What tools do you use for network monitoring and troubleshooting?

As a network administrator, I use a variety of tools for network monitoring and troubleshooting to ensure the smooth functioning of the network infrastructure. Some of the essential tools that I rely on include:

• Wireshark: A powerful network protocol analyzer for troubleshooting network issues and analyzing traffic.
• Nagios: A robust monitoring tool for keeping an eye on network infrastructure and alerting in case of any issues.
• SolarWinds Network Performance Monitor: Provides real-time visibility into network performance and can identify and resolve network issues quickly.
• NetFlow Analyzer: Helps in monitoring and analyzing network traffic flow for efficient troubleshooting.
• PRTG Network Monitor: A comprehensive tool for monitoring network performance, availability, and bandwidth usage.

By utilizing these tools effectively, I can proactively monitor the network, identify potential issues, and troubleshoot them promptly to ensure minimal downtime and optimal network performance.
