Distributed tracing using Jaeger with Cassandra for Kubernetes

Submitted May 5, 2020

With emergence of microservices, distributed tracing is increasingly more important. To debug an issue, one needs to find which services it passed through - and which service had an issues. Jaeger is an open source distributed tracing project which helps achieve this.

In this talk I will explain how to setup Jaeger with Cassandra on Kubernetes cluster.

Target Audience - DevOps / SRE folks in companies trying to implement distributed tracing

Key takeways -
1. Overview of distributed tracing, existing choices - their pros & cons
2. How to setup Jaeger in Kubernetes infra
3. Setting up backend storage system (Cassandra) to store Jaeger metrics, trade off between different storage systems
4. Live example with sample application


  • What is distributed tracing?
  • How does tracing differ from logs?
  • Tools and cost to run distributed tracing in-house
  • Jaeger Architecture
  • Steps to setup Jaeger in Kubernetes
  • Cassandra setup for storing Jaeger traces
  • Sample application
  • How to read flamegraphs & debug application issues using it
  • Monitor Jaeger using Prometheus and Grafana
