Monitoring of networks with dynamic topology based on software Nagios

Network management is one of the ways to decrease costs for network operation and loss decreasing, caused by network falls. Some tasks in network management are performed by monitoring system. The present systems of monitoring of network with a dynamic topology are not suitable for networks with dynamic topology. Among free software, due to its functional characteristics Nagios can be singled out, which was designed to monitoring of static networks. However, Nagios can set network topology of different types including network with dynamic topology. Topology of networks with a dynamic topology is more changeable than in networks with static topology. Practical experience shows that Nagios is sensitive to peak demand on a hardware it is installed. In the current version of Nagios, information of network nodes must be entered manually. To avoid loss of information on network and nodes state, with topology change, it is required to determine the number of temporary selected centers and isolated networks.
