Traffic Monitoring
Traffic monitoring is the practice of collecting, analyzing, and visualizing network traffic data to understand performance, detect anomalies, and ensure security. It involves using specialized tools to capture packets, measure bandwidth usage, and track application behavior across networks. This enables organizations to optimize infrastructure, troubleshoot issues, and maintain service reliability.
Developers should learn traffic monitoring when building or maintaining distributed systems, microservices, or cloud applications to diagnose latency, identify bottlenecks, and ensure compliance with SLAs. It's crucial for DevOps and SRE roles to monitor traffic for security threats like DDoS attacks or data exfiltration, and to debug complex interactions between services in production environments.
