Abstract(s)
Network monitoring is a crucial IT process, which consists of monitoring network devices such as routers, switches, firewalls and servers for performance and fault issues. A good functioning network if vital for an organization, but unfortunately, network outages and performance issues are a part of every organization’s network. Faults, being hardware or human originated, may appear at any time and can give rise to sometimes critical situations. For this reason, network devices should be monitored continuously in a proactive way to prevent these network failures and downtimes. Identifying traffic bottlenecks, faulty components, low performance and other types of issues in an early stage minimizes or even eliminates bigger problems that can occur later on. Efficient proactive monitoring can help prevent network outage and should be implemented by every network administrator. Adopting a secure, low bandwidth consumption and compatible protocol is a good practice when implementing a monitoring solution. One such protocol is the Simple Network Management Protocol (SNMP) and provides a message format for communication between the SNMP managers and agents; it is also supported by most of the present day network devices and servers. The main goal of research described in this dissertation is the study of the various existing freeware SNMP monitoring platforms in the market today and the implementation of the one best suited for the university’s network. The solution would have to be compatible with the university’s multivendor device network and be scalable enough to permit future growth. It should also have a good alerting system to provide a pro-active approach to resolving issues. Implementation, evaluation and conclusions of the best suited monitoring solution are presented during the course of this study.
