[CentOS] can't get Ethernet SNMP information

Hi all,

I hope someone can help me with this one.

I'm trying to graph all traffic on the localhost's network card with Cacti.
>From what I understand I should use SNMP to query the traffic, but I can't
seem to get SNMP info for the network interface.

I have installed all the necessary snmp tools, "yum install snmpd net-snmp
net-snmp-utils net-snmp-devel net-snmpt-libs " and then started snmpd
(/etc/init.d/snmpd start)

running snmpwalk, I get the following:

snmpwalk -v 1 -c public localhost
SNMPv2-MIB::sysDescr.0 = STRING: Linux localhost 2.6.18-92.1.10.el5xen #1

HOST-RESOURCES-MIB::hrSystemUptime.0 = Timeticks: (130862) 0:21:48.62
End of MIB

Yet, when I try and query the "SNMP - Interface Statistics", it doesn't
return any information.

Running debug for the interface in Cacti, I get the following:

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.'
+ No SNMP data returned
+ Found data query XML file at
+ Found data query XML file at
+ Found data query XML file at

Can someone please help me with this one?

Kind Regards
