IBM Tivoli NetView Essay
IBM Tivoli NetView
The IBM Tivoli NetView is a network management system from IBM is part of the IBM Open-Network Architecture (ONA) and provides the five functional requirements of any network management system as specified by the Open System Interconnection (OSI) model, viz - IBM Tivoli NetView Essay introduction. Fault Management, Configuration Management, Performance Management, Security Management and Accounting Management. IBM Tivoli NetView is a scalable, comprehensive, distributed network solution. Tivoli NetView discovers TCP/IP networks, displays network topologies, correlates and manages events and SNMP traps, monitors network health, and gathers performance data. Tivoli NetView meets the needs of managers of large networks by providing the scalability and flexibility to manage mission-critical environments (IBM, 2007).

The salient features of IBM Tivoli NetView are:
It provides a scalable distributed management solution
It quickly identifies the root cause of network failures
It builds collections for management of critical business systems
It integrates with leading vendors, such as CiscoWorks2000
It maintains device inventory for asset management
It measures availability and provides fault isolation for problem control and management
It reports on network trends and analysis
Tivoli NetView can be used to discover TCP/IP networks, display network topologies co-relate and manage events and Simple Network Management Protocol (SNMP) traps, monitor network health and gather network performance data. A root-cause analysis feature built into Tivoli NetView is Router Fault Isolation. This feature enables immediate concentration on the failing device in the event of a serious network problem. The affected network regions can be then marked as unreachable. It quickly identifies and focuses on the root cause of a network error, reducing the time required to respond to and resolve a network error to a great extent. This also reduces event traffic. It is possible to manage more than one network on a single server by using Tivoli NetView as it controls access to and views of the network
Switch port statuses can be continuously scanned by Multiprotocol Label Switching (MPLS) and other switch diagnostic tools incorporated in Tivoli NetView. This enables quick identification of any network error that may be because of ports being inadvertently blocked.
Management based on policies
Network resources that require similar management can be grouped using Tivoli NetView SmartSets and common policies and be applied to these distinct sets. As a result a group of resources can be managed as it they constituted a single device. Network resources can be grouped type, location, vendor, services offered or other characteristics.
Distributed Management Environment
Tivoli NetView can be used to set up a distributed management environment. The IBM Tivoli NetView Mid-Level Manager can be used to distribute management functions to remote locations that cannot support full-scale management. The Mid-Level Manager can perform status polling, threshold setting, event automation and automatic detection of new or deleted devices. The Tivoli NetView browser interface provides remote access to network information. Users in remote locations can view network information from any supported browser and perform network diagnostics such as ping, traceroute demand poll, non-graphical generated management information base (MIB) applications and MIB browser. Tivoli NetView can also be configured to operate in a regional mode. This enables most problems to be handled at the local management level only leaving the network operations centre free to monitor critical systems.
Extending the Scope
Tivoli NetView integrates with CiscoWorks2000 to enable configuration and efficient management of Cisco devises in a network. Tivoli NetView supports MPLS, Hot Standby Router Protocol by Cisco and unnumbered serial interfaces to help manage and represent complex topologies and provide accurate status information. Moreover, any of the network devices such as hubs, routers, bridges, switches, workstations, PCs, laptops and printers can be included or excluded from the purview of the network management system by specifying the nodes, device types or address ranges.
Automated Response to Events
The rules-based event correlation engine of Tivoli NetView graphically constructs guidelines to implement business policies. It can help diagnose root problems without reporting all symptomatic events. Tivoli NetView has the capability to manage events locally or centrally by propagating them to other Tivoli applications such as Tivoli Enterprise Console for advanced event correlation. It can handle diverse actions when responding to events and cases of exceeded thresholds including paging, email and programmable responses to specific failures.
Tivoli NetView can be integrated with other IBM network management products such as Tivoli Enterprise and Tivoli Decision Support Network Guides to extend its capabilities.
Tivoli Enterprise Console enables consolidation and correlation with enterprise events, including network events. Tivoli Inventory can be coupled with Tivoli NetView to add network device information to the Tivoli Inventory Database.
Similarly, Network Element Status enables a detailed view of the health status and behavior of individual network elements such as routers, servers, end systems, etc. The Network Event Analysis helps to provide a holistic view of network and Tivoli NetView event flow and event traffic. Network Segment Performance can be used to provide a view of the behavior of a network segment .
