There are basically two ways to extend the agent.

One way is use a fixed-format MIB output, which is the approach
used by the "extend" (and similar) directives.   The advantage is
that the agent script doesn't have to do anything special, and can
be ignorant of SNMP completely.   The disadvantage is that the
client side has be a little more flexible, and adapt to this fixes format.

The alternative is to have a specific MIB, more tightly focused on
the precise requirements of the client side.  That makes things
simpler for the client, but does mean that the agent has to do a
bit more work to match this MIB.

It does sound as if that's the way you'll need to go.
That doesn't mean you have to descend into the murky
depths of writing a fully-fledged C module.  Have a look
at the "pass" directive - that ought to be sufficient.
