 Configuration and Performance

 =============================

 

-**datafile** configuration is controlled via a single JSON file called datafile_endpoints.json.

-This is located under datafile-app-server/config.

-

-Json Configuration Explained

-^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-

-Variables of interest (e.g. variables that should be inspected/modified for a specific runtime environment) are listed below for convenience.  The entire file is provided later in this page for reference.

+Configuration

+^^^^^^^^^^^^^

+By default, DFC handles the "PM_MEAS_FILES" change identifier and publishes these files on the "bulk_pm_feed" feed.

+But it can also be configured to handle other change identifiers and publish them to other feeds, see picture below.

+

+.. image:: ../../images/DFC_config.png

+

+The configuration of DFC is controlled via a blueprint.

+

+Blueprint Configuration Explained

+"""""""""""""""""""""""""""""""""

+

+For the communication with the Message Router, the user must provide the **host name**, **port**, and **protocol** of the DMaaP Message router.

+

+.. code-block:: yaml

+  :emphasize-lines: 2,6,10

+

+    inputs:

+      dmaap_mr_host:

+        type: string

+        description: dmaap messagerouter host

+        default: message-router.onap.svc.cluster.local

+      dmaap_mr_port:

+        type: integer

+        description: dmaap messagerouter port

+        default: 3904

+      dmaap_mr_protocol:

+        type: string

+        description: dmaap messagerouter protocol

+        default: "http"

+

+The user can also specify which version of DFC to use.

+

+.. code-block:: yaml

+  :emphasize-lines: 2

+

+    inputs:

+      tag_version:

+        type: string

+        description: DFC image tag/version

+        default: "nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:1.2.0"

+

+The user can also enable secure communication with the DMaaP Message Router.

+

+.. code-block:: yaml

+  :emphasize-lines: 2

+

+    inputs:

+      secureEnableCert:

+        type: boolean

+        description: enable certificate based connection with DMaap

+        default: false

+

+DFC can handle multiple change identifiers. This will require to create manually a new block for each change identifier.

+

+.. code-block:: yaml

+  :emphasize-lines: 2

+  

+    streams_publishes:

+      dfcFeed00ChangeIdentifier:

+        dmaap_info: <<bulk_pm_feed>>

+        type: data_router

+

+For each feed related to a change identifier the user must provide the **feed name**, and **feed description**.

+

+.. code-block:: yaml

+  :emphasize-lines: 2,6

+

+    inputs:

+      dfcFeed00Name:

+        type: string

+        description: The name of the feed the files will be published to. Should be used by the subscriber.

+        default: "bulk_pm_feed"

+      dfcFeed00Description:

+        type: string

+        description: A description of the feed the files will be published to.

+        default: "Feed for Bulk PM files"

+

+**Note!** The feed name provided should be used by the subscriber/s to set up the subscription to the feed.

+

+To dynamically create the feeds, DFC uses the DCAE DMaaP plugin. This means that for each feed the user must also add an

+item under the "**node_templates**" section of the blueprint. The feed is identified within the blueprint with a feed identifier, "**dfcFeed00**" in the example.

+

+.. code-block:: yaml

+  :emphasize-lines: 2

+

+    node_templates:

+      dfcFeed00:

+        type: ccsdk.nodes.Feed

+        properties:

+          feed_name: { get_input: dfcFeed00Name }

+          feed_description: { get_input: dfcFeed00Description }

+

+To configure DFC micro service itself, the user must also add the change identifier and the feed identifier to the "**application_config**" section

+under the tag "**dmaap.dmaapProducerConfiguration**" in the blueprint. **Note!** The identifier should be surrounded by **<<>>** for the feed's configuration to be bound to the DFC configuration in CBS.

+

+.. code-block:: yaml

+  :emphasize-lines: 4

+

+          application_config:

+            dmaap.dmaapProducerConfiguration:

+              - changeIdentifier: {get_input: dfcFeed00ChangeIdentifier}

+                feedInfo: <<dfcFeed00>>

+

+And, lastly, to set up the publication to the feed, the feed identifier must be added to the "**streams_publishes**" section

+of the blueprint.

+

+.. code-block:: yaml

+  :emphasize-lines: 2

+

+          streams_publishes:

+            - name: dfcFeed00

+              type: data_router

+              location: "loc00"
