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. ...
