Jaeger UI is the official, React-based web interface for Jaeger, a popular open-source distributed tracing platform. It serves as a visual dashboard for developers and engineers to monitor, analyze, and troubleshoot microservices and complex software architectures.Key Features of Jaeger UITrace Visualization: It allows you to see the entire lifecycle of a single user request as it travels across various microservices, databases, and internal function calls.Timeline and Flame Graph Views: Traces are displayed in easy-to-read timelines or flame graphs, breaking down exactly how much time each service spends processing a request.Root Cause Analysis: It helps pinpoint the exact service where a delay occurs or an error is thrown.Service Dependency Graph: It automatically generates a visual map illustrating how different microservices communicate and depend on each other.Trace Filtering: You can search for traces using exact criteria such as operation name, time elapsed (latency), tags, or log errors.How it Works Under the HoodYour application microservices are instrumented with tracing libraries (like OpenTelemetry).As a request travels through your system, the execution path is collected and stored.The Jaeger Query service reads this stored trace data and powers the UI, turning the backend JSON data into interactive charts.For a visual walkthrough of how to use Jaeger UI to trace errors and debug latency in a real-world application:
