Module Summary

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.

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

MibName = [string()]
