### 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}
