Lightweight Open-Source APM with OTel Demo (Grafana OpenTelemetry Community Call)

We’re back with the second Grafana ❤️‍🔥OpenTelemetry Community Call!
Join us as we continue exploring how to get observability into your apps and infrastructure with Grafana, powered by OpenTelemetry.

In this session, we’ll walk through the basics of application monitoring using the OpenTelemetry Demo — a realistic example of a distributed system built on a fully open-source stack: Prometheus, Jaeger, and OpenSearch, with dashboards powered by Grafana.

We’ll cover:
🔹 Instrumentation with OpenTelemetry – how to get data flowing and what to expect
🔹 Application Performance Monitoring – RED metrics, distributed traces, and logs
🔹 Infrastructure Monitoring – CPU, memory, and Kubernetes stats
Come learn, share, and be part of shaping the OTel + Grafana journey.
