Practical OpenTelemetry for Distributed Systems

When a request moves through multiple services, databases, message brokers, and containers, finding out where something went wrong can quickly become frustrating. Logs show only part of the story. Metrics reveal that a problem exists, but not always why. Traces help, but only when instrumentation, context propagation, and telemetry pipelines are configured correctly.

Practical OpenTelemetry for Distributed Systems gives you a clear, step-by-step path from OpenTelemetry fundamentals to production-ready observability.

You do not need previous OpenTelemetry experience. The book introduces each concept progressively through one continuous distributed application, OrderFlow, so you can see how traces, metrics, logs, OTLP, automatic instrumentation, context propagation, Collector pipelines, sampling, Kubernetes, security, and reliability work together in a real system.

Key Features

• Hands-on, step-by-step learning with one continuous project
• Automatic and manual instrumentation
• OpenTelemetry Collector pipelines
• Traces, metrics, logs, and multi-signal correlation
• Sampling, cardinality, telemetry volume, and cost control
• Kubernetes and cloud-native observability
• Security, reliability, and production architecture
• Practical troubleshooting, exercises, and readiness checklists

Mistakes are part of the learning process. You will deliberately break propagation, investigate missing telemetry, simulate slow dependencies, test Collector failures, and verify each fix. Every working trace, useful metric, correlated log, and repaired pipeline builds practical confidence.

What You Will Learn

You will learn how to:

• Instrument distributed services
• Follow trace context across HTTP and messaging
• Design useful metrics and structured logs
• Configure Collector receivers, processors, and exporters
• Apply head and tail sampling
• Diagnose latency, retries, database issues, and broken telemetry
• Deploy and scale OpenTelemetry in Kubernetes
• Secure telemetry infrastructure
• Design a vendor-neutral production observability architecture
