Introduction

In the fast-paced world of DevOps, delivering high-performing, reliable applications requires more than just monitoring — it demands observability. Observability goes beyond tracking metrics; it’s about gaining deep insights into system behavior to detect, debug, and prevent issues before they impact users.

In this blog, we’ll explore:

• Why observability matters in DevOps.
• The key tools that drive observability.
• Best practices to implement observability effectively.
• Code examples to demonstrate its practical implementation.

What is Observability in DevOps?

Observability is the ability to infer the internal state of a system based on its outputs, such as logs, metrics, and traces. It’s a key principle in modern DevOps that enables teams to:

1. Quickly identify performance bottlenecks.
2. Debug and resolve incidents faster.
3. Optimize application…
