That's a bit vague.
What exactly are you interested in?
Client applications? The SNMP agent (in broad terms)?
The processing of an individual requested varbind?
Subagents?

When? As soon as you like?
Where?
For following client applications, the simplest is probably to run one
of the clients within a debugger, and single-step through the code.
For following the workings of the agent, it's probably simpler to start
by turning on some selected debugging ("-D{token}") and watch what
happens when the agent receives a request.
Have a look through the code under 'agent' for mention of DEBUGMSG,
and turn on something that looks interesting.
(Hint - do *not* turn on full debugging. You'll drown in the output!)
