I installed Check_Mk 2.0.0.p1 cee version and the EC receive the snmp traps judging by the mkeventd.log. I have enabled the debug mode and the errors that I have are:
unknown securityEngineID
StatusInformation: {‘errorIndication’: UnknownSecurityName(‘Unknown SNMP security name encountered’)
Trap (v3) dropped from XXX.XX.X.XXX: Unknown credentials (msgUserName: Test)
The configuration on the sender side is the same as the configuration on the receiver side (check_mk).
