Mastering Distributed Tracing

Summary

This chapter introduced a demo application, HotROD, that is instrumented for distributed tracing, and by tracing that application with Jaeger, an open source distributed tracing system, demonstrated the following features common to most end-to-end tracing systems:

• Distributed transaction monitoring: Jaeger records the execution of individual requests across the whole stack of microservices, and presents them as traces.
• Performance and latency optimization: Traces provide very simple visual guides to performance issues in the application. The practitioners of distributed tracing often say that fixing the performance issue is the easy part, but finding it is the hard part.
• Root cause analysis: The highly contextualized nature of the information ...
