Previously, the request was built, +and the REST call made, by the application. However, A&AI queries have now been +implemented using the new Actor framework. + +Each operation supported by the actor is associated with its own java class, which is +responsible for populating the request structure and invoking the REST service. The +class hierarchy is shown below. + +.. image:: classHierarchy.png + +Currently, the following operations are supported: + +- Tenant +- Pnf +- CustomQuery + +One thing that sets the A&AI Actor implementation apart from the other Actor +implementations is that it is typically used to gather data for input to the +other actors. Consequently, when an A&AI operation completes, it places its +response into the *properties* field of the *context*, which is passed via the +*ControlLoopOperationParams*. The names of the keys within the *properties* +field are typically of the form, "AAI.<operation>.<targetEntity>", where +"operation" is the name of the operation, and "targetEntity" is the *targetEntity* +passed via the *ControlLoopOperationParams*. For example, the response for +the Tenant query for a target entity named "ozVserver" would be stored as a +*properties* named "AAI.Tenant.ozVserver". + +On the other hand, as there is only one "custom query" for a given ONSET, the +*Custom Query* operation deviates from this, in that it always stores its response +using the key, "AAI.AaiCqResponse". + + +Request +####### + +Most of the the A&AI operations use "GET" requests and thus do not populate +a request structure. However, for those that do, the request structure is +described in the table below. + +Note: the Custom Query Operation requires tenant data, thus it performs a *Tenant* +operation before sending its request. The tenant data is gathered for the vserver +whose name is found in the "vserver.vserver-name" field of the enrichment data provided +by DCAE with the ONSET event. + ++----------------------------------+---------+----------------------------------------------------------------------+ +| Field Name | Type | Description | ++----------------------------------+---------+----------------------------------------------------------------------+ ++----------------------------------+---------+----------------------------------------------------------------------+ +| Custom Query: | | | ++----------------------------------+---------+----------------------------------------------------------------------+ +| *start* | string | Extracted from the *result-data[0].resource-link* field of the | +| | | Tenant query response. | ++----------------------------------+---------+----------------------------------------------------------------------+ + + +Examples +######## + +Suppose the *ControlLoopOperationParams* were populated as follows, with the tenant +query having already been performed: + +.. code-block:: bash + + { + "actor": "AAI", + "operation": "CustomQuery", + "context": { + "enrichment": { + "vserver.vserver-name": "Ete_vFWCLvFWSNK_7ba1fbde_0" + }, + "properties": { + "AAI.Tenant.Ete_vFWCLvFWSNK_7ba1fbde_0": { + "result-data": [ + { + "resource-type": "vserver", + "resource-link": "/aai/v15/cloud-infrastructure/cloud-regions/cloud-region/CloudOwner/RegionOne/tenants/tenant/3f2aaef74ecb4b19b35e26d0849fe9a2/vservers/vserver/6c3b3714-e36c-45af-9f16-7d3a73d99497" + } + ] + } + } + } + } + +An example of a Custom Query request constructed by the actor using the above +parameters, sent to the A&AI REST server: + +.. code-block:: bash + + { + "start": "/aai/v15/cloud-infrastructure/cloud-regions/cloud-region/CloudOwner/RegionOne/tenants/tenant/3f2aaef74ecb4b19b35e26d0849fe9a2/vservers/vserver/6c3b3714-e36c-45af-9f16-7d3a73d99497", + "query": "query/closed-loop" + } + + +An example response received from the A&AI REST service: + +.. code-block:: bash + + { + "results": [ + { + "vserver": { + "vserver-id": "f953c499-4b1e-426b-8c6d-e9e9f1fc730f", + "vserver-name": "Ete_vFWCLvFWSNK_7ba1fbde_0", + "vserver-name2": "Ete_vFWCLvFWSNK_7ba1fbde_0", + "prov-status": "ACTIVE", + "vserver-selflink": "http://10.12.25.2:8774/v2.1/41d6d38489bd40b09ea8a6b6b852dcbd/servers/f953c499-4b1e-426b-8c6d-e9e9f1fc730f", + "in-maint": false, + "is-closed-loop-disabled": false, + ... + } + + +Configuration of the A&AI Actor +############################### + +The following table specifies the fields that should be provided to configure the A&AI +actor. + +=============================== ==================== ================================================================== +Field name type Description +=============================== ==================== ================================================================== +clientName string Name of the HTTP client to use to send the request to the + A&AI REST server. +timeoutSec integer (optional) Maximum time, in seconds, to wait for a response to be received + from the REST server.
