Hi and thanks for the question.
You said you are sure your server is configured to send SNMP traps to OME. So that's a start.
You said the SNMP alert is _not_ showing up in the OME alert console.
You can try to use wireshark to see if the OME server is getting the alert from the server. Or you can try the Dell Troubleshooting tool and see if the SNMP traffic is hitting that tool.
Assuming you have taken care of any firewall issues for the SNMP port.
Thx,
Rob
