I’ve had a belief for quite a while now that Linux, unlike other types of systems, was unable to produce any I/O SNMP information. I only recently found out that it was partially true – all production-level distros, such as RedHat (and Centos, for that matter) were unable to produce any output for any SNMP…
Most modern servers use Broadcom network cards. The module is called tg3 and is known to have issues. You can find in my blog several posts about weird problems with tg3.

The relationship between data types, host templates and graph templates is quite complex, and if you are to implement any non-default setup using Cacti, you better understand these relationships…
