Passive Monitoring
Passive monitoring is an approach to system and network observation that collects data without actively probing or interfering with the monitored environment. It involves analyzing traffic, logs, and metrics generated by normal operations, such as network packets, application logs, or infrastructure telemetry. This method provides insights into performance, security, and health while minimizing impact on the system.
Developers should use passive monitoring for real-time observability in production environments where active probing could disrupt services or introduce overhead. It is essential for detecting anomalies, troubleshooting issues, and ensuring compliance without affecting user experience, commonly applied in cybersecurity, application performance monitoring (APM), and network management.
