Why am I unable to view trap alarms in OpManager MSP?

SNMP Traps are sent by the managed devices to the OpManager MSP server for notifying important events. For the received traps to be processed in OpManager MSP , they need suitable SNMP Trap Processors. The SNMP Traps that are processed can be found under Alarms > Trap Alarms.

Unsolicited Traps (mouse hover action). To be alerted of these unsolicited traps, you need to create appropriate trap processors.

Reason #6:Trap Processor might have issues with the processing criteria.
Solution:The SNMP Trap Processors created might have a criteria mismatch. This is due to

• SNMP version (v1, v2 & v3) mismatch - Version of SNMP Trap received does not match with the version of trap processor created
• Manual errors in setting Match Criteria.

In the above cases, the SNMP Trap Processor has to be modified accordingly.

If the issue persists, follow the steps below to check whether the traps are received by OpManager MSP :

1. Go to Settings > General Settings > System Settings.
2. Under the Logging tab, enable the Debug Prints.
3. Now send test traps to the OpManager MSP server.
4. Once the test traps are sent to OpManager MSP , stop the OpManager MSPservice.
5. Go to the bin folder under the installation directory and run the MibBrowser.bat file as administrator.
6. In the MibBrowser window, go to View > Trap Viewer.
7. In the TrapViewer window, click on Start, and check if the traps are received by the TrapViewer.
8. On checking the trap viewer,
   1. If the traps are not displayed, test the traps from the end device and configure the end device to send the traps to the OpManager MSP server.
   2. If the traps are displayed, drop a mail to msp-opmanager-support@manageengine.com.
