OpenTelemetry: Observability with JavaScript
Production systems fail silently without proper observability—and most JavaScript teams lack visibility into what’s actually happening in their apps. This course teaches you OpenTelemetry, the industry standard for collecting traces, metrics, and logs, so you can diagnose issues before they hit users. In under an hour, you’ll move from observability blind spot to actionable insights.
AIU.ac Verdict: Ideal for JavaScript developers and DevOps engineers who need production-grade observability without the vendor lock-in. You’ll gain hands-on skills with OpenTelemetry’s core APIs and instrumentation. Note: assumes solid JavaScript fundamentals; doesn’t cover distributed systems architecture in depth.
What This Course Covers
You’ll start with observability fundamentals—why tracing, metrics, and logs matter separately and together—then move into OpenTelemetry’s architecture and JavaScript SDK. The course covers manual instrumentation of Node.js and browser applications, automatic instrumentation via agents, and exporting telemetry to backends like Jaeger and Prometheus. You’ll work through real scenarios: instrumenting API endpoints, tracking async operations, and correlating logs with traces.
The practical focus means you’ll configure exporters, set up sampling strategies, and integrate OpenTelemetry into existing Express or Next.js applications. By the end, you’ll understand how to instrument your own services, choose the right instrumentation approach for your stack, and troubleshoot production issues using collected telemetry data.
Who Is This Course For?
Ideal for:
- Backend JavaScript developers: Building Node.js APIs and services who need production observability without vendor-specific tools.
- Full-stack engineers: Responsible for both client and server observability in JavaScript applications.
- DevOps and platform engineers: Setting up observability infrastructure for JavaScript-heavy organisations.
May not suit:
- JavaScript beginners: Requires confident async/await, event loops, and module knowledge.
- Frontend-only developers: Focuses on backend instrumentation; browser observability covered briefly.
Frequently Asked Questions
How long does OpenTelemetry: Observability with JavaScript take?
49 minutes. Designed for busy engineers who need practical skills without lengthy commitments.
Do I need to know OpenTelemetry before starting?
No. The course assumes JavaScript competence but teaches OpenTelemetry from first principles.
Will this work with my existing monitoring tools?
Yes. OpenTelemetry is vendor-agnostic and exports to Datadog, New Relic, Jaeger, Prometheus, and others.
Is this course hands-on?
Yes. Pluralsight’s sandbox labs let you instrument real applications during the course.
