[AGENT++] Help implementing common oids

[rinn2883]

Hi

I want to provide some common oids (cpu, memory, iterfaces) from a linux 
system
and extend it with some custom oids to read gios.

The examples are rather complex for a novice.
Just an example with SNMPv3 and sysDescr would be nice :-D haha.
SNMP has been around for a long time, so do I have to implement these 
common oids myself?
Or can I get them somewhere?
I already have the MIBs, I'm talking more about the agent++ 
implementation for them.
I believe if I can look at the implementation of the common oids, i can 
figure out how to do
the gpio oids myself.

One other small question. I think i don't need the MIB on the embedded 
machine?
The MIB is more for clients, so that they know what data they are getting.
The embedded device has only 40MB of space and I dont want to add the 
MIBs if I
don't have to.

Kind regards
