Distributed Tracing with OTel Collector, and Jaeger

1. Overview

Distributed tracing is essential for understanding the flow of requests across microservices in a complex system. In this guide, we'll set up a tracing pipeline using eBPF, the OpenTelemetry Collector (OTel Collector), and Jaeger.

3. Components

• PingAckAPI:
  • Is a light weight net/http API
  • Exposes /ping and /delay
  • Also has Swagger integrated for easy
• OpenTelemetry Collector:
  • Collects, processes, and exports telemetry data (including traces).
  • Acts as an intermediary between eBPF and Jaeger.
• Jaeger:
  • Distributed tracing system for visualizing and analyzing trace data.

3. Running code

Pre-requisites.

1. Docker

Steps to run code

1. cd tracing-with-open-telemetry
2. ./run.sh
3. To make test api calls http://localhost:7997/swagger/index.html
4. To access Jaeger http://localhost:16686/

This is how your final selections on Jaeger should look like
