sending snmptraps

[inle]

Hi I configure snmpd in host.monitoring.fr for sending traps to my nagios server (server.monitoring.fr)

/etc/snmpd.conf
trapsink server.monitoring.fr

disk / 8900000

this value has been chosen to provoque un error when I do snmpwalk I see the error flag set to 1, but I do not know how to make this get to nagios & then to Centreon.
I did tcpdump host host.monitoring.fr but I see no messages related to snmptrap.
Any Help please?
Thanks

Good Morning.
I really do not understand, if there are so many tuto for configuring snmtraps on centreon, how is possible that nobody here can tell me how to send the traps from the client. I use debian etch as client and I want to send single traps as disk space for instance.

Thanks
