A Processor for the selected trap is added, and is listed under the Traps tab.ĭespite configuring the SNMP Trap Processor in OpManager, you might still not see the alarms based on traps.Select the required trap variable, and click Add.From the list of MIBs, select the MIB from which you would like to load the trap variable.Click on Load Traps From Mibs at the top of the page.Go to Settings → Monitoring → SNMP Trap Processors. All the configured processors are listed here.Click Save for the configuration to take effect.įollowing are the steps to load the traps from various MIBs:.Select the variable bindings, the condition, and the string to be matched. Rearm Criteria: Similarly, select the appropriate radio button to match the rearm conditions.Match Criteria: Select the appropriate radio button to either match any one or all the conditions that you specify.Message: Select the required message variables.This option is useful if the trap is forwarded from another source. Source: Append the Varbinds to be matched if required.Trap OID: For devices with SNMP v3 version, select the trap oid from the MIB using the Select button.Rearm Criteria: Similarly, select the appropriate radio button to match the rearm conditions.Match Criteria: Select the appropriate radio button to either match any one or all the conditions that you specify.Source: Append the Varbinds to be matched if required.You can match the entity too by appending the VarBind number in this field to generate separate alarms for the failed components. The Varbinds containing more details on the trap will have information on the failed components (entities like CPU, Temperature etc). Failure Component: This option is useful when you deal with a single trap OID that has multiple failure components.Trap OID: For devices with SNMP v2c version, select the trap oid from the MIB using the Select button.Specific Type: When Generic Type is set to Enterprise a specific trap ID s identified.Generic Type: Cold Start, Link Up, Enterprise, etc.SNMP Trap Version:Select the version (SNMP V1/V3).Name: Configure a name for the new trap processor.Configure/Modify the following properties:.Click the TrapParser name/ Edit icon to modify an existing one.Go to Settings → Monitoring → SNMP Trap Processors.The following actions can be done by clicking the relevant icon:Įnable or disable trap processing: Click to enable/disable trap processingĭelete processor: Delete the Trap Processor The traps that are not processed are listed under 'Unsolicited Traps'. Trap Processor converts the cryptic message to human-readable alarm.Ĭonfigure OpManager to process the traps that are not processed out-of-the-box and convert them into alarms. Once a matching trap is found, an alert is generated. When a trap is received from a managed device, the match criteria in the parser determines whether a specific trap matches the conditions specified in the Trap Processor. OpManager enables you to process the traps from the managed devices.

Enterprise specific: Vendor specific error conditions and error codes.egpNeighborloss: Agent cannot communicate with its EGP (Exterior Gateway Protocol) peer.Authentication fails: This happens when an SNMP agent gets a request from an unrecognized community name.Linkup or Linkdown: A network interface card (NIC) on the agent either fails or reinitializes.Coldstart or Warmstart: The agent reinitialized its configuration tables.SNMP traps are alerts generated by agents on a managed device. Traps are cryptic messages of a fault that occurs in an SNMP device.
