NAME
snmpa_notification_delivery_info_receiver -
Behaviour module for the SNMP agent notification delivery
information receiver.
DESCRIPTION
This module defines the behaviour of the notification delivery informa-
tion receiver.
A snmpa_notification_delivery_info_receiver compliant module must ex-
port the following functions:
* delivery_targets/3
* delivery_info/4
The semantics of them and their exact signatures are explained below.
Legacy notification delivery information receiver modules used a target
argument on the form {IpAddr, PortNumber} instead of {Domain, Addr},
and if the SNMP Agent is run without changing the configuration to use
transport domains the notification delivery information receiver will
still get the old arguments and work as before.
DATA TYPES
See the data types in snmpa_conf.
EXPORTS
delivery_targets(Tag, Targets, Extra) -> void()
Types:
Tag = term()
Targets = [Target]
Target = {transportDomain(), transportAddressWithPort()
Extra = term()
Inform about target addresses.
This is the first function called when a notification delivery
is in progress. It informs the receiver which targets will get
the notification. The result of the delivery will be provided
via successive calls to delivery_info/4 function, see below.
delivery_info(Tag, Target, DeliveryResult, Extra) -> void()
Types:
Tag = term()
Targets = [Target]
Target = {transportDomain(), transportAddressWithPort()
DeliveryResult = delivery_result()
delivery_result() = no_response | got_response
Extra = term()
Inform about delivery result.
This function is called for each target in the Targets argument
of the delivery_targets/3 function, see above.
The purpose is to inform the receiver of the result of the de-
livery (was the notification acknowledged or not) for each tar-
get.
