Network Monitoring Technologies

Imagine walking into a sprawling, automated factory operating entirely in pitch darkness. You can hear the hum of engines and feel the vibration of conveyor belts, but without instrumentation, you cannot tell if a machine is running optimally or tearing itself apart. A computer network is precisely this invisible factory. Without deliberately configured monitoring and logging systems, network administrators are essentially blind, reacting to catastrophic failures only after the users begin to complain. To manage, secure, and troubleshoot modern enterprise networks, we must build a comprehensive nervous system that collects operational telemetry, inspects traffic, and correlates seemingly disparate events into a coherent picture of network health.
