NAME

       snmpc - SNMP MIB compiler frontend

Synopsis

       snmpc [options] file.mib | file.bin

Description

       The snmpc program provides a way to run the SNMP MIB compiler of the Erlang system.

       snmpc compiles an SNMP MIB file. See compile/1,2 for more information.

       It can also be used to generate a header file (.hrl) with definitions of Erlang constants for the objects
       in the MIB. See mib_to_hrl/1.

Compiler options

       The following options are supported (note that most of these relate to the compilation of the MIB file):

       •   --help - Prints help info.

       •   --version - Prints application and mib format version.

       •   --verbosity verbosity - Print debug info.

           verbosity = trace | debug | log | info | silence

           Defaults to silence.

       •   --warnings | --W - Print warning messages.

       •   --wae | --Werror - Warnings as errors. Indicates that warnings shall be treated as errors.

       •   --o  directory  -  The  directory where the compiler should place the output files. If not specified,
           output files will be placed in the current working directory.

       •   --i Directory - Specifies the path to search for imported  (compiled)  MIB  files.  By  default,  the
           current working directory is always included.

           This option can be present several times, each time specifying one path.

       •   --il  Directory  -  This option (include_lib), specifies a list of directories to search for imported
           MIBs. It assumes that the first element in the directory name corresponds to an OTP application.  The
           compiler  will  find  the  current  installed  version. For example, the value ["snmp/mibs/"] will be
           replaced by ["snmp-3.1.1/mibs/"] (or what the current version may be  in  the  system).  The  current
           directory and the "snmp-home"/priv/mibs/ are always listed last in the include path.

       •   --sgc  -  This  option  (skip group check), if present, disables the group check of the mib compiler.
           That is, should the OBJECT-GROUP and the NOTIFICATION-GROUP macro(s) be checked  for  correctness  or
           not.

       •   --dep  -  Keep  deprecated  definition(s).  If  not  specified  the  compiler  will ignore deprecated
           definitions.

       •   --desc - The DESCRIPTION field will be included.

       •   --ref - The REFERENCE field will be included.

       •   --imp - The IMPORTS field will be included.

       •   --mi - The MODULE-IDENTITY field will be included.

       •   --mc - The MODULE-COMPLIANCE field will be included.

       •   --ac - The AGENT-CAPABILITIES field will be included.

       •   --mod module - The module which implements all the instrumentation functions.

           The name of all instrumentation functions must be the same as the  corresponding  managed  object  it
           implements.

       •   --nd  -  The  default  instrumentation  functions  will  not  be  used  if  a  managed object have no
           instrumentation function. Instead this will be reported as an error, and the compilation aborts.

       •   --rrnac - This option, if present, specifies that the  row  name  assign  check  shall  not  be  done
           strictly according to the SMI (which allows only the value 1).

           With  this  option, all values greater than zero is allowed (>= 1). This means that the error will be
           converted to a warning.

           By default it is not included, but if this option is present it will be.
