snmpa_supervisor
(snmp)A supervisor for the SNMP agent Processes
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).
Functions
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
.
db_dir
is mandatory.
See configuration parameters for a description of the options.

in config is mandatory.
See snmp config for a description of the options.
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.
If the supervisor is not running, the function fails with the
reason badarg
.
stop_sub_agent(SubAgent) -> ok | no_such_child
SubAgent = pid()
Stops the sub-agent on the node where the function is
