Re: [CCAMP] Comments regarding draft-ietf-ccamp-alarm-module-00

Hi Stefan,

Your comment:

Makes sense, I think we should add this capability to the alarm inventory. So the system publishes its possible alarm types (read-only).
But each of those alarm types can have a configurable description leaf.
Ok?

We believe that just a single configurable description leaf would be somewhat restrictive. We would rather take a more generic and extensible direction, whereby a client can map zero or more tagged values as required by his network implementation to an alarm-type-id and/or alarm-type-qualifier-match. For example, something like that shown below.

As configuration:

  +--rw custom-tags {custom-tags}?
     +--rw custom-tag* [alarm-type-id alarm-type-qualifier-match tag-name]
        +--rw alarm-type-id               alarm-type-id
        +--rw alarm-type-qualifier-match  string
        +--rw tag-name                    string
        +--rw tag-value?                  tag-value

In the alarm inventory (state):

  +--ro alarm-type* [alarm-type-id alarm-type-qualifier]
     +--ro alarm-type-id                       alarm-type-id
     +--ro alarm-type-qualifier                alarm-type-qualifier
     +--ro resource*                           string
    :
     +--ro custom-tags {custom-tags}?
        +--ro custom-tag* [tag-name]
           +--ro tag-name   string
           +--ro tag-value? tag-value

Best regards
Nick

and your last comment...

3. Mapping custom information to alarm types

Some operators require to be able to associate their own specific information with alarm types for use within their networks. Such a requirement could be supported within the alarm module through a generic mechanism whereby one or more tag/values could be mapped to an alarm-type-id and/or alarm-type-qualifier-match in a similar way as the list 'x733-mapping' allows a client to override the default X.733 mapping. Any mapped value would also need to be listed within the alarm inventory entry for that alarm-type and included within the 'alarm-notification'.

We believe that it would be advantageous if these additional requirements on alarm management were supported directly within the core alarm module to avoid the situation of each vendor implementing its own solution, which may then lead to interoperability issues between different vendors equipment.

Makes sense, I think we should add this capability to the alarm inventory. So the system publishes its possible alarm types (read-only).
But each of those alarm types can have a configurable description leaf.
Ok?

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Common Control and Measurement Plane WG of the IETF.

Title : YANG Alarm Module
Authors : Stefan Vallin
Martin Bjorklund
Filename : draft-ietf-ccamp-alarm-module-00.txt
Pages : 58
Date : 2017-12-14

Abstract:
This document defines a YANG module for alarm management. It
includes functions for alarm list management, alarm shelving and
notifications to inform management systems. There are also RPCs to
manage the operator state of an alarm and administrative alarm
procedures. The module carefully maps to relevant alarm standards.
