The snmp_supervisor is the supervisor for the SNMP
application. There is
always one supervisor at each node with an SNMP agent (master agent or
subagent).
start_sub()
start_sub(Opts) -> {ok, pid()} | {error,
{already_started, pid()}} | {error, Reason}
Types:
Opts = [opt()]
opt() = {priority, Prio}
Starts a supervisor for the SNMP agent system without a
master agent. The supervisor starts all involved SNMP
processes, but no agent processes. Subagents should be
started by calling start_subagent/3.
Prio is an Erlang priority. All SNMP processes
use this priority. Default is the same as default in
the Erlang runtime system.
start_master(DbDir,ConfDir)
start_master(DbDir,ConfDir,Opts) -> {ok, pid()} | {error,
{already_started, pid()}} | {error, Reason}
Types:
DbDir = string()
ConfDir = string()
Opts = [opt()]
opt() = {mibs, Mibs} | {net_if, NetIfModule} | {priority,
Prio} | {name, Name}
Mibs = [MibName]
MibName = [string()]
NetfModule = atom()
Name = {local, atom()} | {global, atom()}
Starts a supervisor for the SNMP agent system. The
supervisor starts all involved SNMP processes, including the
master agent. Subagents should be started by calling
start_subagent/3.
DbDir is a string including a trailing directory
delimiter, which points to the directory where the
database files sre stored.
ConfDir is a string including a trailing directory
delimiter, which points to the directory where the
configuration file is found.
If the STANDARD-MIB is not specified in the Mibs
list, it is loaded from the configuration directory (i.e. with
the .conf files).
If no NetIfModules is specified, the default net if
implementation is used (snmp_net_if).
Prio is an Erlang priority. All SNMP processes
use this priority. Default is the same as default in
the Erlang runtime system.
If no Opts is given, [{name, {local,
snmp_master_agent}}] is default.
start_subagent(ParentAgent,Subtree,Mibs) -> {ok, pid()} |
{error, Reason}
Types:
ParentAgent = pid()
SubTree = oid()
Mibs = [MibName]
MibName = [string()]
Starts a subagent on the node where the function is
called. The snmp_supervisor must be running.
If the supervisor is not running, the function fails with the
reason badarg.
stop_subagent(SubAgent) -> ok | no_such_child
Types:
SubAgent = pid()
Stops the subagent on the node where the function is
called. The snmp_supervisor must be running.
If the supervisor is not running, the function fails with the
reason badarg.
