NAME

       snmpa_supervisor - A supervisor for the SNMP agent Processes

DESCRIPTION

       This is the top supervisor for the agent part of the SNMP application. There is always one
       supervisor at each node with an SNMP agent (master agent or sub-agent).

EXPORTS

       start_sub_sup(Opts) -> {ok, pid()} | {error, {already_started, pid()}} | {error, Reason}

              Types:

                 Opts = [opt()]
                 opt() = {db_dir, string()} | ...

              Starts a supervisor  for  the  SNMP  agent  system  without  a  master  agent.  The
              supervisor  starts  all involved SNMP processes, but no agent processes. Sub-agents
              should be started by calling start_sub_agent/3.

              db_dir is mandatory.

              See configuration parameters for a description of the options.

       start_master_sup(Opts) -> {ok,  pid()}  |  {error,  {already_started,  pid()}}  |  {error,
       Reason}

              Types:

                 Opts = [opt()]
                 opt() = {db_dir, string()} | {config, ConfOpts()} | ...
                 ConfOpts = [conf_opts()]
                 conf_opts() = {dir, string()} | ...
                 Reason = term()

              Starts  a  supervisor for the SNMP agent system. The supervisor starts all involved
              SNMP processes, including the master agent. Sub-agents should be started by calling
              start_subagent/3.

              db_dir is mandatory.

              dir in config is mandatory.

              See snmp config for a description of the options.

       start_sub_agent(ParentAgent,Subtree,Mibs) -> {ok, pid()} | {error, Reason}

              Types:

                 ParentAgent = pid()
                 SubTree = oid()
                 Mibs = [MibName]
                 MibName = [string()]

              Starts  a  sub-agent on the node where the function is called. The snmpa_supervisor
              must be running.

              If the supervisor is not running, the function fails with the reason badarg.

       stop_sub_agent(SubAgent) -> ok | no_such_child

              Types:

                 SubAgent = pid()

              Stops the sub-agent on the node where the function is called. The  snmpa_supervisor
              must be running.

              If the supervisor is not running, the function fails with the reason badarg.
