Network monitoring is the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator (via email, SMS or other alarms) in case of outages or other trouble. Network monitoring is part of network management.Network Monitor is a deprecated packet analyser. It enables capturing, viewing, and analysing network data and deciphering network protocols. It can be used to troubleshoot network problems and applications on the network.
While an intrusion detection system monitors a network for threats from the outside, a network monitoring system monitors the network for problems caused by overloaded or crashed servers, network connections or other devices.
