  1. 1. Welcome to a free OpManager training session
  2. 2. Can you hear me? Can you see the presentation? Please confirm by commenting in the webinar chat panel
  3. 3. Trainer Srikanth V Techincal Support Engineer
  4. 4. Part 4 Fault management and IT automation
  5. 5. Agenda  Alarm severity levels  Threshold violation alarms  Other alarms : VMWare; Event logs; SNMP traps and Syslogs  Notifications  Using an IT workflow to remediate problems
  6. 6. Severity Color code Attention Trouble Critical Service down Clear Alarm severity levels
  7. 7. Device down Interface down Severity: predefined
  8. 8. Process down Service down URL down Severity: predefined
  9. 9. Event log Syslog SNMP trap Severity: configurable
  10. 10. • Configuring threshold values on an individual device • Configuring consecutive times • Configuring rearm value to clear fault alarms • Using device templates to configure thresholds globally based on device type Threshold-based alarms
  11. 11. Alarms for inventory changes o vMotion o Host added/removed o Host or VMs connected/disconnected o VMs powered on/off o VMs orphaned o Scheduled task removed o Etc. Querying more events from the Vcenter server / ESX host VMware events
  12. 12. Event log alarms Prerequisites o Check if WMI and RPC services are enabled on the Windows servers o Default WMI ports: 135 & 445, 5000 to 6000 (TCP) • Configuring event logs for a Windows server in OpManager • Ignoring a specific event log from a Windows server • Creating custom Eventlogs
  13. 13. SNMP trap alarms OpManage r Trap- Receiver Router Switch Firewall Server SNMP Agent Management Definitions Management Database Trap (162) 5things you should know about SNMP traps in OpManager 1. Unsolicited traps 2. Loading traps from MIB files 3. Filtering trap messages 4. Customizing trap messages 5. Forwarding trap messages to another NMS platform
  14. 14. #1 Unsolicited traps I have configured a Router to forward SNMP traps to OpManager's server. However I don't get to see an alarm? How do I fix this? Things to verify :  Verify whether the Router is added to OpManager  Verify whether the 'Trap rule' is available for the respective event  Verify whether the trap event is listed under 'Unsolicited traps' Solution : Identify the event from the 'Unsolicited traps' and add a new trap rule
  15. 15. #2 Loading traps from MIB files Prerequisites • Vendor MIBs Mibs • What is a mib file? • How to obtain the mib file? • Uploading the mib files in OpManager • Loading trap from mibs Examples • Loading traps for compaq proliant servers using the vendor mib CPQHLTH-MIB I don't want to manually add the trap rules one by one. How do I upload the trap rules in a bulk?
  16. 16. #3 Filtering the trap messages I have a Windows server added to OpManager. It triggers 100s of trap events with various messages from x.x.x.x OID. However I want to filter the trap event only if the priority is 'critical' and clear the event automatically when the priority is 'low'? How do I achieve this? Know • What is a varbind? • How to identify the varbinds from trap event? Solution : Use 'match criteria' to filter and clear the trap alarms based on 'varbinds'
  17. 17. #4 Customizing the trap messages
  18. 18. #5 Forwarding trap messages 162 NMS server 162 public 1. Forwarding the received SNMP traps to the desired destination. 2. Converting the alerts received in OpManager into a trap alert to a desired destination. 1 2
  19. 19. Syslog alarms Prerequisites : o Configure devices to forward syslog events to OpManager's server o Default ports: 514 & 519 (UDP); configurable • Creating a syslog rule o Syslog receiver • Using facility name, severity, or match text to filter and clear syslog alarms (regex format) • Identifying the syslog flow rate from OpManager • Forwarding syslog messages to another NMS platform
  20. 20. Profile Type • Email/SMS • Run system command • Run a program • Log a ticket • Send syslogs/traps Criteria • Missed polls • Hardware condition • Threshold violation • Agent status • Severity level Device Selection • Individual devices • Category • Business views Schedule • Time Window • Delayed Trigger • Recurring Trigger Preview • Test Action • Save and Execute Notification profiles in OpManager
  21. 21. #1 Email notification Steps : 1. Configure mail server settings 2. Create a notification profile for 'email'; - Select the required 'alarm criteria'; - Associate the profile with 'required devices'; I want to receive an email notification for all service down alarms. How do I configure this?
  22. 22. #2 Log a ticket Steps : 1. Setting up the integration with ServiceDesk Plus 2. Create a notification profile for 'log a ticket'; - Select the 'category, group and technician'; - Select the required 'alarm criteria'; - Associate the profile with 'required devices'; I want OpManager to create a ticket in ServiceDesk Plus whenever a problem is detected in the interface. The ticket should have the fields like category, group and technician filled automatically.
  23. 23. Automate fault management with IT workflow Create a workflow Associate devices Schedule/trigger tasks 1 2 3
  24. 24. Free up disk space on the server
