You can try creating a /etc/snmp/snmpd.conf file with only this line in it:

rocommunity public 192.168.1.0/24

If you want, change "public" to a (secret) community name you want,
and change the IP range to the IP range you want to allow to query
your server via SNMP. (Note that localhost is not included there, so
include another line for 127.0.0.0/8 if you want queries from
localhost.)

This will expose the whole MIB to any host on that IP range using that
community name, and it is a good starting point for your
configuration.

This should be enough to get you started. However, this is a very
permissive configuration (although it doesn't allow writes which could
be dangerous in terms of allowing other hosts to change settings on
your host). It's OK for me, but it might not be considering your
security policies. If you need something more restrictive than that,
read the snmpd.conf manual page very carefully to establish what
exactly you need.

HTH,

Unfortunately this didn't work. Although I could see a whole lot of MIB's now, Cacti still doesn't graph the network interface

The error I'm getting is :

Data Query [SNMP - Interface Statistics] Reload Associated Query
This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.


When I enable debug mode for the interface, this is all I get:
