Yeah \o/ I found what's wrong : my kernel is a grsec one, and prevent snmp to gatjer certain data :
/var/log/syslog : Oct 25 15:34:55 xxxxxx snmpd[17514]: snmpd: Cannot open /proc/net/arp
So I boot my monitored device on other kernel, and now the MIB is correctly updated.
Thanks everyone, cannot made it without your help, learn a lot.

Ok so, I followed http://www.observium.org/wiki/NetSNMPd_Client_Configuration and take pieter snmpd conf file, and still have the same issue. When I restart snmpd service, i've got a big spike on the graph, but after that nothing else than 0 bit.

There was a request for "my basic snmpd.conf":

Are you monitoring more than one device?

ifOutOctets and ifInOctets seem to have valid values
But when i run the same command again, the values are exactly the same, althought this a server with huge traffic.
MIB seems not been updated...
