Tracing provides insight into the performance and health of a deployed application, tracking each function or microservice that handles a given request. Tracing makes it easy to understand the end-to-end flow of a request, regardless of whether you are using a monolithic or distributed system.
Jaeger is an open source, end-to-end distributed tracing system used for monitoring and troubleshooting microservices-based distributed systems. To learn more about installing Jaeger, read the official Getting Started documentation.
