Summary of Changes
------------------

* **Requirements Added:** 1
* **Requirements Changed:** 14
* **Requirements Removed:** 2


Monitoring & Management > Data Structure Specification of the Event Record
--------------------------------------------------------------------------


Requirements Changed
~~~~~~~~~~~~~~~~~~~~


.. container:: note

    :need:`R-520802`

    The VNF or PNF provider **MUST** provide a YAML file formatted in adherence with
    the :ref:`VES Event Registration specification <ves_event_registration_3_2>`
    that defines the following information for each event produced by the VNF:

    * ``eventName``
    * Required fields
    * Optional fields
    * Any special handling to be performed for that event


.. container:: note

    :need:`R-570134`

    The events produced by the VNF or PNF **MUST** must be compliant with the common
    event format defined in the
    :ref:`VES Event Listener<ves_event_listener_7_1>`
    specification.


.. container:: note

    :need:`R-120182`

    The VNF or PNF provider **MUST** indicate specific conditions that may arise, and
    recommend actions that may be taken at specific thresholds, or if specific
    conditions repeat within a specified time interval, using the semantics and
    syntax described by the :ref:`VES Event Registration specification <ves_event_registration_3_2>`.


ONAP Heat Orchestration Template Format > Heat Orchestration Template Structure > resources > properties
--------------------------------------------------------------------------------------------------------


Requirements Changed
~~~~~~~~~~~~~~~~~~~~


.. container:: note

    :need:`R-10834`

    A VNF's Heat Orchestration Template resource attribute ``property:``
    **MUST NOT** use more than two levels of nested ``get_param`` intrinsic
    functions when deriving a property value.  SDC does not support nested
    ``get_param`` with recursive lists (i.e., a list inside list).
    The second ``get_param`` in a nested lookup must directly derive its value
    without further calls to ``get_param`` functions.

    * Example of valid nesting:

      * ``name: {get_param: [ {vm-type}_names, {get_param : index } ] }``

    * Examples of invalid nesting.  SDC will not support these examples since
      there is an array inside array.

      * ``name: {get_param: [ {vm-type}_names, { get_param: [ indexlist, 0 ] } ] }``
      * ``name: {get_param: [ {vm-type}_names, { get_param: [ indexlist1, { get_param: indexlist2 } ] } ] }``

    A VNF Heat Orchestration Template's Base Module file name **MUST** include
    case insensitive 'base' in the filename and
    **MUST** match one of the following four
    formats:

     1.) ``base_<text>.y[a]ml``

     2.) ``<text>_base.y[a]ml``

     3.) ``base.y[a]ml``

     4.) ``<text>_base_<text>``.y[a]ml

    where ``<text>`` **MUST** contain only alphanumeric characters and
    underscores '_' and **MUST NOT** contain the case insensitive string
    ``base`` or ``volume``.

    section
    **MUST** only be defined using one of the following:

    * one of more ``OS::Cinder::Volume`` resources
    * one or more ``OS::Heat::ResourceGroup`` resources that call a nested YAML
      file that contains only ``OS::Cinder::Volume`` resources
    * a resource that calls a nested YAML file (static nesting) that contains
      only ``OS::Cinder::Volume`` resources
