Modern cloud-native applications run across countless services, regions, and runtimes, and generate mountains of telemetry that often feel more confusing than helpful, making it difficult to find the root cause when things go wrong.
This book shows you how to bring order and clarity to observability with OpenTelemetry. It explains its core components, practical setup steps, and the real-world impact of adopting an open observability standard.
Whether you’re just exploring observability or ready to standardize across your organization, this book will demonstrate how to do it with confidence.
What you’ll learn
What observability means, how it differs from traditional monitoring, and why it’s critical for today's complex systems
How to interpret and seamlessly correlate the core observability signals: logs, metrics, traces
The role of the OpenTelemetry SDKs, Collector, and protocol in creating consistent telemetry pipelines
Best practices for applying consistent, meaningful context to every signal using resource attributes
Practical, step-by-step instructions for instrumenting real-world applications using automatic and manual techniques
How to distinguish a truly OpenTelemetry-native platform from one that merely "supports" OpenTelemetry and why it matters
Strategies for managing telemetry quality at scale, to ensure your data is actionable and cost-effective`
