Understanding Observability: Metrics, Traces, and Logs

Modern applications are distributed and complex. Observability helps teams understand system behavior by analyzing metrics, traces, and logs.

The Three Pillars

• Metrics: Numerical system indicators like CPU or latency
• Traces: End-to-end request tracking across services
• Logs: Detailed event data for debugging

Why Observability Matters

With the rise of microservices, observability is essential for detecting bottlenecks, optimizing performance, and preventing outages.
