There are several common network monitoring tools used to monitor and manage computer networks. Some of these tools include:
1. Ping: Ping is a basic network monitoring tool that sends a small packet of data to a specific IP address or domain name and measures the time it takes for the packet to travel to the destination and back. It helps to check the connectivity and response time of a network device.
2. Traceroute: Traceroute is a tool that traces the route taken by packets from the source to the destination. It shows the IP addresses of the routers or intermediate devices through which the packets pass, helping to identify any network bottlenecks or issues.
3. SNMP (Simple Network Management Protocol): SNMP is a protocol used for network management and monitoring. It allows network administrators to monitor and manage network devices such as routers, switches, and servers. SNMP-based monitoring tools collect and analyze data from these devices, providing insights into network performance and health.
4. Wireshark: Wireshark is a powerful network protocol analyzer that captures and analyzes network traffic in real-time. It allows network administrators to inspect packets, identify network issues, and troubleshoot problems. Wireshark supports a wide range of protocols and can be used for both wired and wireless networks.
5. Nagios: Nagios is a popular open-source network monitoring tool that provides comprehensive monitoring and alerting capabilities. It can monitor various network services, servers, and devices, and send notifications when issues are detected. Nagios can be customized and extended with plugins to suit specific network monitoring requirements.
6. PRTG Network Monitor: PRTG is a commercial network monitoring tool that offers a wide range of monitoring features. It can monitor network devices, bandwidth usage, server performance, and various other parameters. PRTG provides a user-friendly interface and customizable dashboards for easy monitoring and reporting.
7. SolarWinds Network Performance Monitor: SolarWinds NPM is a comprehensive network monitoring tool that provides real-time visibility into network performance and health. It offers features like network device monitoring, traffic analysis, and alerting. SolarWinds NPM also includes advanced features like network mapping and capacity planning.
These are just a few examples of common network monitoring tools. The choice of tool depends on the specific monitoring requirements, network size, and budget of the organization.
