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.
Legacy API function send_pdu/7 that has got separate IpAddr and Port-
Number arguments still works as before for backwards compatibility rea-
sons.
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, Domain, Addr, ExtraInfo) -> void()
Types:
Pid = pid()
Pdu = pdu()
Vsn = 'version-1' | 'version-2' | 'version-3'
MsgData = term()
Domain = transportDomainUdpIpv4 | transportDomainUdpIpv6
Addr = {inet:ip_address(), inet:port_number()}
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, syn-
chronous get-next-request, asynchronous get-next-request, syn-
chronous 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 ig-
nores 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 (ac-
knowledgment) to an inform-request.
Ref is something that can be used to identify the inform-re-
quest, e.g. request-id of the inform-request.
Addr and Port identifies the agent, from which the inform-re-
quest 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.
