I have issues with receiving traps in OpManager as no traps are currently displayed in OpManager v12.2.

OpManager is installed on a Linux Centos 7 server.

The following debugging steps has been taken:

1) A tcpdump on port 162 on the server running OpManager shows that the traps are being received correctly through the port so no issues with Firewalls 

2) All devices are set with the correct credentials.

3) Trap definitions has been loaded through the mib files and enabled through the GUI.

4) Verified the database (event and event_dd_MM_YY tables) whether traps are listed (unsolicited or not) and they are not listed in the table.

Please advise how I can proceed further with the debugging or if there are any configurations that I missed.

Thanks
