HP Open View NNM I

1. HP Open View NNM I Eng. Nouran Nawar

2. Day 1 • SNMP Interaction • HP Products • HPOVNNM Installation • OUR LAB • Basic Component on NNM • Home Base • OVW • Home Base Vs. OVW

3. Introduction • Need to make control from single point. • OSI specific management functional Areas: • Fault Management. • Configuration Management. • Accounting Management. • Performance management. • Security management.

4. Interaction with SNMP • MS : Management Station. • MA : Management Agent. • MN : Management Node.

5. Polling • SNMP use a simplest command between Manager and Agent, using UDP/IP. “connection less” • Most of communication start by a manager. • Agent communication is response for manager. • SNMP Traps: Agent start communication when predetermined even occur.

6. SNMP Agent communication protocol • MIB : Management Information Base. • SNMP agent listen to port 161 UDP. • SNMP Manager listen to port 162 UDP “Traps”. SNMP MANAGER SNMP Get AGENT MIB Response SNMP Set Response Traps MN MS

7. Protocols Msgs of SNMP • GET • GET_Next • Get_Bulk (v2) • Inform (v2) • Set • Response • Traps Msgs sent by MS to MN Msgs sent by MN to MS

8. SNMP Versions • SNMP v1 • GET, Get Next, Set, Trap • SNMP V2 • Get Bulk, Inform, SNMP V1 • SNMP V3 • Proxy Agent, Authentication , SNMP V1, SNMP V2 • SNMP V2c

9. MIB • Access to device configuration • Standard Method to set or get data fro MN • MIB: piece of status or configuration • MIB object • NAME + Access + Type + Descr. • Access : read + write • MIB Tree

10. MIB tree Management Sub Tree

11. MIB Example • Symbolic .iso.org.dod.internet.mgm.mib-2.system.sys.sysDescr.0 = • Numeric .1.3.6.1.2.1.1.1.0 • Fully Qualified MIB object name = object ID dot notation(.) Instance ID

12. SNMP community Name • Community name to provide a level of security for SNMP. • By default: get community name is “public” • Set community name: modify configuration.

13. HP Hewlett Packard • HP open view advanced security • HP open view Dynamic Net value analyzer • HP open view Glance plus • HP open view ISP • HP open view Internet usage • HP open view Network Node manager • HP open view Performance manager • HP open view performance insight

14. What does NNM provide? • Map to your NW. • Discover layer#2 & layer#3 connectivity • Event Management and Alarm Browser • SNMP data collection, MIB graph for any variable • Data ware house, Archive NW data • Report • Web based GUI • Mange HSRP, MPLS “SPI” smart plug in

15. NNM Product structure • NNM Starter Edition “SE” • Small NW, 250 node • NNM Advanced Edition “AE” • Discover unlimited nodes, VLANs, MPLS, VPN, WAN • HP NNM-I Certificate  HP0-632

16. HP Open view prerequisites • Your machine has a static IP • NOTE: “Changing IP Make the HP Stop working” • IIS windows Component • SNMP • Java  J2re “Java 2 Runtime Environment, Standard Edition 1.4.2_06 ” min JPI 1.4.2.01 • DNS Suffix and restart.

17. LAB • Delete switch configuration. • Enable SNMP on “our lab sw”. • Give the switch suitable name, IP, GW. • Enable SNMP, put community name, SNMP version, Traps, • All steps CH:26 Cisco_3560_Guide • Save your configuration 1.1.1.1.

18. Default SNMP config.

19. Basic Component of NNM

20. Basic Component of NNM

21. Home Base • http://1.1.1.1:7510 • Dynamic views • Node status summary • Alarm browser • Dynamic summary • Discovery progress

22. Dynamic views • Path view • Neighbors view • Internet view • Network view • Node view • Segment view

23. Starting OVW • Cmd  ovw • Basic windows  Root  Internet  NW  Segment  Nodes. • “Ipmap”  service create IP sub-map hierarchy. • Relation between maps and sub-maps like parent and child.

24. Symbol properties Administrative status Operational status Unmanaged Testing Restricted disabled • Dark blue: unknown • Green: normal • Cyan: warning • Yellow: minor • Orange: major • Red: down

25. Operational status Green Cyan Yellow Orange Red

26. ovw • Help  Symbol legend • View  Zoom • View  Label • Map  Print “Unix only” • Edit  find  Location an object • Access object properties  capabilities  you can not change  general attributes  rarely changed • Map  Map snapshots • cmd  ovmapsnap

27. Ovw cont’d • Edit  add to Quick navigator

28. OVW vs. Dynamic views Dynamic Views OVW Remote administration Tomcat alarm Scaled well View  find File  print preview Poster printing • Need OS login • Edit map • NNM be installed on machine • Snapshots • Background • Quick navigator • Edi  find

29. How IP discovery? • MS discover itself, using IP, SM. DGW. • Discover DGW. • MS discover ARP cache. • SNMP community must be known. • Every 15 min, repeat polling. • “netmon” services run at background  use ICMP and SNMP over UDP to find nodes at network.

30. Control Netmon discovery • Loadhost command • Cmd  loadhosts –m 255.255.255.0 172.169.1.215 3560 172.19.1.213 nouran-pc • Useful commands: • Ovstart –c • Ovstart –v • Ovstop • Ovstatus –c

31. How to secure Home Base? • C:\Program Files\HP OpenView\bin\dvUsersManager.ovpl • It will edit in C:\Program Files\HP OpenView\tomcat\jakarta-tomcat-4.0.4\webapps\topology\WEB-INF\dynamicViewsUsers.xml • If it will not work, • C:\Program Files\HP OpenView\tomcat\jakarta-tomcat-4.0.4\webapps\topology\WEB-INF • Uncheck <security-constraint> section.

32. Day 2

33. Out line • Launcher • Network Presenter • Monitor NW Activity • Discover your network with Netmon • Controlling Netmon discovery

34. Launcher • View your network by Network Presenter “read only”. • Start launcher on windows: • Ovw  tools  hpopenview  launcher. • http://172.19.1.212/OvCgi/ovlaunch.exe • Start Launcher on Unix: • http://172.19.1.212:3443/OvCgi/ovlaunch.exe

35. Launcher Cont’d • Tasks: Access to task operation. • Configuration Event Correlation. • Configuration web reporting interface. • Information & Reports: • MIB Browser. • NNM Alarms. • Web Reporting interface. • Tools: • NW Presenter • Alarm Browser • Event corrleation • SNMP Data presenter • SNMP MIB Browser • Web Reporting

36. Launcher • Access maps from network presenter. • Open a map other than the default map. • Network presenter needs ovw map is opened. • Any change in ovw reflect in the same time in Launcher_network presenter.

37. Launcher: Network Presenter Scope Pane Control Area

38. Network presenter Vs. OVW • There are features in NW presenter, and Not available in NNM-MS. • Scoping pane • Tabular View • Scroll bar in content area • Features in ovw and not in NW presenter: • Map description dialog box • Sub map and map snapshots

39. Interaction between OVW and NW presenter For example: • When you add symbol it will be added in NW presenter. • Mange/unmanage symbol it will be reflected. • Sub map in ovw, nothing happened. • Delete submap in OVW, reflected. Note: To make launcher open other than the default map: http://cn_nouran.cisco.com/OvCgi/jovw.exe?mapname=map1 Jovw.exe is NW presenter

40. Monitor NW Activity Ch:8

41. Monitor Network Activity • Check the network connectivity. • Check a node’s network configuration. • Check the amount of network activity. • Check for alarms.

42. Remote Ping • Select a source node (click on the symbol). • Select a destination node (control-click on the symbol). • Invoke the Remote Ping dialog box from the Fault: Network Connectivity: Remote Ping menu item.

43. Test SNMP Connectivity • Select Node • Fault  Test IP/TCP/SNMP

44. Test SNMP Connectivity • Ovw  Fault  Network Connectivity  Poll Node

45. Path View • Shows the shortest path between any two nodes • Extremely useful for troubleshooting • It has Graph and table tab.

46. Other Fault Testing Tools • Status Poll • Trace Route • Capability Poll (Windows only) • Event Viewer (Windows only, ovw only) • Diagnostics (Windows only, ovw only)

47. Configuration Tools

48. Performance Monitoring Tools • Network Activity • System utilization such as CPU Load, Disk Space, or the Windows • Performance Monitor • Network Polling Statistics

49. Discover your NW with Netmon Ch:15

50. Netmon Discovers network nodes. • Ovcapsd Checks for DMI and web capabilities (Windows only) • Ovtopmd Maintains the topology and object database.
