Network management tools are software or hardware used to monitor, control, and improve network performance and security. These tools help network administrators detect and fix problems, manage devices and connections, and ensure service continuity. The following are the most common types and examples of tools used:

---

1. Monitoring and analysis tools

• Function: Monitor network performance and identify bottlenecks or faults.
• Examples:
  • Nagios: An open source tool for monitoring servers and networks.
  • SolarWinds Network Performance Monitor: A comprehensive performance monitoring and analysis tool.
  • Zabbix: An open source platform for monitoring networks and infrastructure.

---

2. Device management tools

• Function: Manage settings of network devices (such as routers and switches).
• Examples:
  • Cisco Prime Infrastructure: Integrated device management from Cisco.
  • WhatsUp Gold: Comprehensive device management and monitoring.
  • ManageEngine OpManager: A tool for monitoring and managing network infrastructure.
