Maybe add network plugin config to send data anywhere, then fire
wireshark and see what snmp values collectd get and how it parses it
(new versions of wireshark have builtin collectd protocol decoder)?
Kinda looks like it uses 32 bit counters, with COUNTER type its not
problem if it doesnt overflow more than once per cycle, but DERIVE
type saves NaN when counter have smaller value than last one.
