Functions

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

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}

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.

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

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.

stop_sub_agent(SubAgent) -> ok | no_such_child

SubAgent = pid()

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