The pending state is ok, as you have set the check_period to none, which
i suppose contains no timeslots. The service will never be actively
checked.

Notice the mentioned check_period above? You configured two of them, get
rid of one of them (it's confusing).

Nagios receives an external check result and tries to match it to one of
it's configured services. Services are uniquely identified by the
associated host and the service name.

Your configuration is for host "device_name" and service "TRAP", the
external check result is for host "system_name" and service "TRAP". No
match here (and that's what Nagios complains about in it's warning
message).
