What is observability? The ultimate guide for IT teams

This article explains observability in IT as the ability to understand a system's internal state by analyzing the relationship between its inputs and outputs, going beyond simply monitoring for known issues. It emphasizes that observability actively gathers relevant data – logs, metrics, traces, events, and profiles – to understand why something is happening, not just what is happening, enabling proactive troubleshooting and improved system reliability. While related to monitoring, observability focuses on application workflows and deeper analysis to gain a holistic understanding of system behavior and align with business objectives.
