- Learn the three pillars of observability: Distributed Traces, Metrics, and Logs
- Use the OpenTelemetry Java Agent for zero-code instrumentation to get instant visibility
- Explore context propagation and baggage to trace requests across distributed systems
- Configure and deploy the OpenTelemetry Collector Pipeline to process, filter, and export telemetry data via OTLP
- Manually inject custom spans and attributes into Java code to capture critical business context
- Set up a complete observability stack using Grafana, Prometheus, Tempo, and Loki with Docker Compose
- Correlate structured Java Spring logs with OpenTelemetry traces for faster issue diagnosis
- Implement advanced head and tail sampling strategies to reduce costs without losing critical error traces
- Analyze telemetry signals to find root causes, improve performance, and reduce MTTR
- Build reusable observability modules for on-demand debugging and production-grade visibility

Requirements
- Java
- Spring Boot
- Docker / Docker Compose

Description
This intensive course is designed for experiencedJava Spring Boot Developersready to transition into aStaff or Principal Engineerrole.

You will masterOpenTelemetry (OTel), the universal cloud-native standard for instrumentation, and gain the architectural expertise to implement world-class observability in complex distributed systems.

Move beyond basic monitoring. Learn to collect, correlate, analyze, and visualize thethree pillars of modern observability: Distributed Traces, Metrics, and Logsto debug production issues faster, preempt system failures, and build highly reliable, scalable applications.

What You Will Maser:

Observability Fundamentals:Go beyond traditional monitoring by understanding theThree Pillars: Distributed Traces, Metrics, and Logsand their role in diagnosing unknown system issues.

Zero-Code Instrumentation:Instantly gain full-stack visibility by deploying theOpenTelemetry Java Agentfor seamless auto-instrumentation on your Spring Boot microservices.

End-to-End Trace Context:MasterW3C Trace Context PropagationandBaggageto accurately link requests and business context across all services in your distributed architecture.

Custom Business Spans:Manually injectcustom Spans and Attributesinto your Java code to capture rich, domain-specific data points critical for root cause analysis.

The OTel Collector Pipeline:Configure and deploy theOpenTelemetry Collectorto receive, process, filter, and export all telemetry data using the high-performanceOTLP(OpenTelemetry Protocol).

Full Observability Stack:Deploy a complete, open-source backend usingGrafana, Prometheus, Tempo, and Lokiwith Docker Compose to store, query, and visualize all collected OTel data.

Log-Trace Correlation:Integrate structured Java/Spring logs with OpenTelemetry to instantly connect raw log messages to their full transaction history.

Cost-Effective Sampling:Implement smartHead- and Tail-Based Samplingstrategies to control observability data volume and storage costs without sacrificing critical error traces.

Analyze & Reduce MTTR:Utilize aggregated telemetry signals (Traces, Metrics, Logs) to quickly find root causes, pinpoint performance bottlenecks, and drastically reduceMean Time to Resolution (MTTR).

On Demand Debugging:Build reusable, production-grade observability components to enable on-demand debugging and bring observability earlier into the development workflow.

By the end of this course, you will be able to instrument your Spring Boot applications with OpenTelemetry, gain deep visibility into distributed systems, debug issues with clarity, and strengthen your career as an advanced engineer.

Who this course is for:
- Senior developers preparing to grow into Staff Engineer, Principal Engineer, or Architect roles
- Java and Spring Boot developers who want to learn and implement observability with OpenTelemetry
