Network Management System

A network management system is in charge of carrying out assistance services for network monitoring and networking administration groups The network management system uses a combination of various hardware and software to ensure efficient monitoring and administration of networks In addition , it is the objective of a network management system to inform and support network managers in sustaining network efficacy Constant monitoring of network topology (such as system failures or crashed servers and network connections ) and traffic (such as slow traffic or overloaded servers ) is the responsibility of

network monitoring groups . Network administrators , on the other hand , are in charge of the maintaining the technical aspect of networks : such as communications (designation and implementation of data communications knowledge in troubleshooting and technology etc , networking (knowledge in operating systems , hardware and software , identification and resolution of network problems , etc , administration (network service coordination , detection and prevention of network intrusion , etc , and development (network communication strategy planning , technical support training , etc . Network management system , network monitors and network administrators work hand-in-hand to ensure that alarms , events , and alerts are brought to the network manager . The network manager , in turn assures that these alarms , events , and alerts are properly and immediately addressed

Network management systems use several event categories and event-based transactions inform network managers of alarms , events , and alerts Event categories group events in a single group to easily identify problems in a network system . Numerous event categories are available to network management systems . These may be cluster events , environmental events , memory events , network events , operating system events , power events , processor events , security events , software events , and storage events . Cluster events are primarily concerned with the detection of cluster or node failures . Environmental events are events related to system environments such as voltage antenna , current , and temperature Memory events focus on the system memory , whether there are alterations in memory capacity and ECC or error-correcting code errors . Network events works on the network interface card status , such as crashed links and failure in adapters . Operating system events monitor system crashes Power events are concerned with temperature , current , voltage , and battery supply . Processor events indicate failure in processors alteration in processor type of number , and errors in configuration Security events monitor nodes , detects system hardware breaches , and changes in security setting . Software events are related to the status of the system (either system up or system down . Finally , storage events are concerned with disks , controllers , drives , UPS , batter backup units and such . These event categories are responsible for tracking and creating logs , registry or reports of alarms , events , or alerts that occurs in their specific areas

Aside from these event categories , there are also certain protocols and specific software configurations that are used in notifying alerts events , and alarms . For instance , network management platforms have network maps available for network management system personnel . Graphic network maps are capable of displaying status of network elements specifically routers and switchers . Fault management should also be employed in network management systems . This would...
