Jaeger

Introduction

Jaeger is an open-source, end-to-end distributed tracing system originally developed at Uber and now a CNCF graduated project. It implements the OpenTracing and OpenTelemetry specifications, supporting context propagation, root cause analysis, performance optimization, and service dependency analysis for microservice architectures.
