Summary  
This chapter covers implementing code to collect, analyze, and monitor performance metrics—such as bandwidth usage, latency, packet loss, and uptime—and to automate threshold-based alerts for proactive issue resolution.

General domain of usage  
Network administration

Monitoring network performance is essential for ensuring a smooth and efficient network. It involves tracking key metrics such as bandwidth usage, latency, packet loss, and uptime to maintain optimal functionality. This proactive approach allows network administrators to anticipate and resolve issues before they disrupt users.

Effective network monitoring should encompass these metrics. Tools like SolarWinds, PRTG, and Zabbix allow administrators to customize dashboards displaying network health, set performance thresholds, and automate alerts for potential issues. These advanced monitoring tools provide insights into traffic patterns, enabling administrators to optimize resource allocation and address bottlenecks.
