Modern applications are complex, distributed, and constantly evolving, which makes effective monitoring more important than ever.

The LGTM stack (Loki, Grafana, Tempo, Mimir) provides a unified, open-source solution for logs, metrics, and traces, giving developers and operators deep visibility into system behaviour.

During this session, we’ll break down each component of the LGTM stack, explain how they work together, and walk through real-world examples of monitoring modern applications. You’ll learn how to set up end-to-end observability, visualise data with Grafana dashboards, and troubleshoot issues faster with correlated logs, metrics, and traces.
