Every byte has a secret. To uncover the truth, you'll dive into the mysterious world of multitenancy, one of the pillars of modern SaaS solutions. The plot thickens as a precious guitar goes missing from a residential building housing only rockers. Join Nele and Thomas on a detective mission to unravel what happened.

While investigating, you’ll learn the secrets of OpenTelemetry and explore hands-on examples of defining an observability strategy for your cloud-native applications, including how to:
- Instrument your code with OpenTelemetry;
- Manage logs, metrics, and traces via a unified API;
- Collect telemetry data using the newly graduated OTLP protocol.

However, getting visibility into multi-tenant applications requires more. You’ll discover how to add more context to the telemetry data based on the tenants, understand the difference between high-cardinality and low-cardinality values, and learn troubleshooting techniques.

Put on your detective hat and help solve the mystery.
