- 8. Agenda • Alarm severity levels • Threshold violation alarms • VMware events • Event log alarms • Syslog alarms • SNMP trap alarms • Notifications • Using an IT workflow to automate repetitive or scheduled tasks • Tips and tricks • Questions
- 10. Severity Color code Attention Trouble Critical Service down Clear
- 11. Device down Interface down Severity: predefined
- 12. Process down Service down URL down Severity: predefined
- 13. Event log Syslog SNMP trap Severity: configurable
- 15. • Configuring threshold values on an individual device • Configuring consecutive times • Configuring rearm value to remove cleared faults • Using device templates to configure thresholds globally based on device type Threshold-based alarms
- 16. VMware events
- 17. 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. VMware events
- 18. Event log alarms
- 19. 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 • Configuring OpManager to handle event floods (http://help.opmanager.com/stopping-event-flood) • serverparameters.conf (OpManager/conf/OpManager) • EVENTS_PER_HOUR 1000 • EVENT_FLOOD_SEVERITY Critical • Creating a custom event log
- 20. Syslog alarms
- 21. 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 • 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 OpManager events (as syslogs) or received syslog messages to another NMS platform
- 22. SNMP trap alarms
- 23. Prerequisites o Configure devices to forward SNMP trap events to OpManager's server o Default port: 162 (UDP); configurable • Creating an SNMP trap processor rule • Using the failure component to combine SNMP traps received from two different OIDs • Using varbinds to filter and clear SNMP trap alarms • Loading SNMP traps from vendor MIBs • Processing unsolicited traps • Configuring OpManager to handle event floods • Forwarding OpManager events (as traps) or received SNMP traps to another NMS platform SNMP trap alarms
- 24. Notifications
- 25. Notification cycle Profile type - Send email or SMS - Send modern SMS - Run system command - Run program - Log a ticket - Web alarm - Syslog - Trap Alarm criteria - Device down - Service down - Hardware fault - Threshold violation - Virtual device fault - UCS fault Device selection - Category - Business view - Devices Schedule - All the time - Selected time window - Delayed trigger - Recurring trigger Preview - Verify inputs - Add a profile
- 26. SMS: modem/app SMS/Clickatell/email-based Log a ticket Web alarm Run system command Run a program Syslog SNMP trap Email Notification types
- 28. • Instant device check • Test SNMP service • Export/ Import available templates o site to site o https://resources.manageengine.com/resources/forum/opmanager/workflows IT workflow automation Create a workflow Associate devices Schedule/trigger tasks 1 2 3
- 29. Tips and tricks
- 30. Tips and tricks • Configure device dependencies to stop polling a dependent device when its parent device is down • Suppress known alarms from an individual device • Configure the downtime scheduler and stop polling devices during maintenance windows • Configure alarm escalation and notify the super admin when a critical alarm is not cleared within a given amount of time • Unified alarm console • Widgets for alarms
