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]  [image: Reload Associated
Query]<http://saturn.softdux.com/graphs/graphs_new.php?action=query_reload&id=1&host_id=1>
 This
data query returned 0 rows, perhaps there was a problem executing this data
query. You can run this data query in debug
mode<http://saturn.softdux.com/graphs/host.php?action=query_verbose&id=1&host_id=1>to
get more information.


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