That's a difficult question.
+
That's not easy to answer in general.
 +
 
 +
If there's an existing agent that already implements the desired new
 +
MIB, then it makes sense to re-use that, via whatever extension protocol
 +
it might support.  Ideally, this would be an AgentX sub-agent, since the
 +
AgentX protocol is deliberately designed for this purpose, and provides
 +
a fuller and more reliable mechanism than either SMUX or proxied SNMP.
 +
But if the target subagent only supports SMUX or basic SNMP, then that
 +
would dictate the extension protocol to use.
 +
 
 +
Implementing the module directly within the main agent (or via dlmod)
 +
is probably the most efficient and reliable (since there's minimal
 +
overheads between the code implementing the MIB module, and the agent
 +
framework).  But it does assume that there's a suitable mechanism for
 +
retrieving the necessary information.
