OpenTelemetry: Observability with JavaScript
Get complete visibility into your JavaScript applications using OpenTelemetry. This course will teach you how to instrument frontend and backend code to monitor and debug distributed systems.
What you'll learn
Debugging and monitoring modern JavaScript apps is challenging due to their distributed nature. In this course, OpenTelemetry: Observability with JavaScript, you’ll learn to add telemetry to web and Node.js services for complete end-to-end observability. First, you’ll explore how OpenTelemetry works and how to instrument Node.js and browser code using auto and manual techniques. Next, you’ll discover how to capture and export traces and metrics to the cloud, including AWS CloudWatch, and use them to analyze performance bottlenecks. Finally, you’ll learn how to apply these insights to improve reliability and user experience in production systems. When you're finished with this course, you'll have the skills and knowledge of OpenTelemetry needed to instrument your JavaScript apps and use that data to make informed engineering decisions.
