snmpm_network_interface(3erl) Erlang Module Definition snmpm_network_interface(3erl)
NAME
snmpm_network_interface - Behaviour module for the SNMP manager network interface.
DESCRIPTION
This module defines the behaviour of the manager network interface. A snmpm_network_interface compliant module must export the following
functions:
* start_link/2
* stop/1
* send_pdu/7
* inform_response/4
* note_store/2
* info/1
* get_log_type/1
* set_log_type/2
* verbosity/2
The semantics of them and their exact signatures are explained below.
EXPORTS
start_link(Server, NoteStore) -> {ok, Pid} | {error, Reason}
Types Server = pid()
NoteStore = pid()
Start-link the network interface process.
Server is the pid of the managing process.
NoteStore is the pid of the note-store process.
stop(Pid) -> void()
Types Pid = pid()
Stop the network interface process.
send_pdu(Pid, Pdu, Vsn, MsgData, Addr, Port, ExtraInfo) -> void()
Types Pid = pid()
Pdu = pdu()
Vsn = 'version-1' | 'version-2' | 'version-3'
MsgData = term()
Addr = address()
Port = integer()
ExtraInfo = term()
Request the network interface process ( Pid ) to send this pdu ( Pdu ).
ExtraInfo is some opaque data that is passed to the net-if process. It originates from the ExtraInfo parameter in the calls to the
synchronous get-request , asynchronous get-request , synchronous get-next-request , asynchronous get-next-request , synchronous set-
request and asynchronous set-request functions. Whether the net-if process chooses to use this is implementation dependent. The net-
if process included in this application ignores it.
inform_response(Pid, Ref, Addr, Port) -> void()
Types Pid = pid()
Ref = term()
Addr = address()
Port = integer()
Instruct the network interface process to send the response (acknowledgment) to an inform-request.
Ref is something that can be used to identify the inform-request, e.g. request-id of the inform-request.
Addr and Port identifies the agent, from which the inform-request originated.
note_store(Pid, NoteStore) -> void()
Types Pid = pid()
NoteStore = pid()
Change the pid of the note-store process. This is used when the server re-starts the note_store (e.g. after a crach).
info(Pid) -> [{Key, Value}]
Types Pid = pid()
The info returned is basically up to the implementer to decide. The implementation provided by this application provides info about
memory allocation and various socket information.
The info returned by this function is returned together with other info collected by the manager when the info function is called
(tagged with the key net_if ).
verbosity(Pid, Verbosity) -> void()
Types Pid = pid()
Verbosity = verbosity()
Change the verbosity of the network interface process.
get_log_type(Pid) -> {ok, LogType} | {error, Reason}
Types Pid = pid()
LogType = atl_type()
Reason = term()
The Audit Trail Log is managed by the network interface process. So, it is this process that has to return the actual log-type.
set_log_type(Pid, NewType) -> {ok, OldType} | {error, Reason}
Types Pid = pid()
NewType = OldType = atl_type()
Reason = term()
The Audit Trail Log is managed by the network interface process. So, it is this process that has to do the actual changing of the
type.
See set_log_type for more info.
