First, thanks for this module, it has helped me a lot. I have implemented an agent with multiple variables and tables and it seems to work fine, although to implement the tables, it was more work than I have originally assumed (I am not using the generic instrumentation nor ecto).

Now I need to implement sending SNMP notifications/traps and the library does not seem to provide much help with this. The config files it generates seem to lack support for notifications.

Is there any guidance how to support notifications on top of this library?

MIB compiler generates a lof of instrumentation functions, types, ecto types, etc

We want to implement the following architecture:

• MIB compiler compiles .mib file into mib record and makes it a module attribute
• MIB generators implements before_compile callbacks and generates whatever they want from this
• List of generators can be changed through Mib.__using__ macro option

Rationale

SNMP agent configuration possible errors are numerous and may be complex (dependent, conflicting options, etc)
Actually, agent configuration stops at first error. It could be better to have a full report of all errors when starting the agent.

Expected

Agent configuration is represented as an Ecto schema, so that we can leverage changeset mechanisms for validating and reporting errors.

The Erlang SNMP allows to map the MIB objects to instrumentation functions through the xxx_MIB.funcs like this:
{myName, {ex1, my_name, []}}.

The MIB compilation step in elixir-snmp should map the camelCase object names to snake_case automatically.
When the instrumentation function names are left in camelCase as in the MIB, mix credo reports readability issues like this:

┃ [R] ↗ Function/macro/guard names should be written in snake_case.
┃ apps/snmp_agent/lib/snmp_agent/snmp/mib/strouter.ex:43:7 #(SnmpAgent.Mib.StRouter.inputsTable)

I think the current library fails if using "AUGMENTS" in an mib? I wanted to implement IF-MIB in my app, so I created a stub something like:

defmodule SnmpAgent.Mib.If do
  use Snmp.Mib, name: "IF-MIB"
end

Then added IF-MIB and IANAifType-MIB into my local mibs directory. This fails with an error:

If I replace the "AUGMENTS { ifEntry }" in IfXEntry, then it compiles (and gives me errors about missing definitions)

So I speculate that it's something to do with the thing being augmented being described in the same file? However, I'm not sure how to progress to resolve this? Any guidance?
