Debugging Microservices Architectures
Apply tracing and logging techniques specifically to diagnose and resolve issues within complex microservices environments.
Debugging Microservices: The Challenge
Welcome to debugging microservices! Unlike a single, large application, microservices break down your system into many small, independent services.
This distributed nature brings amazing benefits, but also unique debugging challenges. A single user request might touch dozens of services, making it hard to follow its journey.
The Pillars of Observability
To effectively debug microservices, we rely heavily on observability. This means understanding the internal state of your system from external outputs.
- Logs: Detailed records of events within each service.
- Metrics: Numerical data (CPU usage, request count) to track service health.
- Traces: Visual paths of requests as they flow through multiple services.
We'll focus on logs and traces today.
