👉 Here's a sneak peek of the agenda:

18:30: Check-in and welcome 👋

18:45: 🎙️ "The 44% Price I Paid for Observability" by Adrián Pastén, Software Engineer at ApiumHub.

I added OpenTelemetry to find performance bottlenecks in my Kubernetes PHP application. Instead, OTEL became the bottleneck - consuming 44% of my system capacity and dropping throughput from 2,519 to 1,400 requests per second. Through live metrics and real production scenarios, I'll share what auto-instrumentation actually costs, when observability tools become performance killers, and practical strategies for getting the insights you need without destroying the speed you fought for.

19:15: 🎙️ "Efficient Tail Sampling at Glovo" by Dani Medina, Principal Software Engineer at Glovo

In this insightful talk, Dani delves into how Glovo has implemented a tailored tail sampling strategy to achieve two critical objectives: keeping operational costs under control and empowering developers to identify error traces effectively.

19:45 - 20:30: Networking, Snacks, and Drinks 🍻🍕

We appreciate Glovo's generosity in hosting us at their Barcelona office and providing snacks & refreshments. Thank you so much 🙌

See you there! 👋
