OpenTelemetry: Fundamentals of Tracing and Observability

Need deep insight into how your distributed applications are performing? Understanding complex microservice interactions requires a unified, modern approach to observability. This course provides the foundational knowledge and practical steps needed to implement OpenTelemetry (OTEL), the vendor-neutral standard for generating, collecting, and managing telemetry data. You will emerge prepared to instrument services, diagnose performance bottlenecks, and maintain high-performing, reliable systems.What you'll learn:<ul><li>Understand the fundamental concepts of observability, including traces, metrics, and logs.</li><li>Practice instrumenting application code using the OpenTelemetry SDK to generate telemetry data.</li><li>Configure the OpenTelemetry Collector to handle data processing, batching, and exporting to backends.</li><li>Apply semantic conventions to ensure consistent and meaningful performance data across services.</li><li>Analyze distributed traces and visualize service performance using Jaeger and Grafana dashboards.</li></ul>The course begins by defining core observability concepts and the OTEL specification, then guides you through practical instrumentation techniques. We conclude by setting up data collectors and connecting them to popular visualization and analysis tools. This course is designed for beginner developers, DevOps engineers, and architects who need to implement or manage observability in microservice environments. No prior experience with OpenTelemetry is required. Start building better visibility into your systems today.
