Presenters Roman Khavronenko Source PromCon EU 2025 🕵️‍♀️ Unmasking the Truth: Debugging Queries with Row Data Samples 🚀 Hey everyone! 👋 As a tech blogger, I love diving deep into the nitty-gritty of how systems work. Today, we’re tackling a surprisingly complex issue: the discrepancy between what you see in monitoring tools like Prometheus and Victoria Metrics and what’s actually happening in your database. Let’s explore how viewing row samples can be your secret weapon for troubleshooting. ...

Presenters Israel Blancas Source PromCon EU 2025 🚨 Unmasking Telemetry Trouble: Preventing Data Loss & Bottlenecks in OpenTelemetry 🚀 Let’s be honest – OpenTelemetry is amazing. The promise of automatic instrumentation, a unified observability solution – it’s almost too good to be true. But as Coral Logix’s Israel brilliantly demonstrated, chasing that “magical” automatic approach without a solid strategy can lead to a whole heap of problems. This presentation wasn’t about how to use OpenTelemetry, it was about how not to – specifically, how to avoid the common pitfalls that can turn your observability investment into a frustrating data graveyard. 💀 ...

Presenters Igor de Sousa Source PromCon EU 2025 Beyond Monitoring: The Urgent Need for True Observability 🚀 Let’s be honest, the tech world is obsessed with monitoring. We’re drowning in alerts, dashboards, and metrics – but are we really understanding what’s happening beneath the surface? This presentation challenged that very notion, arguing that true observability goes far beyond simply tracking data. Let’s dive into the key takeaways and explore a crucial shift in how we approach system health. ...

Presenters Hervé Nicol Source PromCon EU 2025 🚀 Mastering Prometheus Rules: A Deep Dive into Rule Management 💡 Let’s be honest, Prometheus rules are essential for any serious monitoring operation. But let’s also be real – managing them can feel like navigating a complex maze. How do you keep them consistent? How do you ensure they’re actually working as intended? At James Swam, we’ve been wrestling with these questions, and we’ve found some surprisingly effective strategies. Let’s break down our approach and explore some best practices. ...

Presenters Björn “Beorn” Rabenstein Source PromCon EU 2025 Rate Smoothing & Anchoring: A Deep Dive into Prometheus Rate Function Evolution 🚀 Hey everyone! 👋 Let’s talk about something that’s been buzzing in the monitoring world: the Prometheus rate function. It’s a fundamental piece of the puzzle for calculating rates from time series data, but it’s also a surprisingly complex and often misunderstood component. Today, we’re going to break down the recent changes and explore the new approaches of “anchored” and “smooth” rates – and why they matter for your observability stack. ...
