Presenters Gregorz Michalec Ivona Skorjanc Source PromCon EU 2025 Level Up Your Prometheus Observability with Automated PR Checks 🚀💡 Hey everyone! 👋 Let’s dive into a super practical solution for ensuring best practices are followed when users are modifying your Prometheus configurations. This isn’t a polished presentation – it’s a lightning talk born from a lunch-time brainstorm, but the core ideas are incredibly valuable. 🤖 The Problem: Manual Validation is a Bottleneck 🧱 Traditionally, when users (like those on your platform observability team) create new script targets or alerting rules in Prometheus repositories, the validation process was entirely manual. 🧑‍💻 This meant a real operator had to manually review every pull request, checking for potential issues. The challenge? This was: ...

Presenters Cyrille Le Clerc Source PromCon EU 2025 Decoding the Future of Observability: The Rise of OpenTelemetry & Prometheus 🚀 Hey tech enthusiasts! 👋 Cyrille from Graphana Labs just dropped some seriously insightful knowledge about the evolving landscape of observability, and we’re here to break it down for you. Let’s dive into how OpenTelemetry is shaking things up, particularly its relationship with Prometheus – and why it’s a game-changer for anyone serious about monitoring and tracing. 💡 ...

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 Bartek Protka Source PromCon EU 2025 🤖 The Trolley Problem of Metrics: Navigating Collection Resiliency 🚀 Hey everyone! 👋 Let’s talk about a surprisingly relevant thought experiment that’s impacting how we manage our data pipelines – the Trolley Problem. It might sound a bit heavy, but it perfectly illustrates a critical challenge in collection resiliency and how we’re tackling it. 🤯 The Trolley Problem in Data Collection The classic Trolley Problem asks: if you can divert a runaway trolley to save five people, but doing so will kill one, what do you do? In the world of data collection, we’re facing a similar dilemma. Imagine your data collection system – think Prometheus, OpenTelemetry collectors, or any other metric pipeline – is nearing its memory limit. You’re staring down a massive influx of data, potentially high-cardinality data (meaning lots of unique values), and you know that processing it could lead to a crash. ...
