Mastering Distributed Tracing

By: Yuri Shkuro

Overview of this book

Mastering Distributed Tracing will equip you to operate and enhance your own tracing infrastructure. Through practical exercises and code examples, you will learn how end-to-end tracing can be used as a powerful application performance management and comprehension tool. The rise of Internet-scale companies, like Google and Amazon, ushered in a new era of distributed systems operating on thousands of nodes across multiple data centers. Microservices increased that complexity, often exponentially. It is harder to debug these systems, track down failures, detect bottlenecks, or even simply understand what is going on. Distributed tracing focuses on solving these problems for complex distributed systems. Today, tracing standards have developed and we have much faster systems, making instrumentation less intrusive and data more valuable. Yuri Shkuro, the creator of Jaeger, a popular open-source distributed tracing system, delivers end-to-end coverage of the field in Mastering Distributed Tracing. Review the history and theoretical foundations of tracing; solve the data gathering problem through code instrumentation, with open standards like OpenTracing, W3C Trace Context, and OpenCensus; and discuss the benefits and applications of a distributed tracing infrastructure for understanding, and profiling, complex systems.

Prerequisites


In order to run the Tracing Talk chat application, we need to deploy a number of infrastructure dependencies:

  • Apache Kafka, as the messaging platform

  • Redis, as the backend store for the chat messages

  • Apache Zookeeper, used by Kafka

  • Jaeger tracing backend to collect and analyze the traces

This section provides instructions on setting up the environment to run the chat application.

Project source code

The examples can be found in the Chapter05 directory of the book's source code repository on GitHub. Please refer to Chapter 4, Instrumentation Basics with OpenTracing, for instructions on how to download it, then switch to the Chapter05 directory to run the examples.

The source code of the application is organized in the following structure:
