  1. Network Management PresentationHP Openview Christopher Scott December 10, 2004

  2. OpenView Network Node Manager (NNM)

  3. OpenViewNetwork Node Manager • Overview • How it works • Capabilities • Technical and business benefits • Summary

  4. Network Node Manager Overview • 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

  5. What does it do? • Dynamically maps out your network • Collects critical information about you network • Correlates the information it collect • Maintains a relational database • Provides report generation

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

  7. SNMP Network Mgmt Model • Manager • 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

  8. Manager-Agent Communication through SNMP SNMP Request with Community Name Retrieve (get) management information Manager Agent MIB SNMP Replies Alter (set) management information SNMP Traps

  9. Automatic Discovery and Layout • All IP and Level 2 devices on the network are automatically discovered and mapped • IPX devices are also discovered • Map is a logical representation of your network • Automatic discovery may take several hours or even overnight

  10. Example of network discovery and layout

  11. 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

  12. Typical Submap Hierarchy

  13. 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

  14. DIDM (cont’d) • 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

  15. Simplified Distribution Model for NNM

  16. 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

  17. Multiple Management Consoles

  18. Sample map views

  19. Sample map views

  20. Sample map views

  21. 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 multi-vendor environment

  22. 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

  23. Business Benefits • Network Management can help achieve those goals through: • Accounting Management • Obtains statistical information on network use • Track individual resource utilization • Security Management • Protects the network and its systems from unauthorized access, use, and harm

  24. Summary • hp OpenView NNM is a robust 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
