  1. OpenView and Network Node Manager Fundamentals

  2. A Network Management Protocol – SNMP Simple Network Management Protocol Management Station Managed Node SNMP Services Status and Configuration Information SNMP Agent OpenView and NNM Fundamentals

  3. The Management Information Base root (world) 2 join-iso-ccitt 0 ccitt 1 iso 3 org 2 member body 6 dod 1 reg authority 0 std 1 internet private 2 mgmt experimental 1 directory 4 3 mib-2 1 snmp system tcp transmission egp interfaces udp icmp at ip OpenView and NNM Fundamentals

  4. The Basic Components of NNM Remote System NNM Local System NNM Processes and Applications NNM Databases NNM User Interfaces Web Launcher Web Browser OpenView and NNM Fundamentals

  5. How NNM Works Processes associated with a user’s interactive ovw session. Foreground Processes, started by ovstart, which monitor network nodes. Background Processes (Services) Network OpenView Database Contains data stored and used by foreground and background NNM processes. OpenView and NNM Fundamentals

  7. The OpenView Databases • Object database. Contains general object information, including some object attributes and capabilities. • Topology database. Contains specific topology information maintained and used by the IP network discovery and layout services. • Map database. Contains map-specific information, such as submap customizations and symbol placement. OpenView and NNM Fundamentals

  8. Basic NNM Windows OpenView and NNM Fundamentals

  9. The Submap Window Components Menu Bar Tool Bar Viewing Area Status Bar OpenView and NNM Fundamentals

  10. Introduction to Maps and Submaps Map Default Submap Submap OpenView and NNM Fundamentals

  11. The IP Submap Hierarchy Root Internet Network Network Segment Segment Segment Segment Node Node Node Node Node Node Node Node OpenView and NNM Fundamentals

  12. Introduction to Objects and Symbols Real World Object Symbol Object Database OpenView and NNM Fundamentals

  13. Accessing Object Descriptions OpenView and NNM Fundamentals

  14. Capabilities and General Attributes • Describe the object. • Set by NNM during discovery. • Capabilities cannot be changed. • General attributes are rarely changed. OpenView and NNM Fundamentals

  15. IP Map Object Attributes • IP-specific attributes • Set and maintained by IP Map • Vary with the object type OpenView and NNM Fundamentals

  16. Locating an Object • An object (corresponding symbols) may be located in the map via one of the following search methods: • By Selection Name • By Attribute • By Comment • By Symbol Status • By Symbol Type • By Symbol Label OpenView and NNM Fundamentals

  17. Symbol Class and Subclass • Symbol class • Groups related symbols • Defines a symbol’s geometric shape • Symbol subclass • Corresponds to a symbol icon • Image displayed on a submap • Superimposed on class shape OpenView and NNM Fundamentals

  18. Status Examples IP Internet submap Network B submap Symbol Status is Normal A B 42 Compound Status is Warning B 42 Interface to B Interface to A Interface to B OpenView and NNM Fundamentals
