I suggest that you treat this as two distinct requirements:
- Extending the Net-SNMP agent to report the particular values
that you wish to monitor (assuming it doesn't already)
- A (separate) client application, to poll SNMP agent(s)
and log the results.
For the second, it would definitely be worth looking as RRDTool
and similar/related software (e.g MRTG, Cacti, etc) - which may
already do most of what you need.
For the first - yes, you are looking at implementing a MIB module
(or modules) for any missing information. It doesn't really matter
whether this is a subagent, or extends the master agent directly.
The MIB module code would be the same in either case.
But I'd definitely decouple the two requirements.
