The majority of network monitoring software keeps a constant eye on a network. However, implementing monitoring tools is done to ensure the performance of computers and network services, not to resolve system problems. Network monitoring enables proactive reaction, data security, data collection and overall computer system health. Monitoring a computer system is equally as crucial as the system itself. The use of a network monitoring tool makes it easy to track the functioning of the entire network. Network monitoring tools (software or hardware) track, detect, examine and convey network performance, health and availability, as well as the data flowing through them regularly. Software applications and tools are used to conduct network monitoring. Network monitoring is the technique of regularly examining a computer network to ensure maximum performance and availability.
