Introduction

This repo shows how to use OpenTelemetry with multiple NestJS apps. I will later how some of the hurdles in other explanations were overcome.

Guidance from https://www.tomray.dev/nestjs-open-telemetry was used but modified

Running

Run everything via docker-compose

• Run Jaeger backend and the three nestjs apps with docker compose up --build
• Access Jaeger UI at http://localhost:16686
• Make a call to nest1 app with curl --location 'http://localhost:3001/deepcalls'

Jaeger UI can be accessed at http://localhost:16686.
