I hope this is an appropriate forum.

I'm setting up MRTG on a server, and have got it working for the most part. When you view the page, I'm getting the following at the top.

Traffic Analysis for 3 -- Not defined (edit /etc/snmp/snmpd.conf or use snmpconf)
System: Not defined (edit /etc/snmp/snmpd.conf or use snmpconf) in Not defined (edit /etc/snmp/snmpd.conf or use snmpconf)
Maintainer: root <root@localhost> (configure /etc/snmp/snmp.local.conf or use snmpconf)
Description: eth1
ifType: ethernetCsmacd (6)
ifName: eth1
Max Speed: 100.0 Mbits/s

The statistics were last updated Sunday, 2 September 2007 at 15:15,
at which time 'Not defined (edit /etc/snmp/snmpd.conf or use snmpconf)' had been up for 25 days, 1:29:44.

I'm not quite sure what I'm supposed to edit within the /etc/snmp/snmpd.conf file, and am hoping someone can guide me.
