Behaviour module for the SNMP agent notification delivery information receiver.
This module defines the behaviour of the notification delivery information receiver.
A snmpa_notification_delivery_info_receiver
compliant module
must export the following functions:
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.
Functions
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.
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 delivery (was the notification acknowledged or
not) for each target.
