NAME

       snmp_target_mib - Instrumentation Functions for SNMP-TARGET-MIB

DESCRIPTION

       The  module  snmp_target_mib implements the instrumentation functions for the SNMP-TARGET-
       MIB, and functions for configuring the database.

       The configuration files are described in the SNMP User's Manual.

DATA TYPES

       transportDomain() = transportDomainUdpIpv4 | transportDomainUdpIpv6
       transportAddressIPv4() = [integer()], length 4
       transportAddressIPv6() = [integer()], length 8
       transportAddressMask() = [integer()], length 0 (default), 6 (IPv4) or 10 (IPv6)

EXPORTS

       configure(ConfDir) -> void()

              Types:

                 ConfDir = string()

              This function is called from the supervisor at system start-up.

              Inserts all data in the configuration files into the database and destroys all  old
              rows  with  StorageType volatile. The rows created from the configuration file will
              have StorageType nonVolatile.

              All snmp counters are set to zero.

              If an error is found in the configuration file, it is reported using  the  function
              config_err/2  of  the  error  report module, and the function fails with the reason
              configuration_error.

              ConfDir is a string which points to the directory where the configuration files are
              found.

              The configuration files read are: target_addr.conf and target_params.conf.

       reconfigure(ConfDir) -> void()

              Types:

                 ConfDir = string()

              Inserts  all data in the configuration files into the database and destroys all old
              data, including the rows with StorageType nonVolatile. The rows  created  from  the
              configuration file will have StorageType nonVolatile.

              Thus,  the data in the SNMP-TARGET-MIB, after this function has been called, is the
              data from the configuration files.

              All snmp counters are set to zero.

              If an error is found in the configuration file, it is reported using  the  function
              config_err/2 of the , and the function fails with the reason configuration_error.

              ConfDir is a string which points to the directory where the configuration files are
              found.

              The configuration files read are: target_addr.conf and target_params.conf.

       set_target_engine_id(TargetAddrName, EngineId) -> boolean()

              Types:

                 TargetAddrName = string()
                 EngineId = string()

              Changes the engine id for a target in the snmpTargetAddrTable. If notifications are
              sent as Inform requests to a target, its engine id must be set.

       add_addr(Name, Ip, Port, Timeout, Retry, TagList, Params, EngineId, TMask, MMS) -> Ret
       add_addr(Name, Domain, Ip, Port, Timeout, Retry, TagList, Params, EngineId, TMask, MMS) ->
       Ret

              Types:

                 Name = string()
                 Domain = transportDomain()
                 Ip = transportAddressIPv4() | transportAddressIPv6() (depends on  the  value  of
                 Domain)
                 Port = integer()
                 Timeout = integer()
                 Retry = integer()
                 TagList = string()
                 ParamsName = string()
                 EngineId = string()
                 TMask = transportAddressMask() (depends on Domain)
                 MMS = integer()
                 Ret = {ok, Key} | {error, Reason}
                 Key = term()
                 Reason = term()

              Adds a target address definition to the agent config. Equivalent to one line in the
              target_addr.conf file.

       delete_addr(Key) -> Ret

              Types:

                 Key = term()
                 Ret = ok | {error, Reason}
                 Reason = term()

              Delete a target address definition from the agent config.

       add_params(Name, MPModel, SecModel, SecName, SecLevel) -> Ret

              Types:

                 Name = string()
                 MPModel = v1 | v2c | v3
                 SecModel = v1 | v2c | usm
                 SecName = string()
                 SecLevel = noAuthNoPriv | authNoPriv | authPriv
                 Ret = {ok, Key} | {error, Reason}
                 Key = term()
                 Reason = term()

              Adds a target parameter definition to the agent config. Equivalent to one  line  in
              the target_params.conf file.

       delete_params(Key) -> Ret

              Types:

                 Key = term()
                 Ret = ok | {error, Reason}
                 Reason = term()

              Delete a target parameter definition from the agent config.
