Monitoring

Monitoring is the process of observing, tracking, and analyzing the performance, health, and behavior of applications or infrastructure over time. It involves collecting metrics, logs, and traces to detect issues, optimize performance, and ensure reliability.

Monitoring is a proactive practice: it helps teams identify and resolve problems before they impact users or business operations.
