An Efficient Network Monitoring and Management System

Large organizations always require fast and efficient network monitoring system which reports to the network administrator as soon as a network problem arises. This paper presents an effective and automatic network monitoring system that continuously monitor all the network switches and inform the administrator by email or sms when any of the network switch goes down. This system also point out problem location in the network topology and its effect on the rest of the network. Such network monitoring system uses smart interaction of Request Tracker (RT) and Nagios softwares in linux environment. The network topology is built in Nagios which continuously monitor all of the network nodes based on the services defined for them. Nagios generates a notification as soon as a network node goes down and sends it to the RT software. This notification will generate a ticket in RT database with problematic node information and its effect on the rest of the network. The RT software is configured to send the ticket by email and sms to the network administrator as soon as it is created. If the administrator is busy at the moment and does not resolve the ticket within an hour, the same ticket is automatically sent to the second network responsible person depending upon the priority defined. Thus, all persons in the priority list are informed one by one until the ticket is resolved.
