SNMP TRAP not displayed in NAGIOS

Hello,

I have configured a QNAS to report SNMP TRAP to my NAGIOS server, but nothing appears in NAGIOS.
I compiled the MIB and added the reference in /etc/snmp/snmptt.ini
I copied the MIB files in /usr/share/snmp/mibs/

When a TRAP is sent to NAGIOS, I have the following:

in /var/log/messages:

My NAGIOS CFG file is:

define host{
        use             windows-server  ; Inherit default values from a template
        host_name       taurusfs  ; The name we're giving to this host
        alias           TRAP QNAP ATELIER NUMERIQUE
        address         128.1.101.162
        hostgroups      Divers_Hosts
        }

define hostgroup{
        hostgroup_name  Divers_Hosts    ; The name of the hostgroup
        alias           Devices ; Long name of the group
        }

define service{
 host_name       taurusfs
 use             snmptrap-service
}

Thank you for helping me.
