Opmanager Workshop - Middle East

  1. 1. ITOM Workshop – Dubai OPMANAGE R
  2. 2. Optimum visibility of your Network Infrastructure by Sharath Babu
  3. 3. OpManager • Discover and add devices into OpManager. • Use rule engine to automate monitoring & setting up notifications. • Monitor availability & performance • Custom SNMP & WMI monitors • Monitor virtual server performance • Set alarms severity and threshold violations • Network maps & reports Agenda
  4. 4. Prerequisite for installing OpManager- System requirements Quad core processor or higher • MSSQL • PGSQL 40 GB8 GB • Window s • Linux http://opmanager.helpdocsonline.com/hardware-and-software-requirements
  5. 5. Adding devices in OpManager ...
  6. 6. Discovery Cycle - Layer2 Discovery - CSV import - IP range - CIDR - Add device - vCenter/host - Hyper-V - XenServer - UCS Inputs Credentials Automate configurations - service monitors - process monitors - application monitors - grouping devices - notifications - automate device addition - update device properties - update interface properties - pre-define network interface - admin/operational status Rules Interface Schedule - SNMP v1/v2/v3 (n/w devices) - WMI/SNMP for Windows - Telnet/SSH/SNMP for Linux -vCenter root access for VMware -Citrix credentials(Xen servers) -UCS credentials(Cisco UCS)
  7. 7. Central IT Building Building 1 Building 2 Remote Campus
  8. 8. Input Different ways of adding devices in OpManager Step 01
  9. 9. • CSV • vCenter/ESX-host/Hyper-V/XenServer/UCS • Layer 2 Discovery • Add device via Trap • Ip Range Input Credentials Rules Interface Schedule Input Credentials Rules Interface Schedule
  10. 10. Credentials Adding credentials for SNMP, WMI, Telnet, SSH, VMware, etc Step 02
  11. 11. Input Credentials Rules Interface Schedule
  12. 12. Rule Engine Automate configurations with Rule Engine Step 03
  13. 13. Task 3 Task 2 Task 1 Every time I add a SQL server, I set up the same set of services, processes, and application monitors. How do I automate this in OpManager? I have grouped all MSSQL Servers in a 'Business view' for our Riyadh site, and more servers will be added in the future. Can I place these servers in the Riyadh group automatically? I've set up a notification profile to trigger an email notification for service down alarms. Can I assign this notification profile automatically when a server is added to OpManager? SQL server Use Case : Automate configurations with 'Rule Engine'
  14. 14. Interface Discovery Add only the managed interfaces for monitoring Step 04
  15. 15. Input Credentials Rules Interface Schedule
  16. 16. Use Case : Add only the managed interfaces for monitoring with 'Interface discovery'
  17. 17. Discovery schedule & reports Automatically adding devices with discovery schedules Step 04
  18. 18. Device properties - RAM size - Hard disk size - Exchange version, etc Use Case : Update interface/device properties with 'Discovery schedule' Interface properties - Name - Speed - Description - Admin/operational status,etc
