A network management system (NMS) is a combination of hardware and software used to monitor and administer a computer network.
An NMS manages the network elements, also called managed devices. Device management includes faults, configuration, accounting, performance, and security (FCAPS) management. Management tasks include discovering network inventory, monitoring device health and status, providing alerts to conditions that impact system performance, and identification of problems, their source(s) and possible solutions.
