Reactive Monitoring
Reactive monitoring is a software monitoring approach that focuses on responding to events or issues as they occur, typically through alerts, notifications, or automated actions triggered by predefined thresholds or anomalies. It contrasts with proactive monitoring by emphasizing immediate response to problems rather than predicting or preventing them. This methodology is commonly used in IT operations, DevOps, and system administration to maintain service availability and performance.
Developers should learn reactive monitoring when working in environments where real-time issue detection and rapid response are critical, such as production systems, cloud infrastructure, or microservices architectures. It is essential for maintaining uptime, debugging incidents, and ensuring compliance with service-level agreements (SLAs), particularly in scenarios where immediate human or automated intervention is required to resolve outages or performance degradation.
