How does a network monitoring tool operate?

A network infrastructure’s individual equipment, such as routers, switches, servers, etc., are examined by a network monitoring tool. The network monitoring software is connected to each and every device in the network infrastructure. The network monitoring tool then offers network administrators information on the condition and functionality of network components. If there is a issue with the network, it notifies the network administrator so that it can be rectified right away and the performance and health of the network are maintained.
