Into to distributed tracing

Distributed tracing, also called distributed request tracing, is a method used to profile and monitor applications, especially those built using a microservices architecture. Distributed tracing helps pinpoint where failures occur and what causes poor performance. We have used opentelemetry standards and Jaeger UI in this setup.

Run the app

There is a docker-compose.yaml in this directory. Change your terminal to this folder and run:

docker-compose build

docker-compose up

You can access the app on http://localhost.
You should now see the complete architecture in the browser
