This course introduces you to the essentials of application monitoring, showing you how to capture crucial runtime data before performance issues impact your users. You will transition from having blind spots in your production environment to confidently instrumenting your Elixir systems. Through clear written explanations and practical code examples, you will learn to track custom metrics, monitor system sockets, and structure your telemetry data for maximum observability. What you'll learn: Understand the foundational concepts of application metrics, telemetry, and the StatsD protocol; Configure Statix to establish reliable, non-blocking metric reporting within your Elixir projects; Measure system performance by tracking counters, gauges, timers, and sets; Monitor socket connections and network traffic to detect bottlenecks early; Integrate StatsD reporting with modern Elixir Telemetry pipelines for clean architecture; Apply best practices for structuring metric names and tags to ensure clear observability. The journey begins with foundational definitions of metrics and monitoring architecture before moving into configuring Statix. You will then progress through step-by-step written guides on instrumenting socket connections, tracking custom events, and organizing metrics for production-grade dashboards. This course is designed for beginner to intermediate Elixir developers looking to add monitoring and observability to their applications. No prior experience with metrics or StatsD is required. Start reading today to bring deep visibility and reliable performance tracking to your Elixir systems.
