How do I add a MIB to the agent?
-------------------------------
How do I add functionality?
--------------------------

  While simply adding a file to the MIB directory (and possibly tweaking
  the list of MIBs to load) is sufficient for the tools, unfortunately
  extending the functionality of the agent to include this is not so simple.
  In fact, the agent makes little or no use of these files, and will work
  quite happily without them.  All the information about the syntax and
  scope of the variables supported is hardwired into the implementation
  of the agent.

  There are a number of alternative ways to add functionality for a new
  MIB to the agent.

  Firstly, it is possible that the agent distribution already includes
  the desired functionality, but this has simply not been configured in
  to the running version.  This is done using the configure option
                --with-mib-modules="list"
  (where "list" is a space-separated list of modules to include) then
  recompiling the agent.
  Note that some functionality concerned with monitoring and managing
  unix hosts is included in the UCD extension modules, which are located
  within the 'private' branch of the MIB tree.  This is covered in a later
  question in this FAQ.

  Secondly, it is possible for the agent to run commands or shell scripts
  in response to queries.  These can obtain and report the necessary
  information, or perform actions as required.
  Detailed information and examples are provided in the snmpd(8) and
  snmpd.conf(5) manual pages, and the EXAMPLE.conf file.
  This is known as "pass-through" support.

  Thirdly, it may be possible to link another agent (which already
  supports the desired MIB), as a "subagent" of the Net-SNMP master
  (or vice versa).  The possibilities here are SMUX, AgentX or proxied
  SNMP (see the next question but one).

  Finally, the agent itself can be extended to support additional MIB
  groups, by writing the necessary C code, and including this within
  the main agent - either statically compiled in, or dynamically loaded.
  This is covered further in the next section.

    Note that there is no visible difference between 'pass-through'
  MIB support, subagents, and modules implemented within the main agent
  itself. Tools querying the agent will see a single MIB structure.
