Monitoring vs. Observability: An Overview

Before we get to the main discussion, here’s an overview of some key points to keep in mind.

Monitoring is like having a security camera or a trusty watchdog for your systems. It watches predefined metrics and alerts you when something looks off.

Observability, on the other hand, is like having X-ray vision. It lets you look into your system’s inner workings to understand why things are happening, not just what’s happening.

Key differences to remember:

Monitoring tells you when something’s wrong.
Observability helps you figure out why it’s wrong.
Monitoring is reactive; Observability is proactive.
Monitoring focuses on known issues; Observability helps uncover unknown issues.

Both Monitoring and Observability are essential for keeping your systems healthy and your customers happy.
