OpenSearchCon Europe 2025

This session will guide you through the process of building a complete observability stack from the ground up using raw telemetry data ingested directly into a datastore, combining a variety of open source signals including OpenTelemetry and Prometheus formats.

We’ll start by leveraging our existing telemetry for maximum effectiveness because telemetry without action is just storage. We'll delve into the aspects of creating OLAP cubes. We’ll use this data for creating insightful visualizations with tools like Perses.

Drawing from experience with proprietary and open source observability tools, we’ll then evolve our monitoring by adding application telemetry. We’ll use automations like eBPF to fully observe a massively distributed cloud database offering.

Whether you're starting from scratch or looking to enhance your existing observability infrastructure, join me to discover practical strategies that you can implement today.
