Module Summary
Behaviour module for the SNMP agent notification filters.
Description
This module defines the behaviour of the agent notification filters. A snmpa_notification_filter compliant module must export the following functions:
-
handle_notification/2
The semantics of them and their exact signatures are explained below.
The purpose of notification filters is to allow for modification and/or suppression of a notification.
A misbehaving filter will be removed.
Types
Reply = send | {send, NewNotif} | dont_send
Notif = NewNotif = notification() | trap()
Data = term()
Handle a notification to be sent. The filter can either accept the notification as is, return send, modify the notification, return {send, NewNotif} or suppress the notification, return dont_send.
Data is supplied at filter registration time, see register_notification_filter.
