Abstract

In this thesis, we have identified techniques and approaches that are most commonly encountered in network management systems. We have described availability and performance monitoring techniques. Selection of monitoring technique depends on the complexity of monitored parameters and preliminary established architecture. Network monitoring suggests architecture in which centralized manager collects and analyses data from managed devices. Managed devices expose their network statistics through objects defined within the Management Information Base. Simple Network Management Protocol allowing the manager to communicate with the managed hosts. Afterwards we analyse network monitoring and graphing tool Cacti. Cacti allows a manager to poll managed devices and graph the gathered data. In the last part we cover the details of establishing network management system in which we monitor local and remote network resources. Cacti has emerged as adaptable tool for monitoring computer networks.
