Observability at scale: Monitoring Shiny Applications with OpenTelemetry
💬 Speaker(s): Barret Schloerke
📝 Abstract:
Understanding what happens behind the scenes in production Shiny applications has always been challenging. When users experience slow response times or unexpected behavior, developers are left guessing where bottlenecks occur. This talk introduces OpenTelemetry integration for Shiny for R, a new approach to profiling code and understanding application behavior.
Through a chat-enabled weather application, we'll explore how complex user interactions trigger cascading events across multiple processes. You'll learn how OpenTelemetry's "high-quality, ubiquitous, and portable telemetry" can provide complete visibility into your Shiny application's performance with minimal setup... just a few environment variables!
After walking through the chat app, you'll have a taste of how to implement comprehensive monitoring for your Shiny applications in production, enabling you to proactively identify and resolve unexpected performance issues.
