Debugging the Pipeline: Observability for Your Observability with OTel + Prometheus - Israel Blancas

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. 💀 ...

Lightning Talk: Scrape Trolley Dilemma - Bartek Protka

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. ...
