2 What is HP Openview History OpenView Products Let s discuss Network Node Manager (NNM) NNM:How it works Benefits Summary

3 HP OpenView HP OpenView was a Hewlett Packard product range consisting of network and systems management products. In 2007, HP OpenView was rebranded under the HP Software name. HP OpenView was most commonly described as a suite of software applications which allow large-scale system and network management of an organization's IT infrastructure. It included optional modules from HP as well as third parties which connect within the well-defined framework and communicate with one another.

4 History The foundation product was Network Node Manager (NNM), providing GUI services for other products which integrated with it. NNM is generally used in its own right to manage networks (possibly in conjunction with other products) HP has a history of acquiring network management software companies. In 2004, it bought Novadigm and its Radia suite. In 2005, it acquired Peregrine Systems with its IT asset and service management software and integrated it into HP OpenView. In November 2006, HP completed its purchase of Mercury Interactive Corp., and from February 2007 is integrating Mercury application and software lifecycle management into HP Software. In August 2007, HP announced its intention to purchase Opsware. In early 2007, alongside the integration of Mercury, HP OpenView was rebranded under the HP Software name. The OpenView and Mercury brands are being phased out. HP OpenCall will continue, however, as a sub-brand of HP Software.

It collects, processes and correlates usage records and events from network elements and service applications across voice and data services for prepaid, post-paid and real-time charging in wireless, wireline and cable networks. This usage data can be passed on to business support systems for usage-based billing systems, capacity management and analysis of subscriber behavior.

9 Network Node Manager (NMM) Network Node Manager (NNM) is a Hewlett Packard OpenView product which manages networks. Network management tool Proactive network management Provides a solid solution for managing dynamic IP networks NNM is starting point for implementing a network management solution It uses SNMP to talk to network devices, allowing them to be auto discovered, monitored and controlled.

10 Network Node Manager (Cont d) NNM determines and displays physical and logical connectivity in networks, as well as information pertaining to protocols running over the network. It also allows historical data to be collected and viewed/graphed Dynamically maps out your network/ Discover the network Collects critical information about the network/ pinpoint the problems Proactive management Correlates the information it collects Maintains a relational database Provides report generation Access from anywhere

12 NNM: How does it work? NNM uses several protocols to maintain communication with each managed device SNMPv1, SNMPv2 TCP/IP, IPX UDP ICMP ARP/RARP

13 Manager SNMP Network Mgmt Model A manager is an application that executes network management operations The manager monitors and controls agent systems SNMP agent Resides on a managed node An application that acts on behalf of an object Object Anything that will be managed Host, router, hub, application, database SNMP Request with Community Name Retrieve (get) management information Manager SNMP Replies Agent MIB SNMP Traps Alter (set) management information

14 SNMP (Simple Network Management Protocol) SNMP network management is based on three parts: SNMP Protocol Defines format of messages exchanged by management systems and agents. Specifies the Get, GetNext, Set, and Trap operations Structure of Management Information (SMI) Rules specifying the format used to define objects managed on the network that the SNMP protocol accesses Management Information Base (MIB) A map of the hierarchical order of all managed objects and how they are accessed Community names are used to define where an SNMP message is destined for. Set up your agents to belong to certain communities. Set up your management applications to monitor and receive traps from certain community names.

15 Automatic Discovery and Layout All IP/devices on the network are automatically discovered and mapped Map is a logical representation of your network Automatic discovery may take several hours or even overnight IPX devices are also discovered

16 Example of network discovery and layout

17 Network Discovery (cont d) NNM discovers the following objects and put them on the default map Internet-level submap IP networks, gateways, routers and multihomed workstations Network-level submaps Bus, star and ring segments Segment-level submaps Hosts, gateways, routers, switches, hubs, and bridges Node-level submaps Network interface cards

18 Typical Submap Hierarchy

19 Distributed Internet Discovery and Monitoring (DIDM) Large networks may require this distributed model Spreads discovery, monitoring, and polling across several Network Node Managers acting as collection stations Collection stations monitor some portion of the network and inform the management station of changes NNM can serve as a management station, a collection station, or both Management stations Role is to make the network management functionality available to the users Collection stations Role is to be a collection point in the overall network management system

20 Simplified Distribution Model for NNM

21 Management Consoles NNM gives the ability to have 15 to 25 operators simultaneously monitoring the network Operators can share one map, or have individual maps Individual maps create area of responsibility on the network for each operator More efficient in large networks

32 Challenges to IT Service Management User dissatisfaction/increased user expectations Deploying network services, while maintaining productivity Keeping networks and systems operational 24/7/365 Producing faster, more predictable response times Integrating and managing complex systems in a multivendor environment

33 Technical benefits Network Management can help achieve those goals by: Fault and Problem Management Reduced downtime of network systems and devices Quick detection and correction of network problems Performance Management Ability to monitor data to anticipate problems Log information for historical analysis

34 Business Benefits Network Management can help achieve those goals through: Accounting Management Obtains statistical information on network use Track individual resource utilization Security Management

35 Summary hp OpenView NNM is a network management platform that can provide a graphical look into your network and provide many benefits like Fault and Problem management, Performance management, etc Makes network management proactive instead of reactive NNM uses SNMP to discover devices on the network and automatically manage and monitor them NNM can play an integral role in achieving both the technical and business goals of an organization
